hillsdale drivers rely on their car’s coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your sedan engine and absorbs heat. The mixture then flows out to the radiator where it’s cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.

There’s a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that’s easily reached inside your sedan’s engine, so it can turn to steam which does not conduct heat as well and is harder to contain.

Also, if it’s freezing outside in hillsdale, the water in your engine could freeze while your vehicle is sitting out in the cold.

So, if you remember your hillsdale high school chemistry, you’ll know that a mixture has both a higher boiling point and a lower freezing point than either component alone.

Coolant, or antifreeze, is specially formulated to keep your engine safe in a wide range of environmental and operating temperatures in and around hillsdale.

Whenever the sedan is running, the coolant in the cooling system is working to keep your engine from overheating. When it’s cold outside, the coolant acts as antifreeze to keep the fluid from freezing in your engine.

All that exploding fuel in your engine creates a lot of heat. Without coolant, the metal sedan engine parts would expand so much that the engine would seize up and stop running. Expensive parts could be broken or warp so badly they would have to be replaced. It could even be so bad that the whole sedan’s engine is ruined and has to be junked.

This is why it is critical that hillsdale drivers check coolant levels frequently and have their sedan cooling system inspected for leaks. Also your sedan manufacturer has a maintenance requirement for draining and replacing your coolant. These recommendations can vary widely, so check your owner’s manual or ask us at Layman’s Service Center in hillsdale.

The reason you need to change the coolant is that it has additives in it to protect the cooling system. As you can imagine, with all the heat, the cooling system’s a pretty harsh environment. The additives keep the fluid from becoming corrosive and damaging the radiator and other sedan cooling system components. Over time, the additives are depleted and the coolant just has to be replaced.

Many hillsdale auto owners ask Layman’s Service Center why there are different colors of antifreeze. It is very important that you use the correct type of antifreeze. The different types of antifreeze – or coolant – are different colors so you don’t mix them up.

Auto manufacturers use different materials to make the cooling system, and they require different types of antifreeze to protect them.

So check with us at Layman’s Service Center or your owner’s manual for the right kind because using the wrong coolant can void the warranty for your sedan cooling system.

Today’s Layman’s Service Center post focuses on using the proper fluids for your vehicle. Big advances in automotive technology have lead to the development of high-tech fluids to keep pace. Some because of engineering advances and others, advances in the materials used to build sedan automotive systems.

A simple example of this is the cooling system. For decades it was primarily made out of iron, steel and rubber hoses. There was one kind of coolant that protected these components from corrosion.

Now cooling system components are made with various metal alloys and plastics. These materials require different additives to protect them from corrosion. Since the materials used vary from manufacturer to manufacturer, we now have a number of different kinds of coolant.

And it’s important that Jonesville car owners use the right coolant. If you pour in the wrong kind, it won’t protect the cooling system and may even void the warranty. Check your sedan owner’s manual. Of course, your Layman’s Service Center advisor will know the proper coolant to use.

Brake fluid is confusing for some Jonesville drivers. Back when we opened shop 40 years ago, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some Jonesville people mistakenly think the higher numbers are an upgrade. You know, if 3 is good then 4 must be better. That’s not how it works. They are different formulations to meet the demands of differences in brake systems. Only one of them is recommended for your sedan.

Transmission fluid is the same thing. For decades there were two basic types of tranny fluid used at Layman’s Service Center: friction modified or not. With the tremendous engineering advances in sedan automatic transmissions, there have been several new types of fluids developed to protect and lubricate them.

Nowhere are the advances in automotive fluids more evident to Jonesville motorists and Layman’s Service Center professionals than in motor oil. Many new weights and formulations have been created to meet the demands of today’s modern sedan engine design. Modern engines have more parts and much tighter tolerances. Every year, engines make more power and get better fuel economy. And with all the complication and sophistication, they still have to be durable.

That’s where the new grades of engine oil come in. They have to be formulated to lubricate, protect and clean all of those sedan engine parts, big and little. The oil has to be thin enough to get into little passages, yet resistant to vaporization.

At Layman’s Service Center, we believe that in some ways modern automotive fluids are just as great feats of engineering as the new engines. Because weights of oil and types of coolant and transmission fluid are so carefully matched to the vehicle, take care to always use the proper fluid if you are topping off at home.

Check your sedan owner’s manual or ask your Jonesville service advisor. The wrong fluid can cause damage. If you drive a car or truck with 75,000 miles or more, consider high mileage formulations. These fluids contain extra detergent to clean dirtier older engines as well as additives to condition seals and gaskets. That’ll help prevent leaks. Always be sure that the high mileage fluid is the same weight or type of fluid recommended for your vehicle.

High gas prices in hillsdale have hit most of our budgets. You’ve probably budgeted a certain amount for vehicle related stuff. Increased fuel costs are now consuming a bigger portion of that budget and you may be tempted to skimp in some other areas – like scheduled maintenance.

According to news reports and industry studies, you’re not alone. Nine out of ten personal vehicles on the road have at least one maintenance or repair item that hasn’t been done. Some of these items are serious safety concerns. Others are just more likely to affect the cost of operating your vehicle.

In this area, we can take a lesson from professional hillsdale vehicle owners. I’m talking about fleet owners and operators. You know, hillsdale folks like the trucking companies and delivery services. Because their livelihood depends on it, they have gotten scheduled maintenance down to a science. And the last thing they skimp on is regular maintenance.

Why is that? Well, for one thing they know that routine maintenance prevents expensive repairs and costly breakdowns. They also know that a well-maintained vehicle uses less fuel. For them, even a small decrease in fuel economy may mean not being profitable.

So what does this mean to hillsdale drivers? Well, there’s a ninety percent chance that you’re missing some service that would improve your fuel economy. Here’s a quick reminder list:

Fuel system cleaning, transmission service, differential service, engine air filter, wheel alignment, oil change, tune up.
Ring any bells? Can you honestly say that there isn’t at least one thing on the list that hasn’t been done?

Let’s suppose you chose to spend one hundred and fifty dollars and get caught up on some of these services at Layman’s Service Center. Figure that they combine to improve your fuel economy by fifteen percent. What would that mean to your pocketbook?

Well, the average personal vehicle in hillsdale is driven about twelve thousand miles a year. If you get twenty miles per gallon in your sedan, over the course of one year you would pay for the hundred and fifty dollars worth of service and save an additional hundred and sixty five dollars if gas is at three dollars and fifty cents. If gas is four fifty, you would save two hundred and fifty-five dollars. And you’d rack up savings of three hundred and forty five dollars with gas at five and a half bucks.

From this you can see that the more fuel costs, the more it pays to take care of your sedan. Some of us drive trucks in hillsdale for work or recreation – or want a large SUV for family needs. A fifteen percent improvement in fuel economy can generate huge savings – six hundred and sixty dollars a year if gas is four fifty a gallon in hillsdale. Take a look at this table to see where your savings could lie.

So catch up on those services you’ve been neglecting at Layman’s Service Center. Get a couple done now and a couple next time. Chances are you’ll save a lot of money at hillsdale gas pumps this year – and a lot more on repairs in years to come.

Your sedan requires plenty of clean fuel to run. When your fuel isn’t clean, your fuel injectors can start to become clogged up. When this happens, your sedan engine may not get the proper amount of fuel at the correct pressure to run efficiently. This hurts fuel economy and performance as you drive around Coldwater. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.

That’s why all vehicles, including sedans, come equipped with a fuel filter somewhere between the engine and the fuel tank. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and holds them out of the fuel stream. Of course, the filter will eventually get clogged up and need to be replaced at Layman’s Service Center.

If your fuel filter is clogged, the sedan engine can’t get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your engine running, but doesn’t protect it from contaminated fuel.

You may find that you need to change your fuel filter at Layman’s Service Center more frequently as your sedan ages. Over the years, additional sediment and rust accumulates in the fuel tank and can be drawn into the fuel system. Your fuel filter stands guard at the gates to your engine to protect expensive parts and to maintain performance and fuel economy.

Most of our Hudson clients want to save on gas and seek our advice on improving fuel economy. At Layman’s Service Center, we are frequently asked, however, just how much money Hudson motorists can actually save.

Well the US government has a website dedicated to helping us use less fuel. It presents the cost savings in a way Hudson car owners can relate to and is relevant for all vehicles. Let me give you an example: Having your sedan engine properly tuned, can save up to 4%. If you’re paying three-fifty for a gallon of gas, you could save fourteen cents a gallon.

In today’s Layman’s Service Center post, we’re going to talk about several things you can do to improve your sedan fuel economy driving around Hudson. We’ll tell you the potential savings per gallon of gas at three dollars and fifty cents, and we’ll show a graphic that also shows the savings at three and four dollars.

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best economy. A clean air filter means you get plenty of air. The fact that the air’s clean protects your engine. That can save you up to ten percent or thirty-five cents a gallon.

Fixing a faulty oxygen sensor can improve economy by up to forty percent. That’s a whopping dollar forty in savings per gallon. Bring your car to Layman’s Service Center and we’ll check your oxygen sensor.

Chances are that if your oxygen sensor is kaput your check engine light will come on. Now, there’s any number of things that could cause your check engine light to come on besides oxygen sensor problems. But if it’s on, get it checked out as soon as you can at Layman’s Service Center.

Here’s an easy one. Inflate your tires to the recommended pressure. That could save you three percent or eleven cents a gallon. Even a little drop in pressure will cost you at the pump so check your tires every week.

Your sedan manufacturer has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced fuel economy, or up to seven cents a gallon.

Here’s one that’s free: Take it easy when you drive. Aggressive driving (we’ve all seen this on Hudson roads), rocketing away from stop lights, standing on the brakes, punching it for lane changes – really takes a toll on your fuel economy.

Cutting out aggressive driving around Hudson can save five percent or eighteen cents a gallon. Now on the highway it gets really costly: thirty three percent or a buck sixteen a gallon. Think about that.

 A related item is exceeding the speed limit. For example, if the speed limit is sixty miles per hour an additional five miles will cost seven percent or twenty-five cents a gallon. Fifteen miles per hour will cost you upwards of eighty cents a gallon.

The last thing we’ll talk about is excess weight. Our sedans tend to accumulate a lot of things and the weight adds up. Clear out the trunk and only haul stuff when you really need it. For every one hundred pounds you can save two percent or seven cents a gallon.

Sorry honey, your brother can’t come with. It’d cost an extra thirty cents a gallon.

When it comes to their vehicles, some Coldwater people don’t have a maintenance mindset. They know they need to take care of their cars, but it just seems really hard to get them to remember to do it. Coldwater drivers generally accept that many things in life require regular maintenance, but just may have not applied it to their sedans.

For example: the lawn. You water it and mow it every week. And weed the flower beds and rake the leaves. There are other things that Coldwater people are good about maintaining. Going to the dentist twice a year. Clothes to the dry cleaner. Flu shots. Taking the kids to your Coldwater doctor for a checkup before school starts.

So Coldwater people really are maintenance minded. They just have to learn to apply that mindset to cars. I mean, if you never brush your teeth or go to the dentist, you’ll become painfully aware of your neglect when you get a big cavity. Once the damage is done, we learn our lesson and start to take better care of things.

Unfortunately, Coldwater sedan owners too often learn the hard automotive lesson when they bring their vehicle to Layman’s Service Center on a tow truck. So many times a little routine maintenance would have prevented a breakdown.

So how can Coldwater drivers get into the habit of taking care of their sedan? It’s so easy to forget. If you skip cutting the grass, you see it every time you pull in the driveway.

Here’s something that will help: The key to good vehicle maintenance starts with the oil change. Think about it – when you go in for a full-service oil change, your Layman’s Service Center tech will check all your fluids. If one of them is low, he can look for the reason why. If your serpentine belt is cracked, he’ll see it and let you know. Corroded battery cable – they’ve got you covered. And at Layman’s Service Center, we check to see if your sedan manufacturer has recommended any services at your current mileage.

The oil change becomes kind of a focal point, a way to check in to see what needs to be done. The fact is that vehicle inspection surveys consistently reveal that over 80% of vehicles have one or more unperformed repair or maintenance service. Vehicles are generally very reliable and can take a lot of abuse and neglect. But, you’ve got to remember that sedans are complicated machines. There are parts and fluids that are critical to their function. Without them, the sedan won’t run at all.

So when you come in to Layman’s Service Center for an oil change, you get a visual inspection from your honest service advisor and a reminder for recommended services so you can avoid a total failure. And remember that your Layman’s Service Center service advisor can help you work out a maintenance and repair plan, prioritizing and scheduling the work to make sure you and your family are safe, and avoid expensive breakdowns.

If you’ve ever heard a squealing sound under your hood, chances are it was your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems in your sedan. Let’s go over them.

First, the serpentine belt drives your air conditioning system. It spins the compressor that makes the cool air that takes the edge off the summer heat in hillsdale.

Next, the belt powers the alternator. The alternator creates electricity that’s used by your sedan’s electrical systems and also charges your car battery. Without the alternator, the battery will go dead in a few miles.

The serpentine belt may also run the pumps for both the power steering (some are electric) and power brakes (some use vacuum boost).

And, on most sedans, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within normal operating temperatures. On some hillsdale cars, the water pump is powered by the timing belt instead of the serpentine belt.

When they understand what it does, hillsdale drivers realize that if it breaks, it affects a lot of systems. That’s why manufacturers have recommended that it be changed every so often so that it doesn’t fail.

At Layman’s Service Center, we can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon. If the belt has more than three or four cracks every inch, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny glazed look, it needs to be replaced regardless of age or mileage.

If it has lost a significant thickness, it also needs to be replaced. There’s a special spring-loaded pulley attached to the engine called the tensioner pulley. Its job is to make sure there’s a constant tension on the serpentine belt so that it doesn’t slip. The spring can become worn and no longer provide the necessary pressure to keep the belt tight. At Layman’s Service Center, we recommend that the tensioner be replaced at the same time as the serpentine belt.

As mentioned, a squealing sound could be a sign that the serpentine belt needs to be replaced. It may be loose if you hear a slow, slapping sound when idling your sedan.

All in all, the serpentine belt’s an important part for the function of your sedan. And it’s not that expensive to replace at Layman’s Service Center – so it’s good to do so before it fails.

Many hillsdale drivers have been hearing about new advances in power steering technology, specifically, electric power steering. Some very high-end cars have been featuring electric power steering for a few years. An electric motor directly provides the power assist to make steering easier. Undoubtedly we’ll see much more of this in hillsdale as full electric cars and electric hybrids become more common.

The vast majority of cars and trucks serviced at Layman’s Service Center in hillsdale use a hydraulic power boost system. With hydraulics, fluid is pressurized by a pump which actuates a hydraulic cylinder to reduce steering effort. Some of these pumps are powered by an electric motor. Most pumps are powered by the serpentine belt driven by the engine.

Power steering fluid has the necessary hydraulic properties and the ability to lubricate the internal parts. The power steering fluid also protects sedan components from rust and corrosion.

hillsdale car owners should be aware that manufacturers recommend that the fluid be replaced on schedule. At Layman’s Service Center, the old fluid is drained and the system cleaned thoroughly. Fresh fluid is then installed.

Unfortunately, many hillsdale people don’t realize how important it is to service their power steering, or even that it should be done at all. A neglected power steering system can develop leaks and the pump won’t last as long.

Signs that you may be having problems with your power steering include the need to constantly add power steering fluid, a loud whining from the pump, erratic power assist or high steering effort. If you’re experiencing any of these problems, have your power steering checked out at Layman’s Service Center in hillsdale.

In addition to the pump and hydraulic system, there are mechanical parts in the steering system. The rods, arms, joints and knuckles that actually turn the wheels can become worn or damaged. A standard alignment service includes an inspection of steering components.

If you notice any play in the steering wheel, that the steering wheel is off center, or a noise coming from your front wheels, especially when turning, have your Layman’s Service Center advisor do an inspection so the problem can be corrected. Waiting too long could cause uneven tire wear and may even lead to steering failure. Call Layman’s Service Center today at 517-437-3821.

Today in the Layman’s Service Center auto care blog, we’re going to talk about oil change intervals. It seems that as engine technology advances, recommended oil change intervals have gotten longer for Layman’s Service Center customers. High quality oil in a well-engineered sedan engine has lead to extended intervals. But it’s also lead to some confusion among hillsdale drivers.

The old mantra “change your oil every three months or three thousand miles, whichever comes first” once applied to every vehicle in your garage. Time and miles take their toll on motor oil. But now, you could have a different oil change recommendation for every car or truck you own.

hillsdale people are like everybody else, they have a tendency to put off all the oil changes to the schedule of the vehicle with the longest interval. Of course, that can lead to problems. For example, recently four of the world’s largest auto manufacturers shortened the published intervals for several of their engines. They originally published intervals that extended out to a much as 8,000 miles.

In real world hillsdale driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance. Quite literally petroleum jelly – like Vaseline. This goop was clogging sedan small engine passages so the oil wouldn’t flow to some parts of the engine. This resulted in engine damage. We see it from time to time at Layman’s Service Center.

The manufacturers began to offer an extended warranty to cover sludge damage. But there was a catch: the vehicle owner had to follow a new, lower service interval, and provide proof of oil changes in order to make a warranty claim.

So here’s the problem. With longer oil change intervals, it’s extremely important to follow them closely. Back in the day of 3 months or 3,000 miles, if you went an extra month or an extra thousand miles, your oil was still fresh enough that it didn’t have time to build up much sludge.

But if your recommended interval is 6,500 miles and you go over another thousand, you’re getting into heavy sludge territory. You absolutely need to follow mileage intervals very closely. And don’t forget your severe service schedule. If you do a lot of stop and go driving in mi, short trips, drive in dusty or polluted hillsdale conditions, hot or cold weather, or haul heavy loads, you’re driving in severe service conditions. Your Layman’s Service Center advisor can help you evaluate which schedule to follow.

So check your sedan owner’s manual or talk with your hillsdale service advisor about where and how you drive. Should you be changing your oil closer to the regular schedule, or the severe service schedule? You need to make the call.

Let me give you an example of this. Some newer sedans have an oil change indicator. It has a sophisticated computer algorithm that tracks number of cold starts, engine temperature, RPMs, mileage, and many more variables to come up with a recommendation for when to change the oil.

Depending on driving conditions, the indicator in one test vehicle came on at anywhere from 2,500 miles to almost 7,000 miles. It’s typically just over 4,000 miles. What this tells us is that sometimes, we’re driving easy miles that are easy on the sedan – like a long road trip. Sometimes, we’re driving hard mi miles – like towing a trailer or a lot of around town driving. But, usually, it’s a combination of both.

Once again, it’s up to you to make the call as to when to change your oil at Layman’s Service Center to protect your sedan engine. Another place where mi drivers can go wrong is with the type of oil they use. More and more new cars are coming to hillsdale owners filled with synthetic oil. Without going into a lot of detail right now, let’s just say that synthetic oil lasts longer and is very resistant to oil sludge.

But it also costs quite a bit more, so some hillsdale people are tempted to use conventional oil for their oil changes. Now, it’s always best to use the oil recommended by your manufacturer. Check your owner’s manual see if a conventional oil alternative is allowed.

But getting back to the problem, if your sedan came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil. If you use conventional oil, you can’t use the synthetic interval. You need to shorten it.

A while back, the Cash for Clunkers program was all over the news. hillsdale people could trade in their old vehicle for a new one that got better fuel economy and receive a government rebate.

A lot of hillsdale motorists had so-called clunkers that they wanted to keep. They’re good commuters, grocery getters or toy haulers. They enjoy that fact that they’re paid off, or soon will be. They would gladly like to keep their sedans for 200,000 miles or more – as long as it’s economical to do so.

There are plenty of hillsdale drivers whose vehicles are running after 150,000 or 200,000 miles. We can learn from what they’re doing to keep our own sedans on the road in mi.

hillsdale drivers of high-mileage cars often report a common denominator of never skipping an oil change. That may sound a bit unsophisticated, but it’s really not. First off, oil is the life blood of your sedan’s engine and it needs to be clean to properly lubricate. Skipping oil changes leads to clogged oil filters and sludge that can damage your engine.

There’s another reason why the scheduled oil change is so important for hillsdale car owners. It’s simple – a Layman’s Service Center professional is going to be looking at your car. All of your fluid levels will be inspected and topped off so they won’t get so low that damage can be done. If there is a significant fluid loss, let’s use brake fluid as an example, your Layman’s Service Center technician can look for the cause of the loss and find the problem before it leads to an accident or costly repair.

Your Layman’s Service Center advisor will also visually inspect your sedan for worn belts and hoses, uneven tire wear, leaking shock absorbers and more. Problems get addressed before they lead to repairs that cost more than the car’s worth.

And your Layman’s Service Center advisor will be able to remind you of other services that the factory recommends you get done. Just think of that oil change the same way as you do about going to your hillsdale dentist for your six month cleaning and checkup. Don’t skip it.

Realistically, things are going to wear out as your sedan gets older. On the way to 200,000 miles you’ll go through several batteries, probably a couple of alternators and water pumps, a set of shocks and likely some brake rotors.

Of course, these things cost money, but they are far cheaper than new sedan payments. With proper service at Layman’s Service Center and regular inspections, you’ll keep surprise repairs to a minimum and more money in your wallet.
