• Coolant Service at Bob & Dave’s Garage

      0 comments

    Wyoming car owners’ cars have to operate in a wide range of Michigan temperatures which requires our engine coolant to be able to perform ‘no matter what’. Think for a moment about the environment where the coolant does its thing. Very hot, high pressure, corrosive…

    And all the while, it has to protect the components of the cooling system from corrosion. These components are made from steel and aluminum, plastics and rubber. The coolant has to be formulated to protect against corrosion for all of these different materials. That’s why auto makers recommend different types of anti-freeze for our Wyoming, Michigan vehicles.

    There are several different ‘families’ of anti-freeze available to us here in Wyoming, Michigan. Your owners’ manual will tell you what kind you should use. Of course, the automotive professionals at  Bob & Dave’s Garage will know the right kind for your car.

    It’s vital to stay on top of this because coolant system failure is the most common mechanical problem people have here in Wyoming, Michigan. Regular service at Bob & Dave’s Garage needs to be done to avoid failures and also to keep your warranty in place.

    While the specifics of the service required may vary from vehicle to vehicle, your committed to excellence, fairness and customer service Bob & Dave’s Garage service professional will know what to do. You’ll be advised to replace the coolant at specified intervals.

    Some manufacturers recommend periodic coolant system flushes. A flush adds a cleaning step to the fluid replacement process. Again, check to see what your Wyoming tech recommends.

    Someday, you may have to deal with an overheating problem, so you need to know what to do if your coolant temperature warning light comes on or your temperature gauge is in the hot zone.

    Now, overheating can be very expensive. Wyoming auto owners can literally melt down their engine and have to replace the whole thing. So don’t ignore warning signs.

    First turn off the air conditioner. This will lower engine temperature right away. Next, crank up your heater to maximum heat and run the fan at high speed. You might need to roll down the windows, but this will take a lot of heat off the engine.

    Pull over as soon as you can safely do so
    , especially if you are stuck in slow-moving traffic, and shut the car off. It may take as much as 45 minutes for the engine to cool to the point that it’s safe to operate the car again.

    If you need to add water or antifreeze, be sure to wait until the car cools down. Opening the radiator cap or even the overflow bottle when the coolant is hot and under pressure may result in serious burns.

    After the engine has cooled for 45 minutes or so, look to see if the coolant is low in the overflow tank. If so, you can cover the overflow tank cap with a large cloth and open the lid. Then start the engine and pour in some water or antifreeze. Pouring it in when the car is running will circulate the new, cool fluid with the warmer fluid in the engine and avoid engine damage.

    Of course, overheating is a serious problem and you need to get it fixed right away. Bob & Dave’s Garage can make sure the coolant is right before you drive home.

    Those spring and winter inspections really come in handy when they head off a cooling system problem. And don’t forget that severe service driving conditions, like towing or hot, dusty driving around Wyoming, Michigan, mean that you’ll need to service your coolant more frequently.

    At AutoNetTV, we suggest that you have Bob & Dave’s Garage inspect your coolant system to find small problems before they become big, and to change belts and hoses before they fail. After all, we don’t want you to lose your cool out there in Wyoming, Michigan.

  • Water Pump

      0 comments

    Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your car from overheating. There are five main components to the cooling system:

    • the radiator
    • the radiator cap
    • the hoses
    • the thermostat and
    • the water pump

    The cooling system is vital for Wyoming car owners. It circulates coolant through the radiator and your engine to protect your vehicle from overheating. There are five main components to the cooling system:

    the radiator
    the radiator cap
    the hoses
    the thermostat and
    the water pump

    The water pump’s like the heart of your cooling system, circulating the fluid throughout your vehicle. It’s a small pump that’s driven by the engine; usually by belt, but sometimes by a chain or gear.

    The water pump only operates when the engine’s running. Water pump failure is pretty routine. We see it often at Bob & Dave’s Garage. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Consult your auto maker’s owners’ manual or committed to excellence, fairness and customer service Bob & Dave’s Garage service professional to see what’s recommended.

    Since a water pump either works or it doesn’t, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It’s possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

    So how can Wyoming car owners tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump – it’s got a problem. If you can see coolant in that area, you’ve got a leak.

    Some water pumps are driven off the timing belt. They might be under a plastic cover so you can’t see the water pump. Look for coolant on the driveway. If you see some, have your Bob & Dave’s Garage technician check it out.

    Most timing belts need to be changed at 60,000 miles – some longer. It’s a good idea to change your water pump at the same time if it’s one of those that’s driven off the timing belt. To start with, 90% of the work’s already done with the timing belt change. And, if you don’t, and develop a leak later, you’ll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

    Wyoming auto owners can replace a failed water pump with a brand spankin’ new one or with a rebuilt pump. Rebuilt will save you some money, but ask your committed to excellence, fairness and customer service Bob & Dave’s Garage technician what he thinks. Don’t feel too bad if your water pump gives out. They will all wear out eventually. Your Bob & Dave’s Garage technician can get you back on the road and on with your life.

  • Cooling System Components

      0 comments

    Today we want to talk about a very important system in our cars – the cooling system. It’s one of those things that you don’t give much thought to until it fails and then you’re stranded by the side of the road.

    Cooling systems fail more often than any other mechanical system – usually because of neglect. Don’t you hate it when something breaks, and you could have done something to prevent it?

    The good news is that if you take care of your cooling system it can keep working for the life of your car.

    Here at AutoNetTV, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, the thermostat, the radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.

    It sounds complicated, but we don’t have to be experts – we can leave that to our committed to excellence, fairness and customer service service technicians at Bob & Dave’s Garage. But, having an overview will help us remember to take care of our cooling systems.

    Most people would be surprised to know that burning fuel in your engine produces up to 4,500 degrees of heat. And all that heat has to be dealt with. If the heat can’t be drawn off the engine, the pistons will literally weld themselves to the inside of the cylinders – then you just have to throw the engine away and get a new one. That would cost thousands of dollars.

    Now the water pump is what forces the coolant through passages in the engine to absorb heat. The pump is driven by a belt that needs replacement from time to time. And the water pump will eventually wear out and need to be replaced. Spending some money on replacing the belts and water pump is much less than the cost of repairing the massive damage that can be done when an engine seizes.

    There’s another little part of the coolant system that protects the engine. It’s called a freeze plug. If you remember from high school chemistry, water expands when it freezes. In very cold areas, the coolant can actually freeze when the vehicle is left sitting.

    It is hard to believe, but the expanding frozen coolant can actually crack the engine block. The freeze plugs fit into the engine block. They fit tight enough to withstand the pressure of a running engine, but can expand or pop out if the coolant freezes. These little things save a lot of engine blocks.

    That brings up a good point. An engine has to work in all kinds of temperatures – extremely hot as well as very cold. How does the cooling system adapt to external temperatures as well as varying operating conditions?

    Well, it’s much like the way you keep your house at a comfortable temperature all year round – with a thermostat. The thermostat in your car controls how much coolant flows through your engine. When the engine is cold, it restricts coolant flow until the engine comes up to an efficient operating temperature. Then it starts opening up to move more coolant to keep the temperature within a specified range.

    The thermostat needs to be replaced from time to time as well. It’s easy to diagnose a failed thermostat and is fairly inexpensive to replace. We can do this for you at Bob & Dave’s Garage in Wyoming, just give us a call: 616-532-7209. Now we’ve been talking about all this heat we’ve got to get rid of, but haven’t really talked about where it goes. That’s where the radiator comes in. The hot coolant passes through the radiator. Air flows past the cooling fins and cools the coolant.

    The radiator has two tanks that hold coolant: sometimes one the top and bottom or one on either side. If you have an automatic transmission, one of the tanks will also contain a second tank that cools the transmission fluid. Large SUV’s and trucks often have a separate transmission cooler. So when you drive around Wyoming, the air is forced past the radiator. But driving doesn’t produce enough air flow. So the radiator has cooling fans that force fresh air over the radiator. These fans may be powered by a belt or by electric motors.

    Now, you also have something called a heater core. The heater core is like a mini radiator. A small fan blows air over the heater core and into the passenger compartment of your vehicle. That’s how you warm your car when it’s cold out.

    Next is the radiator cap. With most newer cars around Wyoming, you never remove the radiator cap, except to replace it. You add coolant through the overflow tank. The radiator cap is also called a pressure cap, because its job is to maintain pressure in the cooling system.

    High pressure raises the boiling point of the coolant, so it cools more effectively even in very demanding conditions. That is why you need to replace the cap from time to time. They recommend changing it out every time you replace your coolant.

    Coming back to the overflow tank, it is needed because when the coolant gets hot it expands and the overflow holds the extra volume. The tank helps maintain the proper level of coolant and keeps air out of the system. You should never open the radiator cap or over flow tank when the engine is hot. This could lead to serious burns.

    What else do we need to do to keep our cooling systems working well? Well, there are the hoses that hook all of these pieces together. They’re obviously very tough to deal with the pressure and high temperatures. But they do get worn. Sometimes they get spongy from the heat. Sometimes they lose their connection to the radiator, water pump, etc. It’s a great idea to have your Wyoming service center inspect your hoses at least once a year and replace them, if needed, before they break.

    Bob & Dave’s Garage can help you check your cooling system and make any necessary adjustments or repairs. Give us a call at 616-532-7209.

  • Coolant Antifreeze Service In Wyoming Michigan

    You may know that most automotive failures in Wyoming Michigan are tire related, but do you know the second most common cause for vehicle failure? Nope, it’s not teenagers. It is the coolant system. But, if you take good care of your coolant system, it will take good care of you.

    A car’s engine creates a lot of heat – so much heat, that if it is not properly cooled, the engine can lock up, resulting in massive damage and repair bills. But when everything is working right, your engine operates at the proper temperature and all is well. Without antifreeze in your cooling system, the water could freeze and cause engine damage. This could be very expensive, not to mention inconvenient.

    The right mix of water and antifreeze protects the engine against damage from freezing and overheating. Antifreeze also protects the coolant system against corrosion that could cause the system to fail. The thing to remember is this: coolant system failure is very common, but it is also very easy to prevent. Your Wyoming service center knows the manufacturers’ recommendations, and can tell you when the coolant needs to be changed. They can also perform a coolant system service.

    Give us a call or stop by for a coolant service or checkup.

    Even the best antifreeze cannot completely protect the coolant system from harmful deposits forever. The anti-corrosion additives are used up over time, so the coolant must be replaced. A coolant service cleans out the system and replaces the old fluid with fresh coolant. A coolant system service is a low-cost way to protect against major engine repairs down the road. Prevention is the key. Be sure to watch out for the two main warning signs: if your temperature gauge is in the “hot” zone or if you get a message warning you to check your coolant. If you take a look under the hood, you will see the coolant overflow bottle. You can see there are lines that indicate the proper level of coolant … if your engine is cold – or if it is hot.

    You can add water or antifreeze to that bottle yourself, but be careful. First, you never want to open the radiator pressure cap. The steam could severely burn you. Second, try to get to your service center immediately if your coolant is low. If that is not possible, follow the directions in your owner’s manual. Third, remember that you need a proper mixture of water and antifreeze, or you will damage your engine. If you make an emergency addition to your cooling system, follow-up with your service center where they can make necessary corrections. Fourth, not all cars use the same type of antifreeze.

    You will need to check your owner’s manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. If you’re not sure, ask your service technician at Bob & Dave’s Garage for guidance.

  • Keep Your Cool In Wyoming

    Wyoming drivers rely on their car’s coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle 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 vehicle’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 Wyoming, the water in your engine could freeze while your vehicle is sitting out in the cold.

    So, if you remember your Wyoming 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 Wyoming.

    Keep Your Cool In Wyoming Whenever the vehicle 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 vehicle 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 vehicle’s engine is ruined and has to be junked.

    This is why it is critical that Wyoming drivers check coolant levels frequently and have their vehicle cooling system inspected for leaks. Also your vehicle 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 Bob & Dave’s Garage in Wyoming.

    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 vehicle cooling system components. Over time, the additives are depleted and the coolant just has to be replaced.

    Many Wyoming auto owners ask Bob & Dave’s Garage 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 Bob & Dave’s Garage or your owner’s manual for the right kind because using the wrong coolant can void the warranty for your vehicle cooling system.

  • Keeping Your Engine Cool In Wyoming Michigan

      />  

    The cooling system keeps our engine from overheating while you are driving around Wyoming Michigan. Its job is to move heat away from the engine. Let’s talk about the various components of the system and how they work to accomplish this.

    The radiator is the part most everyone associates with the cooling system. Coolant flows through the radiator which has fine cooling fins that draw the heat out of the coolant and dissipate it into the air. To make sure there’s enough airflow over the radiator, a fan pulls air over the cooling fins even when the car is idling.

    In some vehicles, the fan is powered by the serpentine belt. On others, an electric motor runs the fan. Electric fans turn on and off as needed. You may have heard the fan kick on shortly after you turn your car off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.

    Wyoming Michigan Radiator A hose connects the radiator to the water pump. The water pump pushes the water into the engine block. Now the engine block and cylinder heads have passages for the coolant to pass through without getting into the oil or the combustion chamber. These passages are referred to as the “water jacket”.

    While the coolant is passing through the water jacket, it absorbs heat from the engine on its way to the radiator for cooling. Between the engine and the radiator is a gatekeeper called the thermostat. The thermostat’s job is to regulate the temperature of the engine just like your home thermostat regulates the temperature of your house. It gets your engine up to the correct operating temperature and then keeps it from overheating.

    When your first start the engine, it’s very cold and needs to warm up.

    So the thermostat blocks the flow of coolant to the radiator. As the engine warms up, the thermostat starts to let coolant flow through the system.

    The final component I want to talk about is the overflow reservoir. This bottle is designed to hold some of the coolant. It’ll have a mark that indicates whether or not you have enough coolant. This is where you should add coolant if you just need to top it off.

    Caution: never open the reservoir or the radiator cap when the car’s hot. The cooling system is pressurized and opening them while it’s hot can cause hot coolant and steam to escape resulting in serious burns.

    Cooling system failure is the most common mechanical failure in vehicles around Wyoming Michigan. Your Wyoming Michigan service center can do a periodic inspection of the components for leaks, loose connections and weakening hoses.

    Your manufacturer has also specified a cooling system service interval. With a cooling system service, the old coolant is replaced with correct clean fluid that contains the additives required to prevent corrosion. The additives are depleted over time and you need fresh fluid for adequate protection. Your radiator pressure cap should be replaced at this service as well.

    The coolant system is a vit

    al part of your vehicle. It is also the second most common cause for vehicle failures.

      Even though coolant system failure is fairly common, it is easy to prevent.

    The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and

    is filled with coolant.

    The coolant draws heat off the engine and then goes into the radiator.

    Air passes through cooling fins to reduce the temperature of the coolant and then it’s back to the engine again.

    There are several ways for the cooling system to fail. Most common is with the coolant itself.

    Coolant is a mixture of water and antifreeze.

    The proper mixture keeps the coolant from either boiling away or freezing. Both of which can result in massive engine damage.

    Another very important coolant issue that is often overlooked is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can’t protect the radiator and o

    ther parts from rust, scaling and corrosion.

    Old coolant may still keep your engine cool, but it won’t protect it from corrosion.

    If you see a warning message to check the coolant or if the temperature gauge is in the hot zone your cooling system needs to be checked. It’s OK to add water or antifreeze yourself. But you need to be cautious.

    Remember four things.

    Remember, your Wyoming service center has the equipment to change your coolant quickly and inexpensively.
