Archive for August 2024Keeping Your Cool (Coolant System)Posted August 25, 2024 3:19 AMNo matter what the weather is like outside, your internal combustion engine expects to keep its cool all the time, even when it's really cold. That's because engines create the power that moves you to your destination by a series of tiny explosions of a fuel and air mixture. In turn, that generates a lot of heat in a small space. Your vehicle has a complete cooling system with a lot of different parts that work together to keep the temperature at a point where the metal engine parts won't heat up enough to warp. Its lifeblood is coolant, a liquid that circulates through the engine (and, in most vehicles, the transmission, too) through a series of hoses and tubes. In order to get rid of the coolant's heat, your vehicle has a part you probably recognize: the radiator. It does what its name proclaims: radiates heat. The radiator has a series of thin metal fins that coolant goes through, and when outside air passes over them, the heat is dissipated from the radiator into the air. The water pump (which is technically a coolant pump) is what propels the coolant where it needs to go. When there's a problem in the coolant system, it may because it's leaking somewhere. A few things to look out for are the temperature gauge heading into the hot, or red, zone, fluid leaks under your vehicle, or the sweet smell of coolant under your vehicle after it's been parked. If your vehicle has any of those signs, bring it in so we can check things out. A technician will inspect the water pump and hoses for any signs of leaks. They'll also look for leaks or holes in the radiator core or cores. One other potential trouble spot is the radiator cap that can sometimes fail to keep the required pressure in the radiator. Once the problems are fixed, they'll add the correct coolant and you'll be on your way. We want you to always keep your cool. Madison Automotive
Restore Your Get-Up-and-Go (Fuel and Air Induction Cleaning)Posted August 18, 2024 3:19 AMYou may have heard the old saying, "My get-up-and-go got up and went." If your vehicle's engine's fuel economy is noticeably worse, your engine is idling roughly or stalling or your vehicle's acceleration isn't what it used to be, ask your service advisor if you might need your vehicle's fuel and air induction systems cleaned. As the hours pile up on your engine, carbon deposits can build up. It's not unusual for some of the impurities and additives in fuel to leave behind a black residue that eventually will negatively affect your fuel economy and performance. Maybe you're noticing your engine is harder to start, you hear knocking or pinging in your engine and your vehicle just doesn't have the pep it used to. While it's a sophisticated process with a lot of components, a gasoline engine essentially produces power by drawing in air from the outside and mixing it with fuel in the cylinders where this blend of fuel and air is ignited by spark plugs in synchronized explosions. The fuel and air enter your engine through the fuel induction system and air induction system. Because of things like high operating temperatures and impurities, carbon in the fuel can leave behind dark, sooty deposits in the fuel induction system such as the fuel injectors and the throttle body. These and other residue reduce your engine's efficiency and performance. Our service center can use special fuel injector cleaners to remove those deposits from your engine. The technician may manually clean some of the deposits and also put a fuel additive in the fuel tank that will get rid of other deposits that are still in the fuel system Keeping the air induction system clean is also important. A technician can use a liquid cleaner specially designed for the job. Not only can this improve your fuel economy, it may also reduce exhaust emissions and help your engine last longer. Most gasoline now contains detergents that help reduce or prevent these problems, but direct injection is now being used in more vehicles that are more susceptible to clogging. Ask your service advisor if your vehicle could benefit from fuel and air induction cleaning. Madison Automotive Keeping Your Cool (Coolant leak repair)Posted August 11, 2024 3:19 AMIf there’s one thing you should pay attention to with your vehicle, it’s the temperature gauge. It’s the one that may say C---H (that means “cold---hot”). Or maybe yours has a picture of a thermometer on it and a blue and red zone. If you see the needle heading farther to the “H” or red area, that means your vehicle’s engine is running hotter than it normally does. One of the most common causes of an engine running hot is a leak in your cooling system. Maybe you’ve seen puddles of coolant under your vehicle, or you’ve smelled the coolant, either inside or outside your vehicle (it has a sort of “sweet” or fruity smell). That’s your engine giving you a warning signal that it’s time to head over to your repair facility to find out what’s going on. Your vehicle’s coolant can leak for several reasons. You may have hoses that are deteriorating (heat and age take their toll). It’s possible the pump that circulates coolant has developed a problem (seals and bearings can fail from heat and wear). You may have something as simple as a bad radiator cap. Or your radiator or heater core may have holes in it. If your coolant is leaking out, this can cause serious damage to your engine if you just let it go. Your engine could get so hot that some of the metal parts start to warp. Sometimes, your coolant can start mixing in with your engine oil. That can result in a very expensive repair if it gets to that stage, so have it checked out before that happens. A technician will visually inspect your coolant system, including the reservoir tank, check hoses and fittings, test the water pump, and also may pressure test the radiator. When the problem or problems are found, they will replace the necessary parts and get you back on the road. When it comes to a coolant leak, finding the cause can be tricky. But it’s important to catch a cooling system issue in time—before your engine sustains more serious damage. Now, that’s pretty cool. Madison Automotive | ||
