The base model 1995 Chevy Cavalier came with the long-used 2.2-liter four-cylinder engine and a five-speed manual transmission. The cooling system on your 2.2-liter has a total capacity of 10.7 quarts, so even with a small coolant leak; you can quickly lose enough coolant to cause overheating and damage to your engine. Because your cooling system maintains a pressure of 15 psi during engine operation, it is possible you’re losing coolant only when the engine is running and shortly after until the pressure is lost through the breech. Tracking down your coolant leak can be tricky, but the biggest thing…
Removing your engine’s oil cap to find the underside clogged with crud is never a good sign, but it need not indicate a deformed head gasket and the top-end rebuild that necessitates. Even without constantly dropping coolant levels, any milky, mocha-colored creamy substance on the underside of the filler cap is the result of moisture becoming emulsified -- mixed in -- with the lubrication oil. Discovering and fixing the cause should be a priority.
The smell of coolant coming from your refrigerator may concern you. Coolant or refrigerant leaks in refrigerators are rare, though, so inspect your refrigerator to determine if this is really your problem. You're likely to find that it's a much simpler problem.
The coolant in a properly functioning refrigerator remains in a pressurized state at all times. Modern refrigerators use R-134a, an ozone-friendly refrigerant, as its coolant. A refrigerator uses a compressor to force coolant through two coils and a set of coolant lines. Vibration-caused leaks usually occur where the coolant lines rub against the refrigerator's housing, defrost bulb or around the coolant line's mounting brackets. Technicians use a refrigerant leak detector with a heated diode sensor to locate the refrigerator's coolant leak.
Testing for CO2 in a car radiator is prompted by the suspicion of a head gasket leak. Most of the time, head gaskets develop leaks due to engine overheating. The head bolts are steel while the cylinder head is either cast iron or, most commonly today, aluminum. Being dissimilar metals, when the engine overheats, the head bolts will expand more rapidly than the aluminum, resulting in a warped head. The head gasket, having unequal pressure upon it, will fail at one spot or another. A failure causing a leak can originate from the water jacket to the oil pan, resulting…
Coolant, also known as radiator fluid, keeps your engine from freezing in the winter and from overheating in the summer months. You must flush and replace your car's coolant occasionally. The radiator has a drain plug that, when removed, allows the fluid to empty. You can then fill the radiator with fresh new coolant after replacing the drain plug. Coolant also protects the engine against corrosion. Note that ingesting coolant can cause death in humans and animals.
Yes. If your engine is overheating and you've got a bottle of water in your car, don't hesitate to pour the water in. It may help you avoid seriously damaging your engine.
Part of owning a car is maintaining it so it continues to run. Whether you're adding coolant as a proactive measure to avoid engine troubles, or you have found your car overheating due to lack of adequate coolant, putting coolant in a car is a fairly straightforward task. Using safety precautions and the right tools, you'll be able to change the coolant in your car with little effort.
Heat is the biggest threat to your car's engine. Hundreds of moving parts and burning fuel create a high-heat environment that can quickly deteriorate unprotected parts and lead to costly repairs. The radiator is what controls the heat, carrying it from the engine via coolant and dissipating it into the air. When a radiator is no longer able to properly perform this function, the problem can manifest itself in a few distinct ways.
Among the critical liquids needed to keep a car running, engine coolant comes into play when temperatures are in the extreme. Sure, you could technically use water as a coolant, but it won't last as long and it enhances corrosion in engine parts. Coolant solves both problems and is formulated to protect your engine's functions. However, as a product it does have its limitations.
A vehicle's radiator helps to keep the engine from overheating. It contains a mixture of water and coolant, and if it is cracked, your car can break down. A bad radiator can also lead to engine damage. Several things can cause a cracked radiator.

The proper coolant level in a car keeps the cooling system from overheating in the summer and from freezing in the winter. Equally importantly, the coolant retards rust and corrosion in the engine and radiator and lubricates the water pump and other parts. Periodically, you'll need to check the concentration level to be sure it is effectively doing its job. Here's how calculate and adjust the proper concentration.
Due to the potential for high lead content, you must take extra care to dispose of car coolants and antifreeze products properly. First, you must determine whether or not the coolants you want to dispose of are considered hazardous waste due to lead content, and then select a safe method of disposal, or recycle the car coolants.
It is important to check your car for coolant leaks regularly, since a cooling system that isn't functioning optimally can lead to serious damage to your car's engine and the costly repair bills that will inevitably follow. If you know what to look for, it is relatively easy to check for car coolant leaks and take action to fix the problem.
