How does the coolant system in a car work?
The car’s coolant system works by circulating a coolant and water mixture under pressure through pipes through your engine and radiator, thus cooling the engine. The temperature of the coolant rises as the car runs and the coolant expands so any excess coolant in the system moves into a reservoir tank by way of rubber hoses.
What causes a leak in the coolant system?
An internal leak could be caused by a leak in the head or block or perhaps a leaky head gasket which lets the coolant escape its system. An external leak is the type of leak which is most easily diagnosed. More often than not, when you have an external leak, the coolant escapes and your car quickly overheats.
Why is there a puddle of coolant under my car?
Refer to your car’s manual for the proper cap and pressure. An internal leak won’t cause a puddle of coolant under your car. Instead, it will be noticeable when your coolant level does not stay constant and you find that you need to constantly refill the tank to keep your engine from overheating.
What does that hissing noise from my AC mean?
The compressor hissing or shrieking is a serious situation: it means the pressure inside the compressor is too high. If you hear hissing, or worse, shrieking, coming from your compressor, turn off your air conditioner immediately and call a technician; do not restart your air conditioner until it has been looked at by a professional.

Your car’s cooling system works by pumping fluid through the engine, where it picks up heat. The fluid then moves to the radiator, where it cools before starting the cycle again. As such, if you have a car leaking coolant, you must act quickly to find and fix the coolant leak.
What does that hissing sound from my air conditioner mean?
A Hissing Air Conditioner. A continuous hissing that sounds like gas escaping from the AC is something is usually a warning noise. It can mean a number of different issues are occurring: Refrigerant leaks: Escaping gas might be the actual problem.

Car cooling systems rely on a sealed network of hoses to pump coolant/antifreeze around an engine. These hoses are arranged in a sealed loop, which allows a smooth and constant flow of coolant/antifreeze to reach components including the head gasket, cylinder heads and engine block – keeping the engine working at the right temperature.
What should I do if my coolant level goes up?
If the temperature gauge rises, the best way to temporarily deal with it is to turn the heater up full and the air conditioning on. Try to get into the habit of regularly checking your car, including the coolant level and fan. Modern cooling systems shouldn’t really need topping-up between services.
When does coolant come out of the radiator?
When the car is moving beyond 30 mph on a level surface and the day isn’t too hot, there’s enough airflow through the radiator w/out the fan. Watch the temp guage on the dashboard. Usually the fan is set to kick on about 1/2 to 2/3 of the way up the dashboard temp scale.
What’s the boiling point of coolant in a car?
The point at which coolant/antifreeze boils depends on the quality of the product itself, and the pressure maintained inside the cooling system. At normal operating pressure, Prestone Coolant/Antifreeze has a boiling point of 129°C, and a freezing point of -37°C.
Where does steam come from in a coolant tank?
Most of the time when you see “steam” coming from the overflow tank, it’s due to higher than normal or overheating problems within the coolant system. As you know, when coolant and water reach “boiling temperature”, water evaporates into steam. The coolant overflow tank has open space, where hot “vapor” has a chance to turn to steam.
What is the problem if my coolant reservoir is steaming hot?
COOLANT RESERVOIR IS STEAMING HOT chevrolet 2004 l4-2.0l What is the problem if my coolant reservoir is steaming hot? My car has 230000 miles. My car has a manual transmission. Hi there. Most of the time when you see “steam” coming from the overflow tank, it’s due to higher than normal or overheating problems within the coolant system.
What should I do if my coolant level is high?
Refill your coolant, making sure to bleed any air out of the system, replace the plug and top off your coolant reservoir. Start your engine and drive carefully to test whether there’s any air caught in your system. Continue to inspect your coolant reservoir for any signs of a leak. Never refill your coolant when your engine is hot.
What does it mean when your coolant tank overflows?
As you know, when coolant and water reach “boiling temperature”, water evaporates into steam. The coolant overflow tank has open space, where hot “vapor” has a chance to turn to steam. If your car is overheating, this is something that should be inspected by a local mechanic. If the temperature is good, it typically does not indicate a problem.
