What does the thermostat on a car do?
The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.
Check engine light comes on when key turned on but not coming on once engine is turned on why?
It is not supposed to be on when engine is running unless there is a problem.
Can a loose coolan cap cause engine to overheat?
it will allow coolant to leak ut. once the coolant gets low then the vehicle can over heat
How does a pressure coolant tant work?
It collects the expanding coolant that is heated by the engine and recycles it back into the coolant system once it loses enough heat. The radiator overflow tank works in conjunction with the radiator cap to protect the engine and prevent coolant loss due to overflow. Source: Quora.com
Where on the engine block of a 1987 Nissan maxima are the coolant system drain plugs and after you flush the system do the drain plugs have to be replaced?
Ive never heard of draining coolant plugs except on a diesel engine . Once you drain the coolant and flush the system it should be fine
How do refill the coolant on a Saturn sl?
The plastic coolant reservoir on the fender feeds directly into the coolant system. Just add coolant to the reservoir and if you have drained the coolant or otherwise emptied the system, you may need to check the level in the reservoir after running the engine, or more accurately, after the engine has cooled. Once the coolant level has stabilized, just check it periodically to make certain that the coolant level never gets too low.

Is there relation between stalling engine and blue coolant light My 2001 vw beetle drives rough even at low speeds when the blue coolant light is on. Once the light is off it drives fine?
blue is when the engine is cold & when it turn off it means that the engine is at the right temp..
Does the thermostat control the heat in your car?
No, the thermostat controls the temperature of the engine coolant. As long as the coolant temperature is below the thermostat set-point, the thermostat remains closed. Once the temperature arrives at the set-point, the thermostat starts to open, sending heated coolant through the radiator. The radiator then cools the heated engine coolant and the water pump forces the coolant back through the engine. The heater control valve allows more or less of the engine coolant through the heater core. Since the coolant should be very near the set-point temperature of the thermostat, you should be getting hot water through the heater core to warm the inside of the vehicle. The engine coolant is there to keep the engine from melting down or from breaking metal parts and burnng off the oil. It just happens that the heated coolant is useful to warm the inside of the vehicle.
How do you drain coolant from an Arctic Cat ATV 650 v2?
To drain the coolant from an Arctic Cat ATV 650 V2, first ensure the engine is cool and remove the radiator cap. Locate the coolant drain plug, usually found at the bottom of the radiator or engine, and place a container underneath to catch the coolant. Remove the drain plug to allow the coolant to flow out completely. Once drained, replace the drain plug, and refill the system with fresh coolant as needed.
What is a coolant heater on a diesel engine?
You're thinking of a block heater. It plugs in to shore power, and energizes an element attached to the engine block (some have dual elements, and the second one will go to the oil pan) to heat the coolant in the water jacket so that it doesn't freeze. In turn, once the engine is running, this heated coolant will get circulated to the rest of the system, and begin thawing out the remaining coolant.Although a block heater doesn't actually circulate the coolant when the engine is at rest, there is a type available which is essentially an electric pump which will pump coolant through a heating element and back into the cooling system... I've only ever seen it on really specialized heavy equipment.
What does the thermostat do in a 1994 Honda Accord?
Its job is to block the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions.
