Depends on how hot it got. You can blow a head gasket. The first check is to see if there are combustion gasses getting into the cooling system. Take a sample of the coolant and go to the local radiator shop and request that they analyze the coolant for the presence of hydrocarbons. If they are present then it is most likely that you have a blown head gasket. Another check is to look at the oil of a warmed up engine. The antifreeze in the oil will whip it up into a frothy brown mixture that looks like a milk shake. If it looks like chocolate mousse then you probably have a blown head gasket. Another check is to fill the cooling system to the brim and remove the radiator cap. Do this when the engine is cool. Start the engine and race it. If there is a compression leak and the gasses are going into the cooling jacket then the gasses will displace the coolant. Since the cap is off the coolant will be pushed out of the radiator. You probably have a blown head gasket. You may also smell coolant at the exhaust pipe. It will smell sweet.
In brief, you will blow the engine.
you are most likely leaking coolant and if your car should be overheating in a short period of time.
my car isn't steaming only in drive but not overheating.
If you run it too hot the engine will give out, and it will NOT work again. You're going to blow the motor, basically.
Your car is overheating when idle because there may be a lack of oil or water in the engine. It can also be a problem with the engine itself. If your car is overheating, simply contact a wrecker or a road assistance company. The police are also available to assist you.
You should not buy a car with overheating problems. This means that it will not serve the purpose and will develop other mechanical problems.
your car is broken
one reason this may happen is as simple as the cap on your cars coolant reservoir is stripped or improperly screwed on. when this happens it doesn't allow pressure to build or hold.
It means the car is overheating.
There are several reasons why your car may be overheating. Check the thermostat to be sure it isn't stuck. If the car revs up and down, the timing may need to be adjusted.
95 aurora runs normal temp,but coolant res low with dash signaling low coolant.not overheating but,reservoi low.driping coolant slightly after a run.????????????????this happens starting with cold car and full reservoi.any ideas?
Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.
