Loose fan belt leaking head gasket faulty water pump Timing not right too close to TDC~~

Answer 2

Overheating problems tend to fall under two catagories, 1) lubrication, and 2) coolant system. If the engine is not recieving proper oil pressure, this could cause overheating. However, 9 times out of 10, it is a coolant system problem. If you are sure it isnt a thermostat problem (as it should probably be replaced first since it is the cheapest part in the system), then it could be one of several problems. Obviously, the first step would be to check your radiator fluid level. If it is really low, then there is a suspect leak in the system. If not, then it may be the water pump. Corrosion can cause a failure inside the pump, in which the impeller breaks free of the flywheel. If this happens, no coolant is circulating in the system, and the engine overheats. There could possibly be a blockage in the coolant system somewhere, but that would be a remote probability. I would guess it is a water pump problem. Also, I would check the front of your radiator. If there is a lot of stuff (like bugs, leaves, etc.) covering the fins, then there is a much less cooling effect, however, I wouldn't think this would cause overheating (although it could cause your engine to run warmer than usual).

Answer 3

Many cars today have an Electric Fan on the Radiator and it comes on at a certain temperature. Open you hood, with the car running see if the fan comes on. If, not, most times it a bad fan, but, it can be a bad sensor to the fan.
Another thing is the coolant. Are you having to add coolant often? After checking the fan, back the car up and look for coolant on the ground (Best done on a Driveway), if it leaking try to visualize where the coolant on the ground would have line up on the engine. Water-pump/Hose?
Then there a Plastic container where you add coolant. How this works; as a car gets hot the coolant expands and will overflow into the plastic container and then when the car cool the coolant is sucked back into the radiator from the plastic container. Sometime the hose to the container or the container itself can leak, you lose coolant and the car overheat.

Answer 4

have you checked your coolant level?
also, if your rad is clogged, you will not be getting proper coolant flow. they sell products that will help unclog your radiator, and it is fairly cheap way to test the problem.
if that doesn't work, have it checked out by a mechanic you trust, or that is recommended by family and friends
