Better check your fan clutch, then maybe your water pump.
it can..rain has NOTHING to do with your radiator or the thermostat
check your fan clutch if its weak it will overheat
im having the same problem with my 1994 I've replaced the heater core,thermostat,radiator,i checked the coolant, and it's not over heating or nothing and still no heat lol
You need to have it tested by a knowledgeable mechanic. They use some kind of blue liquid that should stay blue during the test. If it turns yellow, you have a problem. If your car is running hot and nothing else has solved the problem (thermostat, radiator flushed, leaking radiator, hose or pump..., you should have it checked.
If you are unsure if it is heating because of a water pump or a thermstat, you can find out by removing the thermostat. If it still heats without a thermostat, then you know it is the water pump. Without a thermostat, the water flow has nothing to cause it to heat unless the water pump fails to circulate the water. No circulation of the water would cause the over heating.
An automobile's radiator fan will switch on and off during normal operation of the vehicle, and sometimes after the vehicle is shut off. The fan is controlled by a thermostat that regulates the temperature of the coolant in the radiator. When the coolant rises above a certain temperature, the thermostat switches the fan on to cool the radiator until the temperature drops below its limit and shuts off. The fan turning off and on is a normal part of the car's operation and is nothing to be concerned about.
If you do not have any external leaks, a head gasket is most likely.
check engine timing sticking brakes can also cause overheating
Yes. The thermostat just helps the engine run at a more efficient temperature. Without a thermostat, all possible coolant circulates through the radiator and keeps the engine running at a low temperature. It wastes fuel and is hard on the engine. Also, when there is no thermostat the coolant is sucked so hard that the radiator hose can collapse, then NOTHING is circulated and the engine overheats until the internal pressure gets great enough that the hose expands again. In general, it's not a good idea to run without a thermostat, but it is done all the time.
if your thermostat was bad your engine will over heat but it has nothing to do with the fan,fans are driven by a diffrent mechanism. try checking your thermostatic switch/ heat sensitive switch or sensor, located somewhere in the cooling system(radiator,engine block or thermostat housing) which is the one that tells the fan when to come on.(only electric fans)it may be faulty wiring
i had the same problem in my 96 grand-am i actually replaced the radiator, coolant overflow tank, and thermostat before it stopped. Check your coolant overflow tank and check for cracks and whatknot. If nothing else check the fan and make sure all belts are in proper motion and stuff. hope i was some help
Nothing to do with the thermostat, everything to do with changing the coolant on the recommended* basis (or sooner). The "green" coolant is NOT long-life and recommended to be changed more often than the "yellow". But even the 'long-life' requires changing no longer than 5 years. NOTE: Both these coolant types are mentioned in the Owners Manuals.
