It could be the thermostat. Open up the radiator cap when it is hot and see if the water is flowing in the radiator. If it is not then it may be a thermostat.
Take your thermostat out and put everything back together, run your car without a thermostat... If your car no longer overheats, replace your thermostat.
Your thermostat is stuck closed. you will need to replace it. The thermostat controls the circulation through the radiator - when the engine heats up the thermostat is meant to switch circulation from just-engine to engine+radiator. Sounds like this isn't happening.
check your radiator. is it clean or does it need to be replaced? a simple cleaning cured my problem.
Check that the coolant fans are still working, then check out the water pump.
You have not bleed the air out of the system after you installed the t-stat, causing the heater not to work and the engine to overheat. Use a coolant filler that screws into the radiator and get the air out
did you try replaceing the thermostat or radiator or even check the hoses
Most likely it is a bad thermostat. The switch on the radiator fan could also have failed.
check you water (coolant) level, make sure thermostat is working, radiator leaks, sensor problem
Removing the thermostat can actually make an overheating problem worse. I would check the radiator fan.
Could be the water pump is not working properly.
Change the thermostat. lol. Simple but the water pump wont work if the thermostat is stuck closed. Good luck. Kyle
dose the electric fan run if not check the relay if it runs check the water pump
Try taking the thermostat out completely, then see if it still overheats. If so, your only other problem has to be a bubble in the system and it needs to be burped. Took me about an hour to get a stubborn air bubble out!
have the engine timing checked. if the timing is wrong the engine will overheat, are you loosing coolant?is the fan working, is the water pump working?
it has a cracked head The above answer would be an extreme condition to cause this problem. Usually a car overheats because of either low coolant level or a stuck or bad thermostat.
The top radiator hose is above the thermostat. If the top radiator hose is hot, the thermostat is opening. The thermostat is not the problem. Perhaps the radiator is clogged up or the water pump is bad. Look elsewhere.
you might want to check for a blown head gasket or a cracked head or block. espically if it loosing water out of the radiator with out leaking on the ground.
when overheating occurs at highway speeds the cause is usually. a radiator or coolant circulation problem, Check for a restricted or clogged radiator.
Absolutely. I would definitely replace this. You can check this by making sure that when you remove the thermostat it is cold and then dropping the thermostat into a bowl of boiling hot water and see if it reacts..... if it doesn't then that's the problem! If it does then flush the coolant system through with some radiator flush and then flush through with clean water before renewing antifreeze and water.
If your radiator isnt leaking and car is having a over heating problem and coolant spewing out. Chances are your thermostat needs replaced. possible the radiator needs to be flushed. But more likley its thermostat
check your fluids it is probably low on antifreeze and if it still does it change your thermostat that should fix the problem
Radiator plugged or restricted? Cooling system airbound? Water pump not circulating coolant? Radiator cap defective? Radiator hoses collapsing under pressure? Defective gauge/cooling temperature sensor?
It depends on the condition in which the vehicle overheats.If it only overheats when you're in traffic or at a stoplight, the problem MAY be that the radiator fan isn't working properly.If it overheats when you're on the highway or under normal driving conditions, it COULD be any of the following:Thermostat. A sticking thermostat can either stick closed, in which case the engine will overheat immediately or it can stick open, preventing the engine from heating up to normal operating temperature. Sometimes a thermostat will sometimes stick open and sometimes stick closed.Radiator. A blocked radiator will cause an engine to overheat rather quickly. A '97 is old enough that the radiator can be blocked internally, especially if the coolant has not been properly maintained.Water pump. If the vanes of the water pump have worn out the pump may not be able to move enough coolant to keep the engine cool.Head gasket. If the engine has EVER been significantly overheated it could have damaged the head gasket. A damaged head gasket usually causes the coolant to blow out the coolant overflow.Cooling fan. A cooling fan problem can be caused by either an electrical problem (sensor, fuse, switch...) or a faulty fan motor.If the problem is a bad thermostat, replace it with a new one.If the problem is a blocked radiator, you CAN take it to a qualified radiator shop and they can often clean it for you.If the problem is a worn water pump, the only solution is to replace the water pump.If the problem is a faulty head gasket, you'll need to have the head removed, resurfaced and replace the head gasket.If the problem is the cooling fan, you'll need someone to trace down the exact nature of the problem.
