There is no sure way to know until you take the thermostat out and check it. After removing the thermostat, you can test it by submerging it slowly, with a tool in boiling water. You can then see the thermostat open up. If it does, this is not your overheating cause. If it does not, you need to purchase a new one. Install the new one and you will find out if that was the problem.
are the cooling fans coming on
I would start with checking your thermostat and thermostat housing. See if its regulating. If it is not replace the thermostat.
It MAY help with the overheating problem....but you really need to find out why it's overheating. Blown head gasket, stuck thermostat, bad water pump, fan not coming on, etc.
Could be the water pump is not working properly.
Check the thermostat first. I had an intermittent overheating problem on my 02 for almost a year, changed the thermostat and it never happened again. If that doesn't work, secondly I would check the water pump.
Check the water pump. If the thermostat is working properly then the next common problem would be a bad water pump.
Your radiator might have a small pinhole in it, causing it to not build up pressure.
I had a VW Jetta that had a problem with overheating. It ended up being the thermostat had gone bad so the fan never "kicked on." A car can over heat if there isnt enough antifreeze in the radiator or a bad thermostat or if your fan isnt working properly or is bad
is it leaking anywhere? Can you be more specific other than overheating. I had the same problem 2 weeks ago. I fixed it.
Take your thermostat out and put everything back together, run your car without a thermostat... If your car no longer overheats, replace your thermostat.
my jetta keeps overheating so i replaced the thermostat hoping that was the problem but know there telling me it might be the water pump check it out maybe its that
Did you make sure that you are putting the themostat in correctly? If you put it in backwardthis can sometimes cause this problem.
Thermostat may not be opening
Overheating can be caused by several things. Make sure that the cooling fan comes on when its supposed to. Make sure that air can flow through the radiator cooling fins. Insure that the thermostat is not stuck shut, the water pump is working, and that the coolant is flowing properly. One of these would be the most likely problem.
IF YOUR CAR IS HEATING UP(OVERHEATING) AND YOU STILL DRIVING IT, A FAULTY THERMOSTAT IS THE LEAST OF YOUR PROBLEM.
problem with timing belt 0r car is overheating check thermostat....bad gas /water in gas
Inoperative radiator fans, bad water pump, failed headgasket?
Depends on why its overheating. IF the Radiator fan is not kicking on, then there are several things you can check. One is that the AC system is working properly. Unfortunately, Ford tied in the AC system to the cars cooling system (overheating). And without the AC System working properly you might have to wire a toggle switch directly to the fan, with a fuse link on one side, to be able to manually turn on the fan when the car reaches temperature. IF the AC unit is working properly there are 2 sensors. One is on top of the thermostat housing, and actually is in the housing. The other is in the engine block right next to the thermostat housing. IF either of these is not working properly, then the fan unit will not come on. If that is not the problem, you may have a blockage somewhere, and need a serious cleaning of the radiator and/or engine block.
Removing the thermostat can actually make an overheating problem worse. I would check the radiator fan.
If it is running hot then you need to service the cooling system. Drain and flush the radiator, replace the thermostat, check the operation of the water pump, see if the cooling fan is operating properly, and make sure the belts are tight and not slipping. Another possibility is a blown head gasket. Removing the thermostat is not the answer to an overheating problem.
It depends. I Just fixed an overheating problem on my 98 contour. I replaced the thermostat (did not solve the problem). I then tested both thermostats (I put them both in a pan of boiling water and they both worked fine. Quick Check: When you put the heater on in side the car, if it does not blow hot air, most likely the problem is a blown water pump. Mine was in pieces when I looked at it. I replaced the water pump and everything appears to work fine now.Hi, I had the same problem in my 96 contour with the 2.0. I couldn't find the source of the leak and decided to put a bottle of Block Fix in the engine. You have to follow the directions to the letter for it to work properly, but it should fix your overheating problems as it did mine. I also am running mine without the thermostat and have been for over 1 year now and have had absolutely no more overheating problems. Contours, as mine does, tends to run a little bit hotter than most other vehicles, but its ok. Hope this info helps anybody who is experiencing this problem with their Contour. Mine runs like a champ now!!
Could be the head gasket. Very common problem with this engine and model year Windstar.
By finding the cause of the overheating. It is normally, bad thermostat, bad water pump, clogged radiator, either internally or externally, a defective cooling fan, or defective cooling fan relay.
Check to make sure you have the correct mixture of anti-freeze and water because anti-freeze also helps with overheating too. If you still have a problem check your thermostat. It could be stuck closed and may not be opening.
