are the cooling fans coming on
Your radiator might have a small pinhole in it, causing it to not build up pressure.
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
Inoperative radiator fans, bad water pump, failed headgasket?
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
Could be the head gasket. Very common problem with this engine and model year Windstar.
I would start with checking your thermostat and thermostat housing. See if its regulating. If it is not replace the thermostat.
i would have replaced water pump long before replacing radiator. also check engine oil to see if it has engine coolant mixed in.if it has then the problem is more likely to be a bad head gasket
Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.
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.
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.
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 your coolant levels and make sure it is up to level and decent looking...Coolant (in this case) should be a nice Lime green. Engine Thermostat is probably the most likely cause of overheating...It should be replaced if you haven't already.
Same problem turned out to be a hair line fracture to the head!
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.
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.
I have already replaced the radfiator,cap,thermostat and confirmed water pump works. cools fine w/o radiator cap ,pressure builds and temp. rises when cap in place.
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!!
Did you make sure that you are putting the themostat in correctly? If you put it in backwardthis can sometimes cause this problem.
Yes it can cause it to overheat but first check your thermostat. That would be the 1st cheapist thing to do before you did anything else. I got an 85 regal(overheating) and the thermostat or the heater core is the problem im getting them both replaced tomorrow and will let know of how it runs.
Thermostat may not be opening
The gauge reading has nothing to do with the overheating problem. Misleading and irritating yes, but not involved in causing it.See "Related Questions" below for discussion on replacing the temperature sending unit, and also a comprehensive diagnostic guide for overheating problems.
Check the relays in the small relay box UNDER THE HOOD. There is a relay that will go out that runs the cooling fan when the car reaches a set temp. If that fan does not come on then it will cause the car to overheat. If that turns out to not be the problem have a mechanic look at whether the head has warped from overheating.
Have the water pump checked. My 99 had an overheating problem; guage would go up and sometimes engine would stall. It turned out to be the water pump.
