O/T......overheating

i know that this is way off topic, but i figured maybe somebody here can help anyway. i have a 95 ford windstar van with a 3.8l v-6, that has a little overheating problem. i have replaced the thermostat(2x), and just replaced the water pump. it still wants to run on the high side of the temperature gauge. i have checked this thing over very well and it has left me scratching my head. no signs of blown head gasket(s) or any thing else that can cause this, unless i am missing something. any thoughts or ideas that may be the problem? any help will be greatly appreciated.

Re: O/T......overheating

Have you done a pressure test on your system? This will tell you if you have a leak or if your hoses are collapsing causing restriction in coolant flow. I like to replace mine every couple years regardless how they look.

How about the fan...does it turn easy by hand?

Maybe your temp sensor is bad...do a resistance measure on it.

Good luck

Re: O/T......overheating

flushed the heater core today and it did great for a while then BAM!!!!!!! all of the sudden it started again. this thing is like a yo-yo. the temp gauge will go up really high then all of the sudden it will go back down. which leads me to believe that a hose is collapsing and restricting flow. i have also replaced the radiator cap so i know that is not it. i REALLY appreciate the help so far. i hope to get it fixed soon.

Re: O/T......overheating

I'd possibly lean toward what muddybronco is saying. Are there any other signs of overheating other than what the gauge is saying? You could buy a cheapie aftermarket sensor and just drop it in the radiator while its running. bring it up to temp and see what the extra one reads. Or for a few bucks just replace your sensor and see what happens. Most likely the sensor is under $20.
