Thanks.
But I think ta my fan. They are not coming on at all. I change the switc on the thermo housing. And the thermostat and I even got water pump.
The fans are not working. They turn on when I turn on ac. But that's about it.
I jump the wire yesterday and the fan works
what can I do now? Is it the black box thingy down next to the ecu? (fan module control)

are you having to add coolent to it at all bc i had a heater hose leak that i couldnt see or have it be wet but it smoked like a b**ch

preludeh2394

no there is no leak and no smoke. just that the stupid fan isnt coming on lol.
but thanks for the offer of advice; i will check again incase there is a leak, however my coolant level does not seem to rapidily decrease

preludeh2394

come on guys help me out
my car still over heating. i was heading to school like 30 miles away. the guage shows its over heating, but as soon as i pull over and i turn it off and than back on it goes back to normal operating temperature and drives fine all the way. is it something elelctrical?
i change the sensor on the thermostat already. and there is no leak. and there is significant amount of coolant.
however the fans are not coming on. (does both fan come on or just one)

1 fan is supposed to come on, 2 only come on when you run the A/C.

Does it only overheat in stop and go traffic or is it overheating while you are cruising on the highway too?

Did you do the water pump or a shop? If a shop did it, did you get back your old water pump? I ask because the same thing happened to me. The water pump fins rusted off and one got stuck in my motor and we thought we got them all. Everything ran fine on it but coolant would steam out the overflow. What about heat? Is it hot or colder than it used to be? It could be a blockage in your heater core. If you want to run the fans all the time, run them to acc wire.

preludeh2394

it most likely overheating at slow traffic and stop lights. probably cause the fan is not coming on.

sometimes it over heats on the highway but it drops back down quickly

preludeh2394

i did it at the shop. and i dont have any leak of coolant anywhere either.
i just order a radiator today i m gonna put it in and see what happens

preludeh2394

ok just put new radiator in and it didnt help.
bright side is that now at least i have new radiator.
still having same problem/symptoms
drive for a while temmperature gauges goes up.
i drove it after putting new radiator in and htan let it sit for a while the temperature goes than it went back down again. didnt do anything either. it just went up and than i kept watching the temp gauage and it went back down again.

Have u checked for the headgasket yet? I think you've eliminated EVERYTHING else...

do you know how i can check if it is the head gasket that is causing the problem

i<3myLUDE!

Have u checked the cooling fan relay? I think I might have an extra one laying around.

preludeh2394

the relay under the hood fuse box right? yeah i have check. and if the relay was bad would the fan still come on when i turn on ac? cause my fans still turns on when i hit ac
