I replaced the switch/sensor on the thermostat housing and both fans kick on when I turn the A/c on but the stupid fan wont turn on to stop the car from overheating......WTF!? Now what are my options.......?

 

Did ya replace the thermostat too? Did ya flush and fill the Rad fluid?

 

I replaced the thermostat today also, i filled it with fluid and let it bleed out or actually left the cap off so the bubbles would come up out of the radiator. I dont see how that would affect the fan not turning on though.

 

because if the thermostat doesn't open it wont let the water circulate around the fan switch and the fan wont switch on

 

well i replaced the thermostat, and i just went out and cracked that little nut thing and all that came out was fluid.....closed it up and still overheating. i cant get that damn fan to turn on for the life of me.....i pulled the relay out while the a/c was on and it cut the passanger side fan off, and when i put it back it came back on so im thinking the relay must be good......any other suggestions?


I really want to figure this out before I have to take it to a shop and get raped on the diagnostic.......the want $70 just to tell me whats wrong with it and it will probably only take them 5 minutes

 

next thing to do is to make sure there is power going to the fan switch, the easy way to do this to unplug the connecter from the switch and bridge the wires and if the fan comes on the you have power

 

i jumped the connector that runs from the wiring harness and both fans kicked on.. someone told me the switch might be bad so im taking it back and getting another one.......i also dont know how to test if this one is good or bad......any tips/tricks?>

 

I havent done anything to the car since i bought it other than what im doing now. so when I use the multimeter it should read 0 until the water is almost boiling right?

 

Ok, now the battery light is fixed........tightened the alt. belt.
Temp is sort of fixed.........car will get to about 3/4 when sitting still then the BOTH fans kick on.....Car doesnt get hot when I'm driving it, only sometimes when its sitting still for a minute or two. Wierd.......

 

the one I have is like two probe things, its a big cylinder then steps down to a smaller skinny one. I will take a pic tomorrow. Also I noticed when I turn the headlights on and drive the car likes to run hotter, like within 2 minutes the temp will jump up........earlier I had the lights on and the fans were running but the temp gauge was almost to the red.....wtf is up with that?

 

anyone know why the temp gauges jumps when the lights are on?

 

Well before the fans started working there was white smoke comming from the radiator.....I just drove the car around and let it sit and idle for about 5-10 minutes, went back out and the gauge was setting steady at half way. I put some more fluid in the rad. last night to top it off and drove it around this morning to get it circulated through the system to make sure its filled. I can turn the lights on sometimes and the gauge goes up, then when i turn them off it goes right back down.......not instantly but it does go back down...mabe i should just take it to a shop already

You have a blown head-gasket. Whenever there's any gases coming out of the radiator, you have a leak in your head. Trust me, replace that and you'll never overheat again until something else breaks . Also, if your fan doesn't work spend a few bucks to get a slim electric fan, it's worth your bucks to keep your car reliable. Good luck!

 

the headgasket was replaced 60k miles ago......I dont think its that.......last night I drove the car to work no problems, came home, no problems.........turn on the high beams it gets hot, turn them off it goes back down.......then my g/f gets in the car with me and we go to the store........come home and it gets hot, hotter.......then i just turn it off...this is pissing me off
