well, i was driving my gf's 92 teg yesterday and I realized the engine temp was at H(the red zone).... i quickly stopped the car, turned it off and popped the hood... there was some coolant near the battery side, and some even got on the hood... but on tht side only! went to a shop, and they KINDA fixed it... pretty much, the guy hosed down the radiator exterior, opened the radiator cover, started the car and put water into the radiator (while car was running).... did tht for a few times, and the temp needle started going down...

it stayed down the whole day after tht, but everytime I shut off the car, the cooling fan still runs... and this morning, the car won't start... i'm guessing the fan drained the battery dry... i'll try and jump the car and see if it's the battery... but any idea wat's up with the radiator? i checked this morning, and there was no leak at all... and i'm pretty sure it's not a thermostat too.... thanx!

 

check the top of the radiator for a crack. It will be on the edge facing the engine. Fill er up good, start it, and as it warms and builds pressure the crack should be pretty evident. Very common. Hopefully did not overheat too long.

 

thanx for the reply.... i looked at the edge when the car was running, but it looked ok.... anyways, i think it is the switch as my cooling fan keeps running after i shut off the car...

so, my question is: does anyone know where EXACTLY the switch is? the guy at Autozone said it was in the thermostat housing..... i am in the process of taking the thermostat off, but i can't seem to get the small hose( located at the back of the thermostat, away from you) off... is tht where the switch is?? and how do i get the hose off? i already tried WD40

 

Yes- follow the bottom hose to the housing. The fan switch threads into the side of it. I don't remember any other small hoses that attach to the thermostat housing. the fans will run until the car gets cool-even after the ignition is off. How long are they staying on for??

 

till it drains out the battery.... then i'll have to jump start ith:

 

here's an update... i changed the following parts and the fan still runs! i'm guessing it's the fan relay now....

1. thermostat
2. ECT sensor
3. fan switch (on thermostat housing)
4. ECT gauge sending unit

anyone know where the fan relay is? is it the lil blacl box behind the passanger side headlight?? currently, i unplugged the cooling fan... will it hurt the car if i drive without the cooling fan?

also, there's a leak in the radiator, but ONLY when the car is running... should i patch it, or get a new radiator? thanx!

 

of course the best solution would be to get a new rad but depending on the size it could b patched

 

how much for a new rad? also, i think the crack is pretty small cos it only leaks when running... no leaks if the engine is cold

 

Look on Ebay. For a high performance radiator u will ay about 300 but if u get the run of the mill stocker about 90-150. If u fix the leak it could easily come back or hinder its performance

 

lol.. it's my beater car.... as long as it runs, i'm cool with it no performance mods watsoever... all stock! i'll try looking at autozone or the junkyard..... how difficult is it to replace the radiator? and if i bring it to a shop, how much would they charge?
