[92VR4Red]

my car is overheating bad... makeing it disabled... i replaced the themastat... its full of coolant... not leaking any coolant... and both fans work... WHAT COULD BE THE PROB? it also white smokes when i first start it up but doesnt when i drive...

how long after you start the car and the overheating, min. or longer, is the radiator hot also or just the temp gauge reading hot. Did you r&r the thermostat or a shop. I don't think the smoke is anything to worry about but the more info the better. If your head gasket is blown you'll get coolant in your oil which creates bubbles.

i replace the thermastat my self its in right. it over heats pretty fast now.. at first it tooklike 30 min now its like alomst intstantly now. the radiator is ofcourse hot. the temp guages reads at thew red line. ive head these 3 sujestions over and over 1. water pump 2. head gaskets 3. crakced block.

holy $h!7 i just relized my typos sorry im not in the best mood.
line 3 ** I have heard**

I've replaced a thermostat with a brand new one only to have it fail. If it's the thermostat the raidator should stay cold and you should over heat very fast. Those bubbles will show up on your dipstick. Not to doubt your mech. abilty but is there any chance of the therm in backwards. There is chance the old therm was only opening partialy and the new not opening at all. The pain threshold for heat is 140 digrees when I said cold above I ment anything up to the pain threshold.

Is there a chance that stopleak has cloged the radiator?

[92VR4Red]

well i double checked on the thermastat before i put everything back together... what do you mean the stopleak has cloged radiator.

[92VR4Red]

?????

[John Pannebaker]

How much of the cars history do you know about. There some real crap out there sold to stop leaks in radiators it does work but in time it clogs up the whole radiator. This could have been put in by a previous owner?

i dont know anything about the radiator... but the guy i bought it from kept it in real good shape... when i bougth it, it was all stock. he had papers showing that he went and got the timing belts replace recently ($1000 bill) and other stuff... the car history was clean... the car is in great shape. and i have had it for like 5 months with no problems till now. i think its just the old age geting to it... its a 92 with 120,000 miles on it...

[92VR4Red]

and all i have done most likely did not cause it to this... i have put turbo back exhaust, air filter, and a turbo timer so far. infact i went to go get a new intercooler y pipe, hks blow off vaulve, and a boost control. when i was comeing home it started to over heat about 5 miles down the road to my house...

[John Pannebaker]

At 120k the timing belt should have been done twice With the belt they always change the water pump so its not the water pump. Give a quick look on the dipstick for bubbles and I'll do some more thinking.

[92VR4Red]

will it have bubbles when car is cooled??? because it hasnt been driven in like a day... so should i take it down the drive and back and check????..

[John Pannebaker]

let the car idle till it over heats (not till it stops it self), then check radiator for intense heat and oil for bubbles get back to me at [email protected]

ok this is weird but get this ok... i was driveing my car to make it heat up ok... and as i was driveing it was geting close to red line so i decide to turn around. just as i turn around and head back the temp drops back to normal infact a few notches cooler... explain that :S
