    from a redlight, i got on it a little bit and 15 sec. later i start to smell coolant inside the car. roll my windows down thinking its coming from outside. then i notice a bunch of white smoke trailing the car. i pull over, open the hood and i find coolant sprayed all over the engine. it came from the upper intake area as the hood insulation has a huge wet spot right above it.

    I looked for anything out of the ordinary and couldnt find anything that could have caused this!

    anyways i start to head home (3 minute drive) and then the car starts to overheat and it threw a code...

    code is P1285 manufacturer control fuel air metering.

    Car is sitting in the driveway right now, where do i begin to diagnose the problem?:confused:

    Was the smoke trailing the car or coming out of your tailpipes?? Also, Did any of your hoses burst or are they intact and in place?? What it sounds like is that it could be a stuck thermostat, but let me know the answers to the other questions. :thumbup:

    i dont think the smoke was coming from the tailpipe, just drifted back from the engine compartment. i didnt see any hoses burst towards the front of the engine, is there any hoses towards the back? heater hoses maybe? i do all engine work myself but never have i dealt with the cooling system..

    Ok, I'm leaning toward your thermostat then!! If the thermostat was stuck closed, then that woud explain the back pressure and splattering of the coolant. To find out, you can take the thermostat out and put it in some boiling water to see if it opens!!

    thanks, will test out the thermostat... But wouldnt the place the coolant burst from need replacing? ie a burst hose?

    I don't see a burst hose.. I'm just saying, where would the coolant have came from in the first place? I'd assume a hose would have burst open.

    If you don't have a burst hose, and it is indeed a stuck thermostat, then the coolant would be forced out from the sides of the radiator cap itself.

    Took off thermostat and placed it in boiling water - nothing happened.

    I guess the thermostat is my problem :thumbup: Im glad they are only 5$ to replace. Will replace tomorrow along with coolant flush and report back with results.

    thanks reaper!

    I hope those heads didn't get warped if the car overheated. That $5.00 part will turn out to be an expensive job.

    the temp needle didnt go past the "red" on the guage but if i were to keep it running for 30 sec more, i think it would have... I hope that didnt happen..

    Looks like that upper radiator hose is swollen like crazy. These radiator hoses are hard as hell to find where it tore up. You really have to look for it and once you find it, it'll be an itty bitty hole. I believe thats where it popped due to the thermostat not letting any of the coolant in.

    I took off the hose and did a thorough inspection and found nothing. If you look at the video, you can see where the coolant hit the hood insulation. It's directly above the upper intake..

    Replace thermostat

    Fill system with water

    Connect coolant pressure test kit, available for loan from most auto parts stores

    Find leak

    Replace defective part(s)

    Fill with mixed coolant

    Know it was done right and the problem is completely fixed

    No offense, but wouldnt you want to use pure coolant? Yes it is thicker and more expensive, but less likely to boil and potentially burn someone? Or is it the other way around, im jw.

    Using "pure coolant" will not make your temperatures decrease any from the suggested 50/50 mixture. In fact, it will have worse thermodynamic properties than that of a 50/50 coolant-water mixture.

    Isn't it made concentrated? Unless you buy the pre-diluted stuff?
