Yup... I fucked up.


Fan relay is fucked and i have a stock rad (wtf i know?).. getting Koyo this week.

Let the car idle for a few minutes and took it for a 5 minute drive. Coming up to my driveway.. the car stalls. I couldnt get it started. What do i see? Grey smoke coming out of my hood and the smell.. omg the smell -___-. So I look at my PFC and it says 186 C

Got it up my driveway, turned it off... looked at the bottom.... ******* coolant hose leak. Added some distilled water the the WP and overflow tank and after a few minutes it went down to 116C then to 85C.

Ran it up again and it idled fine and everything. I know i fucked somthing up... just gotta find out what.... and now the wait for alum AST and koyo.


The main problem here (besides the coolant hose leak)..... fans werent ******* on because of the fan relay is fucked.

Hopefully all is well. Soon.

186c? damn, that must be a record.

omg 186C!! RX7 RAGE is right, thats a record in my book.

after you get those parts im not sure if your engine isnt permanently damaged.

Heres a simple equation: Temp > 120C = FUCKED.

Sorry to hear that though. You'd be damn lucky if nothing is damaged.

What could I have damaged though?

Warped housings are a good possibility.

What test can I do to check things? For example the coolant seals and etc..

Compression test? or?

RX7 RAGE

iTrader: (22)

white smoke will be the test

i let it idle for a minute after it went down to normal temps..... no smoke.

although it was grey/white smoke right before i turned to car off... when it was 186F.... but im not sure if that was from the enginebay or exahust.

Damn.... I am curious to see how it runs after an overheat like this! Good luck!

So the car idled for a few minutes, then went on a 5 minute drive and already 377F???

That seems VERY unlikely. Either for some reason the PFC has a wrong reading or you didnt have any coolant in the engine at all causing the temp to rise soo quickly which even then is unlikely cause a few minutes of regular driving shouldnt raise the temp that high, unless you were revving the engine at 9 grand the entire time.

But if that temp is true for some reason, consider your engine pretty much toast.

So you started your car and drove it knowing your fan relay didn't work?

Those temp numbers are suspect, given that the motor actually still runs... that said, for god's sake fix your car... or since you have a PFC, MONITOR YOUR TEMPS. How the heck did it get past 120C without you A. Noticing. B. Taking preventative action, like shutting it off?

This is why I recommend Peak/Warning/Hold gauges.


turBRO240, do a pressure test on your cooling system. If that holds, you don't have a ton of smoke pouring out the exhaust, and you aren't loosing coolant; you should be ok.

I would think your coolant seals would be done for. I really hope not though.

Very good advice!! I have defi's, and anytime mine go over 200f the little light goes on so I def notice.

I just baught a Koyo and new hoses (there was a small coolant leak). I dont think the pressure test would be accurate because of the curren leak.

While driving I DIDNT boost at all. The most probably cause was there was NO coolant/water getting to the engine hence the quick rise in temperature.

I will invest in some peak warning gauges soon. I just hope my water seals arent destroyed.

How would the PFC be wrong? Im finding that hard to believe but it is a small possiblilty. I mean it had to have been way up there (250F+) i heard the water BOILING. And on the passenger side oil cooler duct some green coolant was leaking... but very little.

I topped off the WP filler neck and coolant overflow tank with distilled water. 3 minutes after shutdown it went to normal temps (85C). But going up my driveway the car stalled and wouldnt hold idle for a minute and i smelled and saw greyish/white smoke but just a little bit.

that is pretty hot BUT it wouldn't suprise me if everything is ok. It's really a crap shoot when a vehicle overheats. Things you'll want to look for is exhaust smoke and/or champagne bubbles in the coolant. If you're ok after checking these two things you might've gotten lucky.

About the only other test you can have done is a hyrdocarbon test.

It would suck major ***** is anything is royally fucked. Im just hoping for the best, but thinking of the worst . Ive already put enough into this... but this was my stupid mistake. Ill firing it up when I get home and see how it does.

Anything specific to look for when i start it up? besides white smoke from exhaust? If the water temps stay normal you think everything should be ok? It wasnt a hot day when it happened maybe 70F outside and air temps on PFC were at 28C.

Grimple1... you live 20 minutes away from me... awsome. I dont know any other single turbo FDs around here.

Fix cooling system, and keep driving until/if it stops starting due to coolant drinkage.

turBRO240

iTrader: (1)

Will do.

Sprockett

WELL?

NewbernD

iTrader: (1)

If you had a coolant leak as well, is it possible that the temperature measured was the steam temperature and not the water temp?

turBRO240

iTrader: (1)

Well... the car runs fine and idles fine... idle temp is 85C but when i rev past 3k white smoke comes out of the exhaust... not boat loads but you can see it around the car.

Sprockett

White smoke = coolant...usually means rebuild time. Without asphyxiating yourself, smell the exhaust to see if it has a sweet smell. If so, it's definitely coolant. If not, it might just be moisture.
