I'm overheating ONLY when drifting...
Radiator cap - new
Radiator - standard repaired (had a damaged bottom tank seal)
Thermostat - now removed (before it was removed it overheated alot faster)
Where I practice is pretty much 2nd gear (not limiter bashing)
I don't know whether it's the fact that there's no traffic after a 'lap' to wait in to give it a chance to cool sightly. Needle starts to rise after 5 minutes of constant drifting.
Idling: fine
Driving normal: fine
Spirited driving: fine
Drifting: temp problems
The fans do work. They will be wired in manually soon.
I'm very certain the coolant is bled properly, I know they are a bitch in these cars. But I get hot air when I should etc, etc.
It gets to the point sometimes where it fills the expansion tank and overflows!
I'm pretty much out of ideas other than getting a thicker radiator and better fans. (Ideally dont want to mess about with a radiator as Im doing a 1JZ conversion soon)
Last time I was at the track I had similar problems, but it was drinking the coolant then temps raised (I believe that was due to it pissing out the leaky radiator). It never overflowed and there are no symptoms of headgasket failure. I haven't tried a sniffer test.
Any ideas? Should I bleed it more, even though it seems like it is bled? Im half tempted to bleed it everyday until the 31st (next drift day on a track)
Another thing to note is that the coolant is probably more 90% water now, I refuse to put it to what it should be until it stops wasting it.
