Hey fellas,

I've just bought a JZZ30 off a mate. However this morning on the way to work I had smoke bellowing out of the engine bay. After I pulled over and lifted the bonnet there was trans oil all around the front air dam, the overflow bottle was boiling and after it was slightly cooler I checked the radiator it was full of transmission oil. It isn't engine oil as the dipstick or oil cap showed no evidence of milky contamination.

The a/m transmission cooler is air to air so I can't explain how transmission oil contaminated the coolant unless it was a duel radiator.

So my question is, do these run a duel engine/trans radiator?
Or is the fan hydrostatic?

the factory auto trans fluid cooler is situated in the lower tank of the radiator, u will notice 2 small hoses going into the lower tank. Possibly the inner auto cooler has corroded and is now pushing auto fluid into the radiator

Thank you for the response Scott, so in that case i'm just up for a new radiator?
Again much appreciated :-)

I would think things would need a serious clean. ATF would have been pumped right through the cooling system, heater matrix etc.

Possibly coolant has also gone through the gearbox.

I hope I am wrong, but get it checked out thoroughly, flush everything at the very least.

Yes I know that Pete, I'll be reverse flushing the radiator & engine. Auto trans oil change, flush the a/m PWR auto cooler, will be doing a minor service on the car while I'm there as it has been neglected from the previous owner for quite a while.

Thank you everyone for your help, I really needed confirmation on the rad cooler to complete my diagnostics. :-)
