Oil Cooler

[paradox616]

Hi Guys,

Just wondering if anyone out there might be able to shed some light.

My 88 7mGTE (later block, 7m crank) mk3 has its oil cooler hoses blocked off for some reason, ive just rebuilt the motor and want to cool the oil.

now ive been told you cant use a Automatic transmission cooler as a Engine oil cooler due to the size of the passages, i don't see how this is important as currently blocked off there is no oil flow anyway. Sure transmission fluid is thinner than engine oil But can anyone give me any other reasons why its not a good idea?

Anyway id like some opinions as i have a 30cm x 20xm "radiator" style transmission cooler and am considering using that.

If you use the stock bypass cooler circuit yes you can use an Auto trans cooler.

I dont see it being a problem. Its got to be better than nothing.

A tranny cooler IS an oil cooler

This is the best way to set up a cooling circuit:

I'm aware of this, I was referring to engine oil cooler rather than transmission oil cooler

And, I'm telling you there is little to no difference

But, but...he was told there is

OP: Even if it were true you'd be surprised how much hot oil can flow through small passages. After leaving the filter all the oil going to my engine goes through the equivalent of a 1/4" hole. Been that way for years...

that's fair enough it is the reason i was asking after all
