removing aftermarket mocal cooler to standard
 

hi guys, when i purchased my car (a 2004 sti) it already ahd an aftermarket mocal oil cooler on it, i presume previous owner may have done a few track days.

I plan on doing none and general commuting and weekend blasts, i am having the cooler removed and the standard modine put back in the place, this is the right thing to do is it not? i very rarely see temps with the cooler over 80 degrees so i presume in fact having oil cool most of the time will probably do longterm damage? reassure me going back to normal is the best thing!?

If it has an in-built 'stat, i'd leave it. If it aint broke and all that...

it is a bit leaky from the filter aswell which i presume might be the sandwich plate as i had 2 new filters on it, but literally the oil temp never goes above 80 degrees really and thats on 10-50 fully synthetic

i think the stat in the mocal sandwich plates are set to around 80 deg.

thing is i thought operating temperatures for oil can be upto 110-115 degrees, the car will be not going above 400bhp so an oil cooler is not really required for road use is it?

For road use its not really required.

I'm running on mine,which is road car and is good to have in my view.
But if you have on your fitted OE Modine(which on mine has been not fitted from factory),OE modine will do job nicely.

If you're worried I'd keep it but add the OE Modine back into the system - you can run both (I do) this will get your oil up to temp as quickly as std. but when the sandwich plate stat opens (80ish degrees) will allow flow to the air/oil cooler and therefore keep temps undercontrol. Given the cost of oil coolers I'd just get the modine replaced and keep the mocal cooler (as long as it's thermostatic).

I'd keep it and fix the leak.
