Did 4th gens come with a factory oil cooler? My 95' has a oil cooler mounted below the radiator behind the lower cowl scoop. Was this a factory option or aftermarket?

 

It is a factory option.

 

That does not sound like the factory cooler. The factory cooler uses coolant from the radiator to exchange heat with the oil at a special adapter on the oil filter mount.

If you have a small radiator coil looking thing for your oil cooler, it is not the optional factory oil cooler. The coil type is better the factory cooler, anyway.

 

The 95 has an option of a factory engine oil cooler.

But it is not an oil to air cooler like you seem to be describing.

The oil cooler is an water to oil type, no external fins or anything like that showing.

It looks like an aluminum spool that mounts above the oil fiter. Two aluminum hard lines run into the side of it. These hard lines are attached to hoses that run to the block and the drivers side of the radiator. No oil lines or exposed fins.

My car is a factory 95 M6, that I ordered new, so I have one. I think the KC4 was the option code.

Breakmyfootoff is right but I am not sure that the OEM design is what you have.

What you have sounds to me like an add on power steering cooler or engine oil cooler. Trace the lines, if nothing goes to the radiator tank, then it is not stock.

Some people say the stock setup plugs up, so even if it came with one, it might have been replaced with aftermarket.

It looks like a mini radiator, prob 2-3" wide, 18" long, Ill trace the lines later today

 

Could be a transmission cooler. That seems more likely to me.

 

Sorry, my bad. I've never seen one. I just knew that the factory oil coolers were mentioned in the instuctions that came with my supercharger.

 

He's running a M6, so it's not an aftermarket tranny cooler.
