Oil cooler

Has anyone added an oil cooler to their C4? I did read that some C4's came stock equiped, my 86 did not and I'm thinking of adding one to help cool the engine.

RE: Oil cooler

My 89 came with the oil cooler.Think it was part of the Z51 package.

RE: Oil cooler

My '90 has an oil cooler. My friend thought that meant Z51 too. Looked at the codes and I have the regular suspension.. Go figure.

RE: Oil cooler

Thanks.
I can't think of any good reason not to do it and it's got to shave a few degree's off the oil temp.

Once GM started using Mobile 1 in the 92-96 models the oil cooler was no longer an option.

RE: Oil cooler

I understand the 86 ran hot becuase of the emmissions and with the introduction of synthetic oils and continued technology, they probably didn't neet it anymore.

RE: Oil cooler

If my '90 doesn't come stock with an oil cooler, and I am using synthetic oil, the addition
of an oil cooler can only help right? If so, would it help enough to justify cost?
