What happens if an oil cooler fails?

When an oil cooler fails, it can force all the coolant out of the engine and raise the risk of an overheated engine, which may lead to possible engine damage. If the leak is significant, you’ll notice coolant on the ground or see steam gushing out from underneath the hood.

Do you need to remove the oil cooler adapter?

You need to remove the oil cooler adapter and replace it with a standard non-cooler adapter then reinstall your filter on it.

Is there a way to bypass the oil cooler?

The old engine was full of nasty slug, so for sure I will at least replace or bypass the cooler, no way I’m letting that nasty junk back in my new engine. I would bypass it. All you need is GM part# 3952301 (adaptor) and (2)GM part# 3951644 bolts. That will take the place of the exsisting oil filter adaptor for the cooler lines.

Can you just tap the oil cooler and plug?

Catastrophic engine failure is what I would fear. My lines were modified to accept AN lines,and provided the solution that I prefer. not plugging the lines..plugging the adapter.. and totally removing the lines to the front of the car.

Can a car run with out an oil cooler?

For average day to day use, it isn’t going to make a difference. There have been more motors with out the oil cooler in the past then there has. They are known to start leaks on the hoses and so you are introducing a more complicated structure for little gain.
