Drain plug on oil cooler..?
 

Has anyone ever tried this? I mean can it be added in?

SO U should have one filler plug and one drain plug

:confused:

ditto

bwahahahahahaha are you serious?

What a useless post. :gtfo2: To be honest, I don't think there needs to be a drain plug because you have one in the oil pan.

I think OP was meaning so you could drain the cooler when you change the oil (without removing it).

I was actually thinking this but there is a major problem... the cooler has rows, it isn't like a pan where all the oil gravitates to the bottom of hte unit. The only way to have a drain on an oil cooler would be to have some sort of removable seal on the bottom row which would be a big liability for a company to design and nearly impossible for a basic user to fabricate.

The possibility of leaking would be way too great and then you have a much bigger problem.

Agree

If you drain the cooler. You would need a way to refill it. As you would end up with an air pocket in it. When you would first start your engine after an oil change. The engine would run without oil pressure for about 30 seconds or more until the cooler could fill back up. ;)

When I first installed my kit I didn't put any oil in the cooler, only in the pan... I think it should be ok because when it is below 180 it is bypassing a good amount of oil (if you have a thermo plate) so there should be some pressure recirculating. I get what you are saying though.

not true, air is vented off through the intake. your oil pump is a positive displacement driven pump off the pulley. plus the split happens after the oil pump at the filter and adapter. the oil returns back into the pan after it is cooled.
