Oil Cooler

[19Yukon97]

Hey guys.
Anybody have an oil cooler on the oil pan? have had a leak for awhile now. its not my intake mani gasket. already changed that when i bought the truck. its either my rear main seal or transmission pan or the oil cooler. my dad got under the truck and looked and he really thinks its the oil cooler. which is the adapter that the oil filter screws onto... so if anybody has ever changed that gasket or o ring let me know. i need to get this fixed. its getting worse.
thanks.

When looking at your oil filter mount you would see two lines coming from it going to the radiator into the left tank which is where your oil cooler would be and would see it leaking in your coolant. If the adapter is the problem then disconnect your lines, remove your filter and the 2 bolts holding the adapter on to the block. A felpro gasket set is about $10

The quick disconnect fittings for the cooler hoses on the adapter are prone to leaking too. Go ahead and replace them while you have it off
