Hey how do i know if my suburban has the engine oil cooler?
Juan M August 5, 2017
Just look if there is a connection for the oil line on your radiator. The 2 big hoses are of course for the coolant the 2 smaller hard pipe/hose are for oil.
Loic N August 5, 2017
It should have 4 small lines running to it if it has oil cooler. 2 lines if its just transmission cooler
Joe P August 6, 2017
There will be 4 steel lines, plus the inlet and outlet for the coolant, 2 steel lines are for the transmission, and 2 more steel lines for the oil cooler
