All factory installed engine oil & tranny atf coolers come and go from the radiator.Hmm……my 08 Yukon looks to have an external oil cooler and external power steering cooler from the factory. Nothing is incorporated into the radiator, is this the tow package?
like @Geotrash said, if there are lines in/out of the passenger side of the radiator? those are for the ATF/tranny, and lines in/out of the driver side of the radiator? those are for engine oil.
What is the rpo code (glove box)?
My 07 Yukon has a ps cooler and a atf cooler in front of the rad and the rpo code is KNP and is okay for light duty towing. No engine oil cooler or lines connecting above the oil filter and to the driver side of the rad.
