Dual Combo Tranny/Engine Oil Cooler Install

[GMC K1500 SC]

Here are the pics of my combo engine oil/tranny oil cooler...tranny cooler is a 4 pass and the oil cooler is a 2 pass with a 1250cfm fan in the front of it which acts as a rock protector too.....you can't see it unless you look under the bumper spoiler...I will be doing some testing on the temps with my scanner...for now I did leave the factory tranny cooler in the front of the engine as the oil goes through it last back to the trans...I want to be able to hook up the cooler fan to my front radiator fans so when they cycle the first time the tranny/oil fan will always stay on? Now sure how to wire this to a relay? (cycle and hold) But I will figure it out.

There are now no lines going to the stock radiator...next step is to install the intercooler and 2" shorter alum radiator with just one engine fan.

I love this setup....I added another relay so it comes on with the reg. fans...will have a manual override switch installed soon!

Installed override switch. It also comes on when the fan come on manually....also hooked up a wire to a one way diode on the AC low pressure switch to the fan temp relay so the fan will come on when the AC is turned on....have to have a diode as if you turn on the override switch the AC would come on even though it was off at the dash ac control :)

Update: System working great even in hot 100+ weather...also allows the radiator to work easier as it does not have to cool the tranny or engine oil.
