Engine Oil Cooler Retrofit

[2007YukonXL]

My 2007 GMC Yukon does not have an engine oil cooler and the radiator does not have the oil cooler fittings (it only has transmission oil cooler fittings).

Has anyone installed an engine oil cooler in a non-engine oil cooler car? The easiest way to do this would be to buy a new radiator with the engine oil cooler fittings and the factory engine oil cooler lines (and I might do that) or if there is a kit available with the oil cooler and lines pre-made I might go that route.

Any suggestions, advice, pictures, or well wishing would be appreciated!!!

THANKS

I’ll suggest to use the OEM parts. Or at least use braided stainless if you go aftermarket.

I had an unfortunate experience with an aftermarket remote oil filter once. Hose let go and drained all my engine oil out on the road.

oem parts will do it, you just need the radiator, the 2 oil lines and the adapter that goes above the oil filter, if you look at the area above the oil filter there will be a block-off plate there in place of the oil cooler line adapter. should be a wide diamond shaped plate with 2 bolts.

I'll be doing this at my next oil change. I replaced my radiator a few months ago and I got one that had the built-in oil cooler. I bought an OEM oil cooler hose assembly (GM Genuine AC Delco #20828695) to have on standby and just left the plugs in the oil cooler on the rad for now. The rad I got is Denso #221-9514. It has a 5/16" thicker core than the original and trans oil and engine oil coolers. Got both from Rock Auto.

If you don't want to replace your rad, you could get an aftermarket external cooler and mount it in front of the radiator. Get the AC Delco hose assembly and use hose and hose clamps to connect the aftermarket cooler to those lines. I'd double or triple up on the hose clamps.

Last March I added a Hayden #696 oil cooler. I built my own lines.

Here's a TYE thread I started about it. See post # 1, 43, 75, and 100 for pictures.

My truck didn't come with the EOC from the factory either.

I ended up adding an aftermarket stacked plate style cooler and a dual remote mount oil filter housing with oversized filters. I had custom hydraulic lines made to plumb everything together.

Filters are mounted to the inside of the passenger frame rail behind the front bumper and infront of the crossmember.

Cooler is mounted in front of A/C condenser.

Wow that's an awesome setup! @kbuskill

I have changed it since then and added the factory oil cooler, that is mounted in the radiator, into the system along with everything else.

I also ended up redoing the lines as the hydraulic lines started leaking after several years.

Like others, I've done what you're proposing. I did it in conjunction with an axle ratio change, so I had the front diff out at the time. I also did drivers side motor mount at that time so that gave me some further room.

Running the lines would have been challenging with everything still in place. But I believe others have done so. I used the Denso radiator with oil cooler function that many on here have used/recommended. For some reason, I used the Dorman line set instead of Delco OEM, but I haven't had any issues with the Dorman stuff.
