Ran my PRO codes today and looked around the engine bay. I have PRO codes KC4 for external engine oil cooler and KNP for external trans cooler. Z85 suspension and Z82 trailer pkg. Made my freaking day having the KC4 & KNP. I did see the engine oil cooler lines coming off the engine. I also pulled some good diagrams from some online dealers. The engine oil cooler goes into the passenger side of the radiator. There is no external engine oil cooler. Engine oil cooler is the passenger side tank of the radiator. I had no idea there was a separate chamber in the top of the condenser for the trans lines. From the research I've been doing I'm only missing (terms of cooling) is the larger max tow pkg radiator, which should be a direct swap out. So I'm looking at swapping out the radiator and rear leafs and adding tow mirrors. And throw a P3 brake controller in the dash pocket. I can live with those mods. As for shocks I'll stick to the OEM Z85's until they wear out and will do some bilstein replacements. I'm not a Rancho fan. Nor do I want some botique high dollar set of shocks. Believe it or not, when I built my straight axle 4runner rock crawler which was also my daily driver in Tampa, I tried a ton of shocks and ended up with Yellow Monroes. On my F250 6.0 which had the FX4 off-road pkg, which had rock hard Rancho shocks, I ended up with Monro Reflex shocks. The Reflexes transformed that Super Duty. Monroe does not list reflexes for our trucks...

 

Anyway, found some good parts diagrams. The engine oil cooler is on the passenger side of the radiator and has the larger metal piping. The below pic for the engine oil cooler looks like it's mirriored or something. Note the lines come off the oil filter side which is on the driver side. in the pic below they show the filter on the passenger side. Trans cooler is on the driver side of the radiator and then connects to the top portion of the condenser, using smaller metal piping. There is only the radiator and condenser/trans cooler. the engine oil cooler does not have a separate sandwiched cooler.

What's the rpo code for the larger rad, also do you have the part#? Did you do the swap? Thanks man

NHT is the code for the larger radiator.  It's the max trailer package.  I did find the part #, you can find it easily enough online with a GM parts lookup and it will give you two part #.  No, I never did the swap for the NHT radiator.  Can't say I've had the need.  I've used the truck extensively in the 76k miles I've owned it and live in Florida.  Truck never has gotten hot.  I've pulled 30' trailers and all kinds of stuff.  Just no need.  I figure if I still own the truck when the radiator finally goes out, I'll swap in the NHT version then.
