I have had an on-going heat issue with my rig. The Jeep water temps run in the 220-225 range on hot days with spikes up to 233 having been seen. Even with 2 coolers, the tranny will also get hot towing my AT Horizon trailer so I have no choice but to deal with it. This time I am not screwing around :coffeedrink:
The first mod (first picture) will be the addition of a fan driven Setrab 19row engine oil cooler. This will take the place of the oil cooler I am currently using which is inside my Novak radiator. Using an infrared temp gun, it was clear that my water temps were actually heating up my oil so that has to go.
I'm looking to run hardline along the top of the passenger side framerail to the rear corner and mount the cooler up inside the rear corner above the bumper. I also have 1/8" steel corner guards so in addition to being dead space and perfect for a small fan driven cooler, the area is reinforced. I'll be using braided Aeroquip hose and a/n 6 to flare fittings at the hardlines front and rear and a/n 6 to m22 fittings at the Setrab cooler. I am not worried about the length of the run as the Jeep 6 cylinder was used in many different farm implement applications where remote oil coolers were mounted on runs 4-6' in length using the stock oil pump. I will be installing a check valve to prevent drainback as a precaution. If we can pull this off, it will be pretty trick. Pix to come on that.
For the transmission, I am currently running a Currie billet style tube cooler mounted to the drivers side frame along with a fan driven B&M cooler mounted under the tub opposite form where the stock muffler sits. That set-up has proven to work just fine in normal conditions but with the addition of my AT trailer, the tranny will get hot when pulling long grades. To remedy that, I ordered another Setrab cooler...this time a 40 row fan driven cooler with its own shroud (2nd and 3rd pictures). This one is going to be interesting ...mock up with cardboard told me it would fit but once it showed up at the house last night, I started to have second thoughts. If I can get it to fit, the frame rail cooler will go. If it won't fit.....Setrab offers a smaller 30 row that might fit and I have also thought to plumb 2 of the small Setrabs inline. My only concern with that will be the potential for pressure drop. Pix to come for this install as well.
All fans will have a manual shut-off for water crossings and they will be equiped with 165* on/180* off temperature switches.
The first order of business though will be pulling the entire exhaust (I have it built so it disassembles into 3 sections) and taking it to get ceramic coated. I'll be haeded to this shop on Friday to drop it off. $22/linear foot will get me a nice coating of silvermetalic thermal ceramic heat barrier.

......BTW......the Jeep is still for sale. $25,000 firm and it will include this current round of mods which is why the price is now firm.
