Here we go, I spent my Saturday at the garage of a friend.
I replaced the following parts , it took me 8 hours, but I was alone all the time.....
1. Replaced the original fan and clutch with the 12 blade nylon fan of Grand Cherokees and Hayden Heavy Duty.
The removal was easy, thanks to the instructions given by Papaidingo.

I managed to make the swap by lifting slightly the plastic shroud.
Hope you appreciate the fine piece of technology that keeps the hood up, an umbrella, yes, but a Jeep branded umbrella

I remove the front engine guard (chromed plastic) and unbolt the top part of the black engine guard.
2. The condensor/TOC was really in bad shape, the TOC was a pack of oil, and the condensor ' s blades we're flatten by fan. Plus the whole thing was stuck with dirt and dry mud.

3. As the turbo cooler was very dirty, I removed it as we'll to allow a good cleaning with a water hose.
Look a bit the dirt that is stopping totally the air to go through.


4. Finally replaced the condensor/TOC with a new one.

I decided to assemble the Condensor/TOC and the turbo cooler prior to mounting back in place. This made the mounting easier I feel.
5. I replace the trans fluid with some good ATF4+ , replaced the filters (cylinder and flat)
Here it is. The tests I made so far showed no sign of overheating.
So I guess my problem is solved.
