There is tons of info on this forum about it.
IMO this is 1 of the best MODs for the money you can do.
Here's the link to the search for "Tru-Cool"

Yep, Tha'ts what I used and used the write up on here for the install.
I just completed my second 3200 mile road trip with it from AZ to Illinois
works great at 116 degree outside temps running 80 up some big ass Hills through northern AZ

No Photos sorry,

I installed the cooler like this.

I removed the factory cooler the front of radiator. Drilled out the rivets from the bracket so I could put them back on later.
On the passenger side of the radiator is where the stock lines are for the internal cooler, remove lines and install fittings and place a hose between them to bypass creating a U shape.
You will have to cut the bottom line going back into the transmission, put a piece of hose on it and run it to the cooler.
The output line cut the line and run the hose to the other side of the cooler.

Any cut lines I used a pipe cutter then double flanged them to make a mushroom.

The only problem I have run into is the positioning of this huge cooler. Right now its hard to close the hood because it is hitting the 2 bolts for the bottom brackets. I will have to reposition this later.

So how does it work, maybe to good. I drove to work today (55F) and the temp never broke 130F, and most of the time on the highway (80MPH) it stayed around 110F. I am not sure if this is ideal or not, as I just went by the recommedations here. So if anybody knows about this please let me know?????

While doing this I changed the filter and fluid. After I changed the filter, I took the upper radiator transmission line off and put about 5" of rubber hose on it. Then clamped it to a big bucket. I had my wife start the H2 up, and as it pumped the fluid out I poured new fluid in until it ran out cherry red.

So while I was at it I decided to change all of the fluids- radiator, diffs & trans case.

Anyone try a fan on the factory cooler??? I have been told that a larger cooler will affect the AC.

Just an update to my recent install.

I just came back from vacation in northern Italy. The temps were around 90 with very steep inclines. The temp got up to about 170 at the very highest, but normally hung around 150. It was slightly cooler in the Swiss Alp but the mountains were quite steep, the temp never broke 170 there either.

So the temps do start to rise it just takes a little while before they get there.

Seems now for the most part they hang around 150 after driving for 30 minutes or so, otherwise around 130.
