I just picked up a ZJ trans cooler from the junkyard today ($15!). There's tons of posts regarding installation of other coolers, but I couldn't find anyone that installed a ZJ cooler. Has anyone here installed one on their XJ? If so, how did you go about it. I am familiar with which line to use.

Looks like I need some 3/8 line, barb adaptors and hose clamps. Am I missing anything?

 

I would retain the stock cooler in the radiator and run your aux cooler inline after it. 0.02.

 

For sure going to do that. That's the general consensus from what I've been reading. I'm looking at getting those zip tie mounts. Otherwise I'm going to have to drill

 

Alright, I completed the install this weekend. I had to saw off the hook style bracket so I could fit it vertically. I ended up going with the zip tie mounts because I couldn't easily mount it anywhere else.

I ran it in line with the rad cooler (after). Overall, it was about $45 including the purchase of the cooler. Not much of a savings from a brand new cooler, but it was worth a shot. Also, on my 2000, the top trans line going into the radiator is my return line. I confirmed it by following it to the rear of the transmission. This is the return line according the service manual.
