Trans cooler and fan

Anyone here installed an additional transmission cooler and installed a second fan? I'm considering towing my Jeep Patriot 1,000 miles but want to give my WK the best setup for the trip.

You could put a line from the outlet of the stock Trans cooler to an external cooler and then the outlet of the external cooler to the existing return line to the Trans. Don't think another fan is necessary

Keep in mind you are going to be very close to your max tow weight with that behind your rig. The Patriot is listed at 3273# curb weight (empty) and 4500# GVW. If you are towing it on a trailer or tow dolly you will need to calculate that in as well to your overall numbers.

3.7L is rated to tow 3500# and I am a big fan of keeping anything I tow under max rating by say 20%. If you are towing 1000 miles in the summer heat... be careful. A trans cooler and a trans temp gauge will be important. Does yours have the tow package already?

I thought about those. My thought process was that its rated where its at because of the gearing and lack of trans cooler.

Here's a cooler made to fit up front of the 3.7, no fan - about $56

(this looks very similar to the factory cooler I have on my CRD)

Here's one with a fan, that you can install just about anywhere you can fit it - about $220

I"m certainly not an expert, but I'm thinking you could use the passive system and you'd be OK. You might want to consider putting the Patriot on a dolly to save weight

If you tow that on a tandem car carrier trailer you will be way over the tow limit for the 3.7 (those trailers weigh about 1200 lbs). If you use a dolly it will be close to being just at the limit or a but over.Make sure the dolly has surge brakes at least if not electric brakes.
Backing up is difficult with a dolly. I've towed with my WK and it tows well but the rear suspension is too soft.
