Hey guys i am about to do a tranny cooler on my 91 xj. I have a question on my radiator in the 91 what line is the return and the feed line? Also i assume its best to run the cooler in line with the rad right? Or is it best to run it by itself, I live in NY so it get cold here.

The Topmost line is Feed and the lower is return.

I got a massive Oil cooler out of a 90 Ford F250 Bar and Fin. Im going to give it a try. I am completly doing away with my In radiator cooler......

i ran a big *** intercooler on mine. i think its a 6 row or something. its like 14" long and 8" tall and i still run it through my radiator. runs great, brought the tranny temp way down, shifts smooth as butter now.

did you install before stock cooler or after?
what were your before and after temps?

posjeepxj

y not just convert you ac condensor into one

tannerp89

before, right behind grill in front of rad. jus removed the stock intercooler and used the tabs to mount the new one. and dunno what the before n after temps are, just know it shifts alot better since i put it on.

tannerp89

n cause i already removed the ac condensor when my ac pulley siezed along with everything else that had to do with the AC

i will be installing a Autometer guage hopefully tomorrow and drive around for a few days so i can get a accurate Before and after reading......

tannerp89

how are you putting the gauge in? id like to do that. one for my tranny temp and one for oil temp.

Im using a 3/8 Compression T-fitting in the Feed line that runs next to the trans as close as possible. the sender is installed directly into that.......

tannerp89

oh ok. so i could basicaly jus use a t fitting anywhere on the Tranny line with the sensor on it and itd work. so what would be the best way to do that for oil temp? drill a hole in the pan and install the sensor there?

In my experience you want put the temp sensor on the return to the trans. to see what the temp going to the trans is. Also dont forget to check the fluid level and add as needed when adding the cooler so many people forget to do that.

tannerp89

well when i put my intercooler on i changed the tranny filter n gasket so had to fill it back up anyway.

fishtaconc

well so many people forget about the extra volume of the cooler/ hoses and add the recommended amount in the manual. what kind of intercooler did you add?

tannerp89

ya true, not everybody thinks ALL the time. lol. and i put a flex-a-lite on it.

fits perfect, even used the existing mounting tabs for the stock intercooler.
