95 ZJ Trans cooler quick connect

contraption22 · Mar 12, 2013

Hi Guys.

This weekend I figured I would start a quick project fixing a leaky trans cooler line on my '95 4.0. While I was at it, I added an auxiliary cooler. I found the leak from one of the swedges on the feed side of the cooler line, right near the lower nipple on the radiator. I have been unable to remove the quick connector on the line. I was able to disconnect the feed side with some needle nose pliers, but I am just not able to reach in there on the other side because the lower radiator hose is in the way.

The quick connecter has two plastic tabls that I was able to squeeze together to release the return side.

So I went to the store and bought this.

I am just not getting it right. I really want to take this quick connector off and flare it so the trans cooler line doesn't slide off and leave me stranded some day.

Any help would be greatly appreciated.

Thanks,

Mike

I bypassed the radiator cooler and ran the lines straight to the external cooler in front of the radiator, many have done this and it cools much better.

Thanks. I would consider that if it were a summer only vehicle, but I would be just as concerned with the trans fluid taking too long to warm up as it would it getting too warm. I'd had issues with that in the past on other Mopars. Those, thankfully, had good old hose clamps on their connections.

I got it off. Had to contort my arm and hand in a way that really did not seem natural, but i got it off.

Just to update all on my progress in case it someday helps somebody else.

I was able to remove the quick connector from the radiator, cut off the swedge to the rubber line, flare the quick connector and replace it. With that all done, the leak seemed to get worse. I disassembled it again and found that one of the orings had been compromised. search for OE and aftermarket parts was somewhat fruitless, so I attempted to replace the Orings in the quick connector myself.

Searched through some A/C O-ring assortments I had and found some rings with similar dimensions, if not just a hair fatter than the originals. Using a pic, i pulled them out of the connector, along with the whitish plastic spacer that separated them (nylon i think), then carefully pushed the new orings and spacer back into the connector one at a time. I lubed them up good with some petroleum jelly, and re-assembled everything. Initial testing seems to show that it is leak free at this point. Time will tell. I will report back after cleaning the engine compartment a little better and putting some miles on it.

If all goes well, I will post this into an appropriate tech section with part numbers.
