99 Jeep Cherokee Sport

I'm replacing the radiator and having trouble with the "quick" connector on the transmission oil cooling line. I cut the brass that comes out of the radiator, and there is several inches of it now sticking out of the end of the trans oil hose. I bought these tools to separate the connection. Is either one of them the correct tool for this job? Is the idea that the tool would go around the brass tube, slide down into the end of the trans oil line, and then I push really hard to try to dislodge the spring clip?

Also, is there supposed to be an "O" ring somewhere in this connection? If not, what keeps the oil from leaking out?

 

Either one f those should work. I'd try the metal one first since the extensions are a little longer. Sometimes the connector gets some crud in it and can be hard to disconnect. You shouldn't have to press really hard. When you push the disconnect tool in, it will expand a spring and then it will come out over the ridge on the inside line. Sometimes I push the female end into the tool and then pull it back to remove. A lot of people cut that line and then use rubber line with double hose clamps. I have a 98 where the PO did that and I could never get it to not leak so I replaced it with a new line. Once you get the technique down for removing that connector, it's really easy to get it off when needed.

 

I have found that it is neccesary to flush out the built up scum by flushing repeatedly with degreaser, while work the tool, (or a cut permanent marker cap) back & forth

the grit prevents the parts moving enough to disconnect

 

I personally could not get this connector to open with a traditional tool. I had to use 2 pieces of 4mm wide steel offcut from one of our metal cutting tools and press them into the connector. I did see a video where they used the lid from a sharpie marker (which fit perfectly) but mine just snapped apart with the force I had to use.

The little tabs are what you need to press back.



The picture is from the gearbox end but the tabs are the same. They are right down in the connector

 

I tried both tools. What is it specifically that they are supposed to do?????? I pushed the tool all the way down in the female connector by hand and by squeezing with channel locks. I twist and pull. Nothing. I cleaned out the connector with carb cleaner. Made no difference. Is pushing with the tool supposed to force the brass tube further into the female connector? If so, it's not working. The brass tube does not move at all. The brass bit with the four tabs will spin around in a circle, but the tabs are still locked under the rim of the female connector. What the f**k am I missing?

Better yet, if someone in the Iowa City, Iowa area wants to come to my house today and disconnect this so I can finish installing my radiator I'll pay fifty bucks. All you have to do is disconnect this connector from hell without breaking it. Anyone?

And you'll have to drive me to an atm cause my fu***ng car won't run.

 

I hope this crude phone drawing helps give a view of what's going on.



So the cooler line clamps over the brass with 2 plastic tabs. The tool is supposed to push those 2 tabs outwards freeing the brass connection.

 

OK, I got it. I was confused about what was happening inside the female connector. Problem solved and radiator installation has begun. Thanks for the help!

 

The rest should be straight forward for you.
