leaking hose '91 Ford Probe

infj23 on Sun July 05, 2009 11:09 PM User is offline

Year: 1991
Make: Ford
Model: Probe
Engine Size: 4 cyl
Refrigerant Type: 134a conversion

All the 134a leaked out, so knew I had a leak. Drew down a vacuum as well as possible and charge the system with nitrogen. Heard a lot of hissing and tracked the sound to an obvious leak. The problem is in the hose between the high side fitting and the condenser. Moving from the high side fitting, this hose goes down. About halfway down there is a hose connection where two metal pieces meet. Both pieces feel smooth and round (not hex). The leak is where these pieces meet.

I have limited shade-tree experience with auto A/C and have never experienced a fitting like this. I assume there is an o-ring in there. How are these pieces separated? Special tool required? Any tricks to get to it (it seems like a tight fit). Or do I need to replace the entire hose assembly?

Before this leak developed, the system cooled nicely.

Thanks in advance!
Doc

Ford. 1991. Probably a "spring-lock" connector. Not one of Ford's better ideas. There are special tools for this, then you must pull, twist, and tug. Good luck, you'll need it.

Is this the tool that is a round piece of nylon with a hole in the middle and split on one side so it can slide around a tube? Then push it up against a spring to separate the pieces? is that the one you mean?

Yes, be sure to change the O rings before snapping it back together and inspect the connection for cracks.. Here is a link to

springlock release tools

The line you are taking about may have an O tube in it, if it does, pull it out and inspect it/change it..

Thanks for the feedback. Just to be sure about this fitting, here is a picture of it. The fitting in question is inside the black box. So is the springlock tool previously mentioned still the right one?



Thanks again!

All I can see inside that box is a rubber hose that "looks" like crimp, which of course does not come apart, I would need a better pic of the fitting, or I'm sure there are others on the system that aren't obscured by anything else that you can take a pic of.. ..
