A Bad Day

Gerald K4NHN on Thu November 22, 2007 11:01 PM User is offlineView users profile

Year: 1996
Make: Jeep
Model: GC
Engine Size: 4.0
Refrigerant Type: R-134

I decide to to locate the leak in my Jeep a couple of days ago. It had gotten to where when I pulled a vacuum on it, it was gone in about 5 mins... I pulled the two lines to the evaporator apart and found some rubber caps that fit pretty good on the lines. A couple of clamps to make sure that they sealed.

I pulled a good vacuum on every thing else under the hood and it held for over four hours and the gauge never moved... EVAPORATOR

I'm not looking forward to replacing it and the heater core. From what I've read, it a real PITA.. It seems that I read somewhere that the date that the vehicle was made, there were two different evaporators for that year model.. And they had to go to an OEM to get one that really fit the housing. I noticed on the AMA parts, they list two different ones and I don't know which one is correct. Other than one is alum and one is copper... I can only guess that the original one was alum...

I think that I ran across a posting some where that had pictures of a 96 while they were doing the job.... Also where someone had actually cut into the housing and then just slid the coil out and then sealed the hole back up. Not sure if that was a 96 or not...

I never can find stuff like that when I try and search for it when I need it...

Hope everyone had a good Thanksgiving.

Plate & Fin would be my personal choice.

On the '96 GC it is no picnic. The entire dash comes out, from door to door - before you can remove the suitcase the evaporator & heater core are in. Things like the PCM need to be removed, and the coolant drained before disconnecting the heater core. The fasteners that hold the suitcase on the firewall are removed from the engine compartment.

Take your time, and pictures if you can for reference. You will need to pry up several plastic trim panels to get the dash out - I recomend doing this job in a warm place to avoid shattered plastic. If that is not possible, put a space heater in the vehicle a few hours before starting to pry on the dash.

I do not believe there is a reasonable way to cut out an evaporator on that vehicle.

Thats some good information about heating the inside. I hadn't thought about that.. I would have broken all the little tabs that hold everthing in place..

You kind of get the idea they were made to be quickly snapped together with no thought of having to take them apart for required repairs. Spent 20 minutes last night trying to get off the air cleaner in my Cavalier without breaking any plastic tabs, that was the bad news, good news, only took me about two seconds to put it back on.
