Grand Caravan rear txv

Bob on Thu April 08, 2010 11:46 AM User is offlineView users profile

Year: 2005
Make: Dodge
Model: Grand Caravan SXT
Engine Size: 3.8
Refrigerant Type: R134a
Country of Origin: United States

Have a 2005 Dodge Grand Caravan that had 0 pressure in the system this spring. Knew I had a major leak to have 0 PSI. Bought some R134a with dye, and charged the system with it and more 134a. Ran system about 30 minutes and after sundown went looking for traces of dye. Near rear right tire, I could hear a hissing sound. Upon further examination, by leak detection meter and UV dye, found the rear txv leaking. Searching the web, ran into TSB where they extended the rear evaporator to 7 yr/70000 miles. Called dealer today, but my vin # did not qualify for this repair. So my question is how hard is it to change yourself? Has anyone done this? Some web chatter about capping the rear off. Neighbor suggest not doing that due to liquid might get back to the compressor. Any thoughts on that? Dodge says there is a new improved design. Tim, do you sell the improved evaporator/TXV? Any infromation would be appreciated.

Thanks

it should not be that hard minus a lot of items needing to be removed from the side panel. I do not have an R & R procedure but I have a diagram of the case assembly. If you email a fax number I can send it over.

Tim,

Have you seen this in your shop? Anything else I need to replace this? I have Nylog left from a previous order. Does the evaporator come with O-rings? Oil? Will an all data or Mitchell subscription cover the R and R? I've found this site.

You should also order the metal gasket kit & o-ring for the block valve and hoses. Might want to add a few ounces of oil also as I sure the evap with retain some. Drier is another option if the system has been opened. I have Mitchell and it was limited on the R & R on this one.

Do you have the catalog #'s for the gasket kit, o-rings and drier? I can only see up to model year 2000.
