Chris-tofer Posted July 12, 2022 Share Posted July 12, 2022 Here we go, been searching, but haven’t found the answers. We are adding a/c to 1988 4.0 that has a remanufactured Jasper in it from a 1995. We got the whole system out of a 1996 minus the under hood wiring and correct idler pulley. Learning quick how parts changed year to year. The “dilemma” we are in is the 1996 compressor doesn’t mount the same as the 1988. There isn’t a idler bracket on the power steering side. Would it be better to buy a 1988 style compressor, or try to source a idler bracket from a later model? I don’t mind buying the compressor, as this one is already older from a junkyard. We already replaced heater core and evaporator under dash. Any suggestions? Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted July 12, 2022 Share Posted July 12, 2022 You can swap to the 96 fan bracket so you can use a 96 compressor and use the 88 belt . You don’t need the 96 idler pulley , the power steering pump will tighten the belt Link to comment Share on other sites More sharing options...

The belt from the ‘88 won’t clear the thermostat and hoses the way it was. Is there an alternate way to route it? Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted July 12, 2022 Share Posted July 12, 2022 I forgot about the idler pulley. You’re right Link to comment Share on other sites More sharing options...

You’re right Would you recommend using an ‘88 style compressor? It would allow for the pulley. This things starting to feel like a Johnny Cash song….. one piece at a time😂 Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted July 12, 2022 Share Posted July 12, 2022 Possibly, I don’t know if the newer hoses would work . Link to comment Share on other sites More sharing options...

I have the newer style (‘96) evaporator, expansion valve and dryer that I bought new. I wouldn’t be opposed to buying new hoses and the older style expansion valve, dryer and compressor if need be. I just want it to be done the most efficient way. Link to comment Share on other sites More sharing options...
eaglescout526 Posted July 12, 2022 Share Posted July 12, 2022 Yeah this could be an issue. You can always swap to the Renix compressor but you might run into the issue of hose fitment like stroker said. Chrysler was pretty non standard with AC parts in HO years. Like 94 could have one hose set and then 95 can have completely different hoses. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted July 12, 2022 Share Posted July 12, 2022 Try a fan bracket/ Idler pulley from a 94ish Cherokee. I believe that should give you the newer style compressor and the older style belt routing Link to comment Share on other sites More sharing options...
Chris-tofer Posted July 12, 2022 Author Share Posted July 12, 2022 What about sourcing a newer style bracket for idler? I left the one on the ‘96 at the junk yard not quite thinking it all through🤦🏻 Link to comment Share on other sites More sharing options...
