MississippiComanche Posted March 26 Share Posted March 26 I need a new water pump for my 1987 Comanche 2.5. Any particular water pump brand I should look for or are they all the same? Link to comment Share on other sites More sharing options...
eaglescout526 Posted March 26 Share Posted March 26 I know we’re probably looking at me, but I have nothin. I have a mopar pump on mine. I used I think an airtex years ago and it was fine. No issues with it. Link to comment Share on other sites More sharing options...
MississippiComanche Posted March 26 Author Share Posted March 26 Eagle do you know if the non-ac bypass has a reverse water pump rotation or is it standard rotation compared to the ac version? Link to comment Share on other sites More sharing options...
eaglescout526 Posted March 26 Share Posted March 26 It’s still standard. I didn’t have to change mine out when I added AC Link to comment Share on other sites More sharing options...
Spinnakerblue89 Posted March 28 Share Posted March 28 I would like to throw my 2 cents out there. Currently I am doing a water pump+heater line replacement on my '93 ZJ Laredo, 4.0. I have the GMB kit from Rock Auto that I closed the fan clutch too. I ran into a snag when I was putting the water pump together on Sunday and haven't gotten back to it due to work and a recent freeze (thanks, March...). Apparently, some of the water pump replacements have tapered (pipe) threads, so unlike the original water pump, the inlet hose nut won't fit flush against the unit. I don't know if the 2.5 i4 uses the same part or not but keep in mind that if the procedure is the same as it is for the 4.0, don't get hung up on the inlet pipe not threading on the last 1/3......... ...... So I'm told. If anyone else with experience has any advice to the contrary let's hear it! Link to comment Share on other sites More sharing options...

My mopar units won’t sit flush either. There’s units out there that have a built in inlet and there’s some that don’t. I’ve always despised using the built in one as my MJ does not have that set up, my XJ might though but to each is there own on which style they want to use.
