airspeed Posted May 9, 2010 Share Posted May 9, 2010 I have a 88 w/2.5. Trying to install new hoses between the heater core and the heater control valve, these hoses are about 3" long. The heater core outlets are .750 & .625, the inlet on the control valves are both .625. There is a special p/n for the for the reducing hose 52003887, Jeep says it has been discontinued. Has anybody woked this issue before? I'm thinking I maybe able to sleeve the .625 outlet up to .750, not sure what I would use. Link to comment Share on other sites More sharing options...

Blue XJ Posted May 10, 2010 Share Posted May 10, 2010 I ordered the adapter from Summitracing. it slips over the smaller tube, to make it the same size as the larger one, so the larger hose works on both. I think it was <$10. Link to comment Share on other sites More sharing options...
