Radiator hose adapter


Man. My champion aluminum radiator with three electric fans is awesome. Never goes above 180.But what a headache for me. To me it was a lot of work but was so worth it. First generic aluminium one from amazon fit good exept for the tranny line. I return it Because the fitting lines were made of cheap brass and sucked. But you would probably plug yours of because you have an external tranny cooler. Ialso had to wire in a dual relay system with electronic temp sensor. I wired two fans to the relay system with a manual bypass switch under the dash and the third fan that turns on with the a/c. There were no more openings for the new temp sensor for the relay system .so I had to get an in-line 30mm upper radiator hose adapter. It has a 1/8 npt thread. See pic. I also found a 180 off and on sensor. The champion one I got needed radiator support mods but that was just a matter of cutting it down across the top and around the cap.and I had to remove the studs and use bolts on my serpentine belt tensioner Because it hit the electric fans. Like the previous guy said. Replace the water pump, thermostat,upper and lower hoses ,cap and flush the system. Make sure you use the correct temp thermostat I didn’t the first time.If you do flush your system, use the prestone flush. I used an heavy duty cleaner in my 1996 and my heater core started leaking because the heavy duty chemical flush ate up the heater core. I would also get a new clutch for the clutch fan. I had two Cherokees that got warmer under load then I wanted. Both clutchs were hard to tell but were slightly going out. Once I replaced the clutch I never had a problem again.Hopefully you or someone else can use some of what I wrote.

I have to agree that a good quality stock $120 radiator is sufficient enough for most. Not for me. But for an extra $250 and about 4 hours of labor. It was so worth it to me. You always run into snags along the way. That’s four wheeling. At least I got a refund on on my crappy radiator and only lost about $50 and a couple hours because I went to cheap.The nice part about it is I just brought my cherokee out of the Stone Age. I have never liked dealing with clutch fans and plastic fan shrouds. Freerder15,I don’t know why you are saying that a constant 180 degrees is inefficient. We can agree to disagree. All my jeep Cherokees I have owned ran between 195 and 200. My jeep runs way better at 180. But that 180 is during the winter. Nothing under the hood gets as hot now. I used to be able to fry an egg on the hood and when I ran it for a couple hours, I would almost burn my hand trying to open the hood. That 15 to 20 degrees make a big difference everywhere.

This is hard one to fix.
