FOR ALL JEEP 2000 6 /4 liter ?i have successfully won the overheating battle with my jeep 2000.here is the solution.Based on some suggestions posted on this forum I have installed:
2 row ready rad for 119$,from DIY radiator(do not believe you can run flow test on your rad and hope its good.10 years old rads have deposits in them you can't see.For 119$ do yourself favor and toss old one in the garbage)
1993 ford explorer plastic 10 blade fan mounted on original jeep clutch(needs very little alteration )
185 thermostat-not necessary you can use 195
My gauge is steady in hot 89farenheit .it stays just about 1/8 of an inch below middle.even under heavy load up the hill.
Thank you all for your recommendations.
