The cooling issue is now cured on our ’88 xj 4.0, thanks to the new fan clutch. Pulled the same pass at full throttle much of the time, with a passenger, 120lbs worth of batteries, and the AC was running full blast. Don’t forget the new over sized fan clutch. Outside temp was 85F, which is 25 degrees higher than the last time I charged this pass, with the temp gauge hitting the red. The temp gauge this time hit about one needle tip width past 210. Didn’t have the mt2500 along for an exact number. Cooled right down on the other side of the pass. The old girl did great under full load !!!
Highway testing works great. But it’s a lot more fuel to drive to the nearest incline at freeway speed.
The oversized fan clutch from Napa, is recommended online in at least one forum. Plus we need better cooling out here in the desert heat south of Vegas.
The radiator grenaded !!!
Having to fold my own staples made this whole plastic welding process very strong, and well worth it !!
