My XJ is running a bit hot - I'm in Arizona, and when it hits 117, it's not fun... And yes, I know everyone will say the stock cooling system is adequate if everything in the world aligns properly; but the fact of the matter is, the jeep was really neglected before I got it, and before I go with a massive overhauling of the engine, I'd like to add a bit more cooling capacity.
The head has been swapped with a TUPY head, so the top end is nice/new/clean. The bottom end for this thing is probably still filthy as all sin (jeep had massive amounts of sludge in it - thanks previous owner). I imagine the radiator and coolant passages in the block are not squeaky clean either... and despite flushing the whole thing, I don't think I can get them factory new clean without replacing components.
The temp will creep up past 210 in stop and go traffic. The fan clutch works as it should right now; so there's no reason to suspect that as the reason. I would still like to do the ZJ clutch swap and when I do, I would like to go with a bigger 3 core radiator. May do a higher flow water pump as well while I'm in there. The only piece that leaves to swap out is the derpy looking mechanical fan 5 blade setup.
I'm not a "fan" of the flex-a-lite stuff, but would like something with more than 5 blades/that moves more air. I don't care about the increased noise.
I've read on the grand cherokee forums about them using the GM 11 blade plastic fan. I have not found a single post of anyone attempting to put that on an XJ - do they fit?
If not, any other fans that fit in place of the 5 blade that move more air? From the looks of the 5 blade setup, it shouldn't be hard to improve on it...
