LOL! XJ running too COLD

the ultimate solution for an overheating XJ
new alum rad
switch to electric fan - but don't even bother hooking it up
run 27" tires with 4.10s

oh yeah, and......drive in -23 C temps.

I can't believe I'm going to need to put a winter front on my XJ to block the cold air from the rad. I can warm it up to 100 C in the driveway (long enough that tstat has opened, temp dropped, then climbed to 100 again) but as soon as I drive away the temp plummets. I am convinced that this is because of the excellent heat dissipation properties of the alum rad.

thermostat, it could be sticking, replace it with a 180 or 210deg one

long thread in the stock tech forum. look there.

sorry guys, wasn't complaining or anything, just commenting. I know about the overheating problems plaguing our XJs and I redid my cooling system last summer and the solution for me was the new alum rad. Just commenting on how much more efficient they are at dissipating heat, that's all.
