Cheers,
I was having trouble with mine last summer but i never knew because the factory temp gauge didnt move much. It wasn't until the tuner plugged it into his pc and took it for a drive (diagnosing another problem) we noticeed it around 90 degrees). Since then i have played with the clutch fan and have noticed a lot more air being pulled through.....i just have to wait until its back on the road!!!!

PS: I also have a 4.2EFI patrol that is nearly identical in the engine bay minus the turbo. I plugged my consult thingy in and noticed when the factory gauge is on 1/4 its 84 degree (sits there on normal driving) and 1/2 is 89 degrees!!!
