any one have any ideas why my gq 4.2 diesel patrol might be over heating? I know a 7 inch lift and 35's wouln't help much but someones got to have solved this problem before. It only happens on long up hills.around town and offroad is ok even on hot days.
many thanks guys.
Mate I had the same problem, the rad and cooler in front of it was full of crap and knackered, had it recoed and all cleaned up, now the guage hardly moves once its warm no matter what I do. I would start by pulling it out and giving it a close inspection to see if its stuffed. Hope that helps!

possibly anymore info?
what have you tried to fix it?
its a 6 inch spring lift with a 30mm coil spacer. took me about 1h to fit, all the angles etc seem to be fine and there is no vibrations or anything like that. I wanted the option of being able to lower it for a trip to fraser or something like that.
have replaced viscous fan, flushed radiator and renewed hoses. think some of the fins on the radiator are damaged, so it might need recoring. hopefully, that should fix it.
i want to fit a snorkle for obvious reasons. plus, i have been told that it will make the engine run a little bit cooler.
