I wish more gq owners used accurate temp gauges to compare with... i run a good digital job and find it much better than the dodge factory one.

Mate I reckon that's actually your biggest problem to be honest. You were concerned about seeing 90 on your gauge on the snow trip. No one else was bothered at all. Your Nissan gauge would have shown very little change and everything you were running was well within spec.

Your engine will take 100 any day, and all day mate. Mine runs around at just under 90 but sees a rise on big hills. I vote for replacing your radiator and going for a drive. You are letting your water Temp gauge smash your head in mate.

Matty is suggesting having the face of the pump housing machined off by upto 3mm to bring the impeller closed to the block to restrict blowby on the water pump. I run a Nissan Pump on my GQ, when it sh1t itself I replaced it with another Nissan one. Decent coolant will happily run at 110 safely, that's the point of not using Water to lift the boiling point and allow safe operation on your engine at its upper limit.
