Does anyone know what is hottest but safe running temperature for a 1GGTE?
I'm about to drive to Darwin from Alice and the day time temperature will be in some parts 45c+.
I think the thermostat temp is about 82 degrees. I have my thermo fans cutting in at around 90 degrees.
The factory thermo fans on the GZ20's cuts in at closer to 100 degrees.
As for the maximum, push it at your own risk. If it gets hot then drive easily and if it still gets higher shut it down.
I would get the cooling system flushed before the trip and make sure it is in good health. While your driving it should keep at reasonable temps, it is idling on a hot day that will kill it.
year before last i drove back from byron to sydney, day before dyno day in my 28 with a 1g with a very undersized radiator. basically the needle would climb is i put the foot down and came on boost, so i just putted home.
