could someone pls advise as to the max operating temperatures for an SR 5 4x4 extended cab truck, with the 20R engine. It is a first generation EFI.
I had a new temp gauge installed and it registers 230 deg. coming up a 6000' grade in the mountains at 55-60 mph. My AAA rated mechanic states it should not exceed 210-220. So this concerns me. The truck is fully tuned- has a new thermostat- new belts- the fan has been checked and the radiator flushed and has new coolant.
Once in the canyon it starts to descend to the about 220. There is seemingly no loss of coolant.
??
thank you
