Does a guy need a meter to check his exhaust temperature.And turbo boost. I notice my heat goes from 180 to 215 when I get on steep grade. Isx 600


215 is higher than I would want to see. I've climbed most passes out west and 205ish is as high as I've seen. But I'm heavy & underpowered so I downshift early & often. I have been in 3rd gear reaching the summit of some of the bad ones.

Agree.

At around 205, you need to be looking at "Plan B" to keep the coolant temperature from continuing to rise.

Basically, find a gear where you are close to the high end of the engine's RPM range. Throttle position short of WOT. Said another way, if you floor it, you can still accelerate.

If pull out available, put transmission in neutral and engine RPM around 1,200. Unless you have a coolant leak causing the overheating, engine temperature will quickly return to thermostatic control.

If not able to pull over, before chancing an engine failure/derate, turn on dash heater to full hot and fan to high. Think of this as an auxiliary radiator. Better for you to be hot for a few minutes, than be stuck at the side of the road and with a significantly lightened wallet.
