Forum Discussion
The dash board says it's overheating...why do you believe it's not overheating?
It wouldn't be unusual for a marginal coolant system to be fine under light load but pull an 8000lb trailer up a steep grade in 110F, it struggles to keep the engine cool.
Running light on flat ground, it may only take 60-70hp to run at freeway speeds and even if the fan clutch doesn't kick in, there is a 60-70mph breeze blowing the heat away.
Change that to pulling an 8000lb trailer up a steep grade doing 20mph, you might be pulling 3 times the power and the breeze is pulling away far less heat at 20mph.
Too many questions to do anything other than speculate. To help:
- Provide the truck specs. (engine, tow rating, payload, year, etc...)
- Provide the trailer specs (model, GVWR, any unusual modifications)
- Provide the conditions where you experience the issue (Speed, grades, temps, etc...)
