Hi Gang, I got an overheating issue that started a few months ago, and I am chasing it.
The problem only happens when running at highway speeds; when I slow down, temp returns.
Even on hot days, stop-and-go traffic has no issue, and the gauge stays at 1808.
When I say hot, it reaches 220*, then I must slow down.
This is unloaded and not towing.
I have changed the thermostat to a 180* and changed the drive belt (I thought it might have been slipping); I figured that the fan must be OK, as I don't have the issue in traffic.
The motor doesn't lose coolant, and the oil isn't contaminated.
Any thoughts would be most welcome!
Thanks,
Cam
