2008 Toyota tundra overheating and fifth and six gear while towing
2008 Toyota tundra overheating and fifth and six
gear while towing... when I'm not towing fifth and
sixth gear is totally fine and normal . But when I'm
towing my trailer when I hit fifth or sixth gear my
water temperature goes up to make it go down I put
my truck in manual mode and go to fourth gear and
it comes down back to normal
You might be lugging the engine. I always use lower gears when towing, especially on any kind of grade.
You might want to install a heavy duty radiator.
