thanks for the help and sorry for the confusion. It was the eng temp bigcountrysg. I was thinking of the oil when writing the post and at what temp would it start to cook the oil.
So how do I check the fan clutch to make sure it's working.
It seems like the problem is worse when I'm starting to work the truck.
I'm going into town today without the trailer so I'll see what happens today.
The only bad thing is that it is only suppose to be 28 degree Celsius or 82.4 degree Fahrenheit, which is a lot cooler than yesterday.
