With the truck cold, I tried to spin the fan. It doesn't "spin", but I can easily turn the fan blades one by one. There is no movement forward or back or side to side.
When I get into town the truck should be at normal running temp. I'll check everything when it is warm.
No signs of any coolant or leaks either.
Next day I drove it to town. No problems........ ran like a top
A buddy of mine said it could be the fan clutch sensor. I'm going to check the codes this weekend to see if it comes up.
He had the same deal happen to him. AND, when he replaced the sensor and started pulling, he said you could here the fan when it was starting to heat up. I don't notice any "fan" sound. never have. He said it would be pretty noticable.
What else can I do to check the fan clutch?
