I have a problem with my fan clutch. I noticed that when my truck is not moving or when it is driving up the hill my fan clutch does not turn on. The temperature gets up to around 220 and higher. The only time fan clutch turns on is when the Air Conditioning gets turned on, therefore my truck does not gets overheated. I did not change any parts yet, i am not sure what to change. How can I fix this problem? What should I check for?
Just replaced temperature sensor, but the problem is not fixed.
When I started truck today , fan turned on for 10 minutes and then turned off. When the temperature got above 220 the fan never turned on again.
I don't think I have ever heard the fan running other then for the A/C on my truck, even when pulling my camper up hills in the SC summer heat. The ecm can engage the fan at lower percentages for engine cooling and you won't hear it. The only time you hear it is at 100%.

Well i used to never got over 200 on the stock Gage. now going up small hills with the camper in it ( put it in today) It goes about 1/8 inch above 200 (220 maybe) I drove down from Alaska to Utah and going up hills even in the dead of winter i would here it kick on. Now the only time i really here it while driving is when i first start up and leave the house. I also downloaded the computer and the fan clutch fault is gone now so i guess that is good.
Is there a service manual online somewhere to get a schematic?
