I was reading on the site about temps vs. fan engaging......unfortunately there is no set answer. I have owned my truck for over 4 years and have pulled a camper the entire time I have had the truck. I have NEVER heard the fan engage 1 time. I can see it spin when the truck is idling, but I have pulled my camper with my Dad's truck(06, 6L) and his fan would engage while pulling up longer hills. I have a programmer and last time I pulled the camper up some long grades the highest temps were: oil 224, Coolant 221, trans 179. I was pulling a good sized hill and it was 97* outside, but I would have thought the fan would engage. I haven't seen that code again and I only saw it once.A long time ago I had a code for the Fan Sensor, but that was 2.5 years ago. I dont puke coolant, new oil cooler, no egr/cooler( I still have the egr installed and hooked up), truck runs great, pulls great, no smoke.....I am hoping I am just worrying for nothing, but I find it odd that I have not one time EVER heard the fan engage. I have also checked the wiring to the fan clutch and all is intact after reading about 03's and fans chopping wires.
