Should my fan spin @400 RPM when engine is warming up?
I have been searching but can't find the answer (maybe I'm search challenged). I think it is normal but I have read about wire chaffing, short circuits and I'm kind of paranoid. I had a week thermostat and temperature stayed at about 180 degrees (unless I was towing) and the fan was always running around 375 to 450 RPMs and 0 on the fan DC% when driving around town unloaded. I thought that was odd so I'm asking the great FTE comunity for some help.
I never checked the fan speed or fan DC% when towing so I have no idea what the max. RPMs the fan can spin when towing. What is the max RPM's and fan DC%'s? I'm using a Dashboss to monitor my truck.
