I drive my truck 90% of the time empty. Being below 30deg. I installed a winter cover so that it would heat up quicker and run closer to operating temp. Since I installed the Mopar frt cover (half closed) I hear the clutch fan more often than before pulling out from stops, But the temp guage is still at or below the normal range (just below the 200deg. mark) I dont no if the fan noise is just more noticable now with the cover or why is the fan running.
