My fan likes to howl a lot. How long should it normally take to turn off? I'll take off to go somewhere @ 2AM when it's damn cold and the fan will run for about four minutes. Isn't it supposed to run only when it's hot outside?
do you have a clutch fan? my bronco came with a flex style fan that was always spinning. that mother ****er was noisier than my flowmaster. do a search, i think someone posted how to tell if your fan clutch is toast.
If you don't have an electric fan,or flex fan,it's probably fluid filled.It adjusts itself with temperature.I've had 2 go bad on my 95.If it's the stock one they're easy to change,4 bolts holding it to the water pump,and 4 blts holding the fan to the clutch.
