Thermostats is my best guess. Good luck J-Trucker.
-
Well I will update u what we find out.. Will that make me lose power?
-
Well got it back and Thermostats and bad and radiator cap was bad as well. So runs good now but need to take back and see what code is coming up because the engine light come on and off sometimes but I do not lose power. Dose anyone know how ofter fan turns on and off when park?
-
Fan cycling depends on wether or not a/c is on. A/C will make fan cycle regularly.
-
Ok thanks when park at night should I keep fan on all the time or let it cycle?
-
Do you idle the engine up or let it idle at low rpm's?
-
It at 800 rpm just so my truck will not turn off
-
I would leave the fan on all the time just because at that rpm the fan is pretty loud. Leaving the fan on all the time at least allows you to get used to the same constant sound.
