I have a 2001 magnum 325 and the fan comes on all the time if you drive 500 feet it is on ...So I changed the oil and filter but still the same thing!!! but now the oil & the fan come on.. when you only drive 40 feet ... the oil is good and when I pull the dipstick the oil isn't even really warm...any idea's ???

 

maybe your sensory for the fan is bad?

 

Chech your radiator to see if it is stopped up with mud or something.Then check your sensor.

 

how do you check the sensor??? is there a way to tell if it is done??
