My friend and I were doing some routine maintanence to the truck the other day, and he mentions to me "Hey man, I dont recall every hearing your fan clutch engage" after we did some test drives... so we let the truck idle for 20min or so, reved it to 3k RPM for a few minutes, etc... sure enough, the fan never engaged.

When the truck is off, the fan can spin freely, almost as if it is on bearings and has very little resistance. Shouldnt the fan not be able to turn when the truck is not running?

Motor: 4.7

Also, I know there is an electric fan on the A/C condenser, is this the E Fan that people refer to checking when their truck is overheating? This confuses me as it is not hooked up to the Radiator, but is on the A/C unit itself.

It appears that this truck has the standard cooling with only a Fan and clutch, no E-Fan on the Radiator?

Seems premature to me for the clutch to have gone out as the truck only has 49k miles.

 

spin the fan by hand, if it goes more than 1/2 a turn replace the clutch,

the efan you have is what they talk about, it is in line with the a/c condensor, but it will move air over both the radiator and evap core, if the truck gets over *210 the e-fan will then come on.

also alot of people complain about the clutch fan engaging on cold start (after sitting at over night) this is normal with a good clutch, it will let go once you get moving (some claim 1/2 mile of driving to get it disengaged)

 

An electric fan is also good for freeing up horsepower,

I dont plan on replacing the clutch fan for an E-Fan, Ive thought about it, but simply prefer the cooling from the clutch system.

The fan spins and spins when the truck is cold, looks like its time for a new fan clutch. Thanks a bunch.

 

...also, I am going to be changing the fan clutch myself.

1. Do I need to drain the coolant? I saw somewhere that coolant needs to be drained, I never had to do this in my Chevy, is this true for the 05 Durango?

2. Can I remove the fan without removing the shroud?

 

i have never heard of needing to drain coolant to replace the clutch fan so the answers should be no and yes

 

Thanks for the answers. I appreciate it.

Still funny to me how good the cooling system is in these trucks, that with a bad fan clutch, and 95* day, the car will BARELY make it to the half way mark sitting in traffic, etc.

...but I digress, its a gateway to a larger issue, and will be fixed.
