I have a 2001 Dodge Ram 2500 4x4 auto with 121,000 miles on it problem is the fan clutch that I have replaced twice now still stays on. Anyone know why a new fan clutch would stay locked in? Doesn't matter if it's 32 degrees outside or 99 never unlocks engine runs right at 195 because I even changed the thermostat

Maybe because the quality of new parts now a days is awful.
New does not mean good always.

Your 01 requires a 195 thermostat.

What is the problem? Sounds like it is working correctly....

problem is as stated replaces fan clutch twice within two days both with new fan clutchs and both stay on constantly neither of them shut off

When the engine is off and you try to turn the fan does it turn?

Yeah I can turn it but it doesn't spin freely, my 12 valve I can take one fingers and spin the fan this 24 valve Won't. I also changed the water pump with a new 195 t stat, I bought a napa brand fan clutch same thing stays locked n never cycles on and off, I'll just buy the flex a light electric fan and be done with it

Did you check that the little thermostat on the front of the fan can turn it's shaft?
Maybe the little spring (bi-metal) or the shaft got a knock during transport or installation?

johnh

what brand are they? where did you buy them?

The electric fans won't be very efficient on a Cummins.
It shouldn't spin freely, it should feel kinda gummy.
I don't even notice my fan when the truck is running.
At 195, sounds like it's all working...
