Hi all
Well I think the clutch fan is shoot but I don't know it gets hot climbing hills and siting in traffic is it OK to get rid of the fan and run duel electric? Could the t state be bad? I dont know what makes a diesel run hot I'm new to this so any help would be appreciated (or any info on how I can hop up the pump) or ? thanks all

 

sounds like a clutch fan but i would also throw a t stat in it as well the electric fans are good but not so much for pullin if you tow hope this was helpful

 

while sitting in traffic it should not get hot, I would think that you have a thermostat problem. Do not buy after-market thermostats, they are junk (from allot of customers who buy from me, tell me this)
There are two types, if you buy the original, it will have a little tab sticking out from the side, you have to align that correctly in the housing or it will not vent correctly, then there is the adjustable kind, they do not have a tab and do not need any aligning for them to work correctly.

 

Thanks for the help I went the smart way and got a stock t stat from cummins and some good duel electric fans and got just got rid of the fan hope it works
