Great comments since my recently posted update.
Very interesting info regarding the water pump. My cooling issue certainly could be related to the wrong water pump being installed. Before this discussion, I was not aware of a clockwise or counterclockwise rotating water pump and how it could affect the fan clutch.
I have a Workhorse OEM water pump and a Workhorse OEM fan clutch onboard. They won't be installed until two weeks after I get home. I will closely compare the presently installed water pump with the new one that will be installed to see if their is an obvious difference. I will also install the new fan clutch regardless of the condition of the existing one.
I depart Charleston for Gloucester Virginia Sunday morning.
I will post an update when this work is completed.
Thank you for all the comments.
