Yesterday I was able to buy the upper radiator hose (off water pump) at O'Reilly's. I was surprised they had it. It is a Gates item with the new white upper end and double O ring design. $54.00. I will begin the installation task later this week maybe next weekend when weather goes 70+ again.
I will be reviewing coolant filter systems this week as well. I have never owned a Ford (IH) diesel. I have been a Dmax owner since 1999. Never had issues like this so I really appreciate the help I have received from this forum. Thank you!
