I give up! I've been using the search engine it seems like forever which has never worked for me even if I only put one word in the search.

Where do I find the source and part number of the 7.3L PSD upper radiator hose that goes around and behind the serpentine belt instead of through it. I'm going to install a 203 degree thermostat in a few days and I figured this would be a good time to replace the upper radiator hose.

Yeah I'm going to flush my whole cooling system, change hoses, and install the 203* Thermostat and Billet Aluminum Thermostat Housing from Bob Riley of Dieselsite. I'll then refill with the same Low Silicate Fleetguard P/N CC2835 ES Compleat Extended Life Propylene Glycol Antifreeze/Coolant 50/50 Premix that I've been using for years. It comes with the DCA-4 already in it to maintain the SCAs to a 2.5 level.

I'd add Bob's coolant filter too........
