T660 lower water tube

[Squish099]

Over the last few days me and Rawze have had quite the experience with this lower water tube debacle. The original water tube (Paccar part #F66-2281). The heater core return is 90° to the tube pointed toward the passenger side. The new lower water tube (same part # as far as I know) the heater core return is inline with it facing forward.     Now the heater core return will not work.    . We couldn't find the correct mold hose from Paccar. Had to make it work. Ordered a molded 90° silicone elbow from summit racing (part #sum-294040) and 1.25" flared hose connector (part #sum-380600)   
To remedy Paccar dropping the ball. Everything has to be trimmed to fit.     When finished the water heater core return should be a 90° down under frame rail then 90° back    . This was a huge headache costing me a day, getting truck back together, costing Rawze a bunch of time also.

Looking back at those pictures, it looks like it is in the way for replacing the water filter too. It is a good thing you put a new one on before replacing that hose.

Could probably cut the black hose a little shorter and it would be closer to lower water tube could possibly get out of the water filter
