Heater core hose.

Anyone have the part number for the hose that goes from the radiator to the heater core?

What vehicle are you working on? Year, make, and model is very helpful in answering these questions, since there are at least 3 different versions of radiator hose routings used on the 6.5L engines over the years.

I had trouble locating that hose when I replaced mine recently as well. Turns out Dayco 87740 is a perfect fit:

This fit like a glove on my 1995 K1500.
