Dorman - OE Solutions HVAC Heater Hose Assembly P/N:626-626
Dorman 626-656 heater hose for the 1999-2002 Dodge Ram 2500 6-cylinder 5.9L and other vehicles carries engine coolant to the heater system. This Dorman heater hose assembly is molded to shape, and each end attaches to another hose.
A coolant leak, a cracked or swollen hose, or a heater that stops warming can mean a heater hose is wearing out. These signs alone do not prove the hose is at fault; a stuck thermostat can also leave the heater cool.
This hose directly replaces the original heater hose on the 1999-2002 Dodge Ram 2500 6-cylinder 5.9L and the 1999-2002 Dodge Ram 3500 6-cylinder 5.9L. Each takes one, and this listing is one hose assembly.
