Keep engine coolant moving to the heater core with the Dayco Molded HVAC Heater Hose 87825, a direct-fit replacement for the 2002-2005 Dodge Ram 1500 with the V6-3.7L and V8-4.7L engines. This molded, branched hose carries hot coolant between the engine and the heater core so the HVAC system has the flow it needs, routing along the pre-formed bends of the original.
A heater hose that is cracked, swollen, or leaking can let coolant escape and reduce heat at the vents; if a failed heater hose is the cause, this replaces it. Inspect the cooling system and confirm the source of any leak before installing.
