Dayco HVAC Heater Hose P/N:87770
Move hot coolant to your cab's heater core with the Dayco heater hose (P/N 87825), a molded, branched replacement built as a direct-fit for the 2002-2005 Dodge Ram 1500 with the V6-3.7L or V8-4.7L engine. This Dayco HVAC heater hose is pre-formed to follow the factory routing, so it seats along the intended path without extra splicing or straight-hose guesswork.
A heater hose routes coolant so the heater core can warm the cabin. Signs the original may need replacing include cracking, swelling, soft or brittle spots, coolant seepage at the hose, or a coolant smell. If a failed hose is the cause, this molded unit replaces it.
