Keep warm coolant moving to the cab with the Dayco heater hose (P/N 88501), a molded replacement that drops in for the 2011-2014 Ford F-150 with the V6-3.5L engine. This branched, pre-formed hose is shaped to follow the factory routing at the heater outlet, giving you a clean swap for an original hose that has hardened, cracked, or begun to seep.
This molded unit carries engine coolant between the engine and the heater core. If a leaking, swollen, or brittle heater hose is behind low coolant or weak cabin heat, this replaces that hose. Country of origin: Mexico.
