Keep coolant circulating to the cab's heater core with the Dayco heater hose 88501, a molded rubber hose that drops in as a direct-fit replacement on the 2011-2014 Ford F-150 equipped with the V6-3.5L engine. This branched hose carries engine coolant between the cooling system and the heater core, and its pre-formed shape holds the routing needed to clear engine-bay obstructions. As a Dayco hvac heater hose, it serves the heater outlet position on the listed application.
If a cracked, swollen, or leaking original heater hose is behind a coolant smell, low coolant, or weak cabin heat, this replaces it. A Dayco 3 4 heater hose search matches the 3/4-inch end of this assembly.

This part cross-references / interchanges with the following part numbers:
What vehicle does the Dayco 88501 fit?
It's a direct-fit replacement for the 2011-2014 Ford F-150 equipped with the V6-3.5L engine.
Is this a Dayco hvac heater hose?
Yes—it's a molded heater hose that carries engine coolant to and from the heater core, feeding the cabin heat circuit.
What are the hose end sizes?
One end has a 0.75-inch (3/4) inside diameter and the other a 1-inch inside diameter, so a Dayco 3 4 heater hose search matches the 3/4 end.
What does the "branched" molded type mean?
It's pre-formed in a fixed, branched shape that routes through the engine bay to the heater outlet position, rather than a straight length of bulk hose.
What are signs this heater hose may need replacing?
Cracks, swelling, or a soft feel in the hose, a sweet coolant smell, low coolant, drips, or weak cabin heat can indicate a failing hose; diagnose the source before replacing.
