Dayco Engine Coolant Bypass Hose,HVAC Heater Hose P/N:87661
Dayco 87964 heater hose for the 2009 Subaru Outback H4 2.5L carries engine coolant between the pipe and the thermostat. This Dayco heater hose, also listed as an HVAC heater hose, is the hose for that position in the coolant circuit.
A failing heater hose can show up as coolant seepage at the ends, a cracked, soft or swollen hose, or coolant loss. Those signs can start elsewhere in the cooling system, so with the engine off and cool, look over the hose and its ends for cracks, soft spots and wet residue, and find where the coolant is going before you replace it.
This hose is a direct-fit replacement for the 2009 Subaru Outback H4 2.5L, which takes one.

How can I tell if the heater hose at the thermostat pipe is leaking?
