Keep coolant moving between the water pump and the rest of the cooling circuit with the Dayco Coolant Bypass Hose 72516. This curved hose drops in as a direct-fit replacement for many vehicles, among them the 2005-2008 Ford Escape 3.0L, 2006-2009 Ford Fusion 3.0L and 2003-2008 Mazda 6 3.0L — see the "Vehicles it fits" section for the full list of covered applications.
It carries engine coolant through the water-pump routing (water pump, engine-to-water-pump, and water-pump-to-intake-manifold positions), so a cracked, swollen or leaking original can leave you with coolant loss and overheating.
- EPDM construction: EPDM material built to SAE J20R4 Class D-1 and SAE J1684 Type EC.
- Curved single-I.D. design: pre-shaped hose with a 1.50 in (1 1/2 in) inside diameter at both ends and a 6.5 in centerline length.
- Finish & details: black, with no heat shield and no protective sleeve.
- Country of origin: Mexico.
Signs the original may need replacing include soft or swollen rubber, surface cracks, coolant seepage at the connections, or a low-coolant/overheating condition traced to this hose.

It fits many vehicles, among them the 2005-2008 Ford Escape 3.0L, 2006-2009 Ford Fusion 3.0L and 2003-2008 Mazda 6 3.0L. See the "Vehicles it fits" section for the full list.
What is this hose made of?
It's made from EPDM and built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications.
What size is the Dayco 72516?
It's a single-I.D. curved hose with a 1.50 in (1 1/2 in) inside diameter at both ends and a centerline length of 6.5 in.
Where does this hose connect?
It routes coolant in the water-pump area, covering the water pump, engine-to-water-pump, and water-pump-to-intake-manifold positions.
How do I know if my engine coolant bypass hose needs replacing?
Look for soft or swollen rubber, cracks, or coolant seepage at the connections. If a leaking or failed hose is the cause of coolant loss or overheating, this replaces it.
