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 Buyer's Guide tab 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.
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.
