Engine Coolant Hose – Mazda (zzca15536)

Engine Coolant Hose routes fluid through the engine bay or underbody. The crimp or flare is the usual failure point, and it fails from vibration rather than from pressure.

Replace the Engine Coolant Hose when a leak appears at a flare or when the line has been bent close to a heat source. Routing must follow the original path or it will chafe.

Reference number for the Engine Coolant Hose: zzca15536. It is filed under Hoses & Pipes, and it is the number that has to match the part coming off the vehicle.

This is MAZDA dealer-sourced stock rather than an equivalent, so the number on the Engine Coolant Hose traces straight back to the manufacturer.
