Genuine BMW Water Hose Assembly

The Genuine BMW Water Hose Assembly is an original-equipment engine coolant hose (also called a coolant hose or heater hose assembly). It is a multi-port assembly that carries coolant between the expansion tank, the thermostat and the heater circuit in the engine cooling system. Replacing a cracked, leaking or worn coolant hose helps protect the engine from coolant loss and overheating.

Key Features:

• Genuine BMW part: built to the same specification as the original factory component
• Multi-port assembly: a single pre-formed unit with several connection points, which replaces separate hoses and simplifies routing
• Coolant circuit service: links the expansion tank, thermostat and heater hose connections
• Replacement part: restores sealing and coolant flow where the original has aged, become brittle or started to leak

Using a genuine BMW assembly helps you get the correct shape, connection layout and quality for a dependable, long-lasting repair. Inspect the clips, connectors and nearby cooling components when you replace the hose, and refill and bleed the cooling system as BMW specifies.
