Motorcraft HVAC Heater Water Hose

The Motorcraft HVAC heater water hose (also called a heater hose or coolant hose) carries engine coolant between the engine and the heater core. This lets your vehicle's climate control system deliver cabin heat and defrost. Motorcraft is Ford Motor Company's genuine parts brand. Its hoses are engineered to meet Ford's original equipment standards.

Key Features:

• Made to OE-level specifications for a dependable fit and consistent performance
• Flexible, reinforced construction that resists heat, pressure, and engine bay vibration
• Designed to handle continuous exposure to hot engine coolant and under-hood temperatures
• Helps maintain steady coolant flow to the heater core for reliable cabin heating and windshield defrosting
• Backed by the Motorcraft name, a trusted brand for Ford, Lincoln, and Mercury service parts

Over time, heater hoses can harden, crack, swell, or leak because of heat cycling and age. Replacing a worn hose helps prevent coolant loss, overheating, and loss of cabin heat. Select the specific part number for your application from the options listed on this page.
