• EPDM construction for heater and coolant service
• Small inside diameters: 15 mm (0.61 in) and 19 mm (0.74 in)
• Centerline length: 269 mm (10.6 in)

Product Details

Built for vehicles with smaller, tighter-fitting engine compartments, this molded heater hose follows the factory path to help maintain proper hose routing and connection alignment. The EPDM construction supports use in coolant, water, and air systems, and the molded shape helps match the original layout on applications such as the Ford Crown Victoria, Mercury Grand Marquis, Mercury Marauder, and Lincoln Town Car. Gates 18069 is a direct-fit style replacement for the specified heater hose routing and is also approved for marine applications.

This part cross-references Continental 64122 for the same application.
