Gates Molded Heater Hose for Tight Engine Bays
The Gates 12518 molded heater hose is a factory-molded, OEM-style coolant hose built for smaller, tighter engine compartments. It is made from EPDM and is approved for coolant, water, air, and marine applications.
Compatible with 2021-2022 Ford Mustang Mach-E reservoir to radiator routing, this molded heater hose supports clean hose routing where a straight hose will not follow the factory path. The Gates Molded Heater Hose line is focused on OE-style fitment for modern vehicle packaging.
