Detailed Description

Gates 21575 is a molded radiator coolant hose designed for upper cooling system use on specific Ford, Mercury, and Lincoln models. The EPDM rubber construction is suited for coolant exposure, while the molded profile helps maintain the factory-style hose path and connection points. This makes it a practical replacement when servicing an aging or damaged upper radiator hose on vehicles such as the 1987-1991 Ford LTD Crown Victoria, 1986-1991 Mercury Grand Marquis, or 1986-1990 Lincoln Town Car.

As part of the Gates Molded Coolant Hose line, this hose is built around replacement-market coverage for upper, lower, bypass, heater, and other coolant applications. Part number 21575 is also cross-referenced with Dayco 71303 for the same application.
