Product Details

Gates 18770 is part of the Molded Heater Hose line, which focuses on OE-style hose routing for vehicles that need a formed replacement rather than a straight universal hose. The molded design helps match the original path in compact engine compartments, supporting proper hose alignment in heater and coolant plumbing. This part cross-references Dayco 87647 for the same application.

Compatible With select 1989-1990 Chrysler Daytona, Chrysler LeBaron, Chrysler Shadow, Dodge Daytona, Dodge Shadow, Dodge Spirit, Plymouth Acclaim, and Plymouth Sundance applications. It also covers 1989 Chrysler Phantom, Chrysler Daytona, Chrysler LeBaron, Chrysler Shadow, Dodge Aries, Dodge Lancer, Dodge Daytona, Dodge Shadow, Plymouth Reliant, and Plymouth Sundance routing shown in the fitment data. Gates 18770 is a direct search match for buyers looking for a molded heater hose for Chrysler Daytona valve to water pump, Dodge Shadow heater hose replacement, or Plymouth Sundance coolant hose routing.
