Gates 90-94 Mazda Protege 4-Cyl. 1.8L Heater To Pipe-2 Molded Heater Hose

This is a Gates molded heater hose, part number 18779, designed to connect your heater core to the pipe on a variety of vehicles. It's specifically shaped to fit the routing needs of many 1.8L engines from the late 80s and early 90s, including popular models like the Mazda Protege, Ford Escort, and Eagle Vision. A molded hose like this ensures a clean installation and proper flow for your cabin heating system.

Gates uses a strong, heat-resistant rubber compound for this hose, built to withstand the constant cycling of hot coolant. The molded shape means it follows the factory path without kinking or collapsing, which is crucial for maintaining good coolant flow to your heater core. This helps ensure you get warm air in the cabin, even on the coldest days. It’s a well-built replacement part that fits right into the original location.
