What does this heater hose connect?

This molded heater hose connects your vehicle's heater core to the heater pipe. This connection allows engine coolant to flow through the heater core, which then warms the air blown into the cabin.

What vehicles does this Gates heater hose fit?

This hose is designed for 1986-1991 Mercury Grand Marquis, 1987-1991 Ford LTD Crown Victoria, 1987-1990 Lincoln Town Car, 1987-1991 Mercury Colony Park, and 1987-1991 Ford Country Squire models, specifically those equipped with the 5.0L V-8 engine.

What is the benefit of a molded heater hose?

A molded heater hose is shaped to follow the specific routing required by the vehicle's engine bay. This ensures a clean installation without kinks or strain, unlike a universal hose that might need to be bent or forced into place.
