Gates Molded Heater Hose

The Gates 19280 molded heater hose is an OEM-style coolant hose shaped for tight engine compartments. Built from EPDM and formed to the correct bends, it supports coolant, water, and air routing in service applications.

Detailed Description

This Gates molded heater hose is part number 19280 and is built to match the shape needed in smaller, tighter engine bays. The hose measures 0.62 in. on one end and 0.75 in. on the other, with a 15.1 in. centerline length, making it a fitment-focused replacement for routing between coolant passages and reservoir or pipe connections. It is a practical choice for service work on Cadillac DeVille, Pontiac Bonneville, and Oldsmobile Aurora applications listed in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

Replacing a cracked or softened heater hose
Restoring coolant flow through a molded hose route
Addressing leaks at hose ends or formed bends
Correcting hose routing in compact engine compartments

Installation Notes and Tips

Match the molded shape to the original routing and confirm the connection points listed in the fitment data: Pipe-3 to Pipe-4 or Pipe-3 to Reservoir. Use the part number 19280 to confirm the correct Gates hose before service. For vehicle-specific applications, this hose is listed for Cadillac DeVille, Pontiac Bonneville, and Oldsmobile Aurora models shown above.
