About the Gates Molded Heater Hose Product Line

The Molded Heater Hose line by Gates focuses on delivering hoses that are pre-formed to match specific vehicle applications.

Detailed Product Description

This HVAC heater hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and weathering. Both ends of the hose have an inside diameter of 0.75 inches (19 mm), ensuring compatibility with factory connections. The molded construction maintains the hose’s shape and length, measured at 13.6 inches (345 mm) centerline, which matches original equipment specifications. The hose does not include quick connect fittings or branches, simplifying installation and reducing potential failure points.

Common Applications and Issues Addressed

  • Replacement of cracked or leaking heater hoses in Buick Century and Chevrolet Celebrity models
  • Restoring proper coolant flow in Oldsmobile Omega and Pontiac Phoenix heating systems
  • Eliminating heater core leaks caused by deteriorated hoses in Buick Skylark and Chevrolet Citation vehicles
  • Maintaining consistent cabin heat performance in Pontiac Cutlass Ciera and Citation II
  • Preventing coolant loss and overheating due to damaged or worn heater hoses

Installation Notes and Tips

Ensure the engine is cool before beginning installation to avoid burns from hot coolant. Verify hose routing matches the original configuration to prevent kinks or interference with other components. Use appropriate clamps to secure the hose ends firmly, and inspect all connections for leaks after installation. The molded design of this heater hose simplifies alignment and reduces installation time.
