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.

The 18826 part is part of this line, providing a molded solution tailored for HVAC systems in various GM vehicles.

Detailed Product Description

The Gates Molded Heater Hose 18826 is manufactured from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. Both ends of the hose have an inside diameter of 0.62 inches (16 mm), making it suitable for standard heater core and engine connections. The molded construction maintains the hose’s shape and routing, with a centerline length of 19.3 inches (490 mm) to fit specific HVAC configurations.

  • Preventing coolant leaks that cause engine overheating or heater malfunction
  • Maintaining system integrity in vehicles with molded hose routing requirements
  • Ensuring compatibility with factory HVAC hose connections

Installation Notes and Tips

When installing the Gates Molded Heater Hose 18826, ensure the vehicle is cool and the cooling system is depressurized. Verify the hose routing matches the original to avoid kinks or interference with other engine components. Use appropriate clamps to secure both ends of the hose firmly. The molded design simplifies alignment, but careful handling is recommended to prevent damage during installation.
