Product Details

Common Problems This Hose Can Address

• Cracked or aged upper radiator hose material
• Coolant leaks at a worn hose section
• Improper hose routing after prior repairs
• Collapsed or softened hose walls from heat exposure
• Fitment issues when replacing a formed OEM hose with a generic hose

Installation Notes and Tips

Verify the vehicle year, make, model, and upper hose routing before installation. Compare the original hose shape, end diameters, and centerline length to confirm the replacement matches the cooling-system layout. Inspect hose clamps, necks, and adjacent cooling components for wear or corrosion before refilling the system.

For 1980-1983 Honda Civic upper radiator and HVAC coolant hose service and 1979-1982 Honda Prelude upper hose service, confirm the hose follows the original formed path without twisting or kinking. Proper routing helps maintain consistent coolant flow and reduces stress on the hose ends.
