What It Helps Fix

• Coolant leaks from cracked or aged molded hoses
• Softening, swelling, or collapse in heat-cycled hose sections
• Poor hose routing after prior repair work
• Restricted coolant flow caused by hose deterioration
• Heater circuit service on vehicles using a formed hose path

Installation Notes and Tips

Verify end diameters, centerline length, and hose routing before installation. Compare the original hose shape to the replacement and confirm the application position, such as Heater To Tee, Heater To Tee-1, or radiator/HVAC routing, before final assembly. Inspect adjoining tees, clamps, and pipe ends for corrosion or damage so the new hose seals correctly.
