What It Helps Solve

• Coolant leaks at a molded hose section
• Poor hose routing from a damaged original hose
• Replacement needs for upper or lower cooling-system hose service
• Fitment issues on select Ford, Buick, Oldsmobile, and Jeep applications

Installation Notes and Tips

Verify end diameters, centerline length, and molded shape against the original hose before installation. Confirm whether the vehicle uses an upper or lower hose position, since fitment varies by application. Inspect clamps, thermostat housing connections, and radiator necks for wear before installing the new hose.
