Detailed Product Description

Gates 19672 is a molded heater hose made for vehicles that use a compact, shaped hose path instead of a straight universal hose.

Compatible vehicle coverage includes 1990s and 2000s Chevrolet and GMC trucks and SUVs, plus select Ford, Lincoln, Mercury, Infiniti, Pontiac, and Chevrolet passenger vehicles. This part cross-references Continental 64337 for the same application.

Common Problems This Hose Can Address

• Cracked or leaking heater hose at the factory bend

• Heat-related hose deterioration in coolant service
• Loss of heater circuit flow from a damaged hose
• Fitment issues when a straight hose will not follow the original path

Installation Notes and Tips

• Verify the vehicle position and notes before ordering; fitment varies by heater-to-pipe, valve-to-engine, and valve-to-intake-manifold applications.
• Confirm both hose ends measure 19 mm (0.75 in.) inside diameter.
• Inspect mating pipes, clamps, and nearby components for wear before installation.
• Route the hose to match the original molded shape and avoid twist or kinks.
• Check coolant level and system operation after installation.
