Water Pump Gasket 14-02 Chevy 5.3L 6.2L

The Water Pump Gasket 14-02 Chevy 5.3L 6.2L is an OEM-quality replacement seal engineered for General Motors Gen V LT-series engines, including the LS3-based 5.3L and 6.2L variants found in 2014 and newer Chevrolet trucks, Camaros, and performance builds. This gasket is critical for maintaining a watertight seal at the water pump mounting surface, preventing coolant leaks that can lead to overheating, engine damage, and costly repairs. Whether you're performing routine maintenance, addressing a weeping pump, or rebuilding a high-mileage engine, this OEM-specification gasket ensures reliability and longevity.

Manufactured by MAHLE ORIGINAL/CLEVITE—trusted suppliers of OEM and aftermarket cooling system components—this water pump gasket features a robust steel core with a 0.019-inch thickness and black composite facing designed to compress uniformly and maintain seal integrity under thermal cycling and pressure fluctuations. The steel construction resists chemical degradation from modern coolants while the composite surface ensures a perfect mating surface against both cast-iron and aluminum pump housings. The precise dimensional profile (6.05 × 8.25 inches) guarantees correct bore alignment and port registry, eliminating the common problem of misalignment that can compromise the seal on aftermarket or universal gaskets.

This gasket pair is essential for engine builders, performance enthusiasts upgrading cooling systems, and mechanics replacing water pumps on 2014-and-newer Chevrolet 5.3L and 6.2L engines. Installation requires only basic hand tools and coolant drainage; proper torque sequences prevent over-compression that can damage the gasket face. For turbo builds, LS swaps, or high-horsepower applications, using OEM-specification gaskets like this MAHLE product eliminates variable failure points and ensures consistent coolant circulation under stress.
