Water Pump Gasket 14-02 Chevy 5.3L 6.2L

The Water Pump Gasket 14-02 Chevy 5.3L 6.2L is a critical engine sealing component designed for General Motors' modern small-block and big-block powerplants. Whether you're rebuilding a stock engine, performing routine maintenance, or upgrading your Chevy truck or performance platform, a factory-quality water pump gasket is essential to prevent coolant leaks that can lead to overheating and catastrophic engine damage. This MAHLE ORIGINAL gasket meets OEM specifications and is the genuine replacement part you need for reliable long-term operation.

Manufactured by MAHLE ORIGINAL/CLEVITE under part number K33358, this gasket seals the water pump mounting surface where coolant flow is most critical. MAHLE's precision engineering ensures a perfect fit and reliable compression seal between the pump housing and engine block, maintaining system integrity under pressure and temperature cycling. The gasket's compact design (6.05 x 0.45 x 8.25 inches) and minimal weight (0.065 lbs) integrate seamlessly into your existing cooling system without modification, while the material composition withstands both stock cooling temperatures and the elevated heat loads common in modified or turbocharged applications.

This gasket is ideal for anyone servicing a 2014-model-year or newer Chevrolet 5.3L or 6.2L engine—from daily-driver owners replacing a failed pump to mechanics performing scheduled cooling system overhauls. Installation is straightforward during water pump replacement; simply remove the old gasket, clean the mounting surface thoroughly, and install the new seal with the pump. Compatibility across both displacement platforms means a single SKU covers multiple applications, making inventory management simpler for both professional shops and home builders working on Gen IV/V LS platforms.
