Water Pump Gasket 97-16 Chevy LS

The Water Pump Gasket 97-16 Chevy LS is a critical engine seal engineered to prevent coolant leakage at the water pump mounting surface on LS-platform engines. Built by MAHLE ORIGINAL/CLEVITE—one of the automotive industry's most trusted gasket manufacturers—this OEM-grade component is essential for any LS engine owner experiencing coolant seepage, performing routine maintenance, or rebuilding their cooling system. Whether you're working on a stock LS1, LS2, LS3, or any variant across the 1997–2016 model range, this gasket ensures a reliable, leak-free seal that protects your engine from overheating and coolant loss.

This water pump gasket is precision-manufactured from advanced elastomer and composite materials that withstand the thermal cycling and pressure cycles inherent to modern LS engines. The gasket's engineered thickness and surface profile create a uniform seal across the pump flange, minimizing the risk of micro-leaks that can develop under boost or sustained high-RPM operation. Unlike inferior aftermarket alternatives, MAHLE's formulation resists coolant degradation and maintains integrity even when exposed to extended high-temperature conditions, making it ideal for street machines, track cars, and modified builds where cooling system reliability is non-negotiable.

Mechanics and engine builders choose this OEM-equivalent gasket for in-frame reseal jobs, full engine rebuilds, and preventive maintenance on higher-mileage LS powerplants. Installation is straightforward—simply remove the water pump, clean both sealing surfaces thoroughly to bare metal, and install the new gasket dry (no sealant needed on this design) before torquing the pump bolts to factory spec. Compatible across all LS generations from the original LS1 (1997) through the LS3 and late-model variants (2016), this gasket is a no-compromise choice for anyone unwilling to compromise cooling system durability.
