The Water pump Gasket LS 1997-Up Metal/Rubber from Straub Technologies Inc. is a precision-engineered replacement component designed for General Motors LS-series engines spanning 1997 to current model years. This gasket forms a critical seal between the water pump housing and engine block, preventing coolant leakage that can lead to overheating, corrosion, and catastrophic engine failure. Whether you're performing routine maintenance, rebuilding an LS engine, or addressing a cooling system leak, this OEM-quality gasket ensures reliable long-term performance.
Constructed with a combination of aluminum and rubber materials, the Water pump Gasket LS 1997-Up Metal/Rubber provides superior sealing properties across a wide temperature and pressure range typical of modern LS powerplants. The aluminum core delivers structural rigidity and excellent thermal conductivity, while the rubber facing creates a compliant, leak-resistant seal against both the water pump and engine block surfaces. This dual-material design minimizes gasket creep, reduces the risk of coolant bypass, and extends service intervals compared to single-material alternatives. The compact dimensions (4.05 x 0.25 x 6 inches) and lightweight profile (0.05 lbs) make installation straightforward without requiring special tools or modifications.
LS engine builders, professional technicians, and enthusiasts rely on this gasket for both stock restorations and high-performance builds. It is directly compatible with all LS-family engines including LS1, LS2, LS3, LS7, and LS9 variants across trucks, SUVs, and performance vehicles. Installation requires removal of the water pump from the engine block; proper surface cleaning and a fresh gasket application ensure optimal sealing. This single-unit gasket (sold individually) should be replaced during any water pump service to prevent premature cooling system failure and maintain engine reliability over thousands of miles.
