Water Pump Plate Pontiac V8

The Water Pump Plate Pontiac V8 from ALLSTAR PERFORMANCE is a precision-engineered back plate designed for builders and restorers working with classic Pontiac V8 engines. This steel component sits between your water pump and engine block, serving as a critical seal point that prevents coolant leakage and maintains system integrity under sustained operating temperatures. Whether you're rebuilding a 400, 428, or 455 Pontiac engine, this plate ensures proper flow management and protects against common failure points that plague aging cooling systems.

Manufactured from solid steel in natural finish, the Water Pump Plate Pontiac V8 resists corrosion and thermal stress better than aluminum alternatives, making it ideal for high-output or street-driven applications where cooling system reliability matters. The plate's compact 8.05 x 1 x 13.35 inch footprint allows direct bolt-on installation without modification, and its 0.635 lb weight ensures minimal impact on engine bay dynamics. The natural finish accepts paint or powder coating if you prefer a finished appearance, while the as-delivered state offers straightforward installation for those prioritizing function over aesthetics.

Enthusiasts and professional engine shops rely on this plate when replacing worn pumps, upgrading cooling capacity, or performing full engine restorations on Pontiac V8s. The single-piece design eliminates multi-part assembly headaches and delivers consistent clamping pressure across the water pump gasket surface. Installation takes minutes with standard bolts, making it an essential component for anyone serious about cooling system longevity in classic American iron.
