Product Details

The Stewart 13103 Stage 1 high-performance water pump is engineered specifically for 1971-1982 Corvette small block Chevy engines. Built on genuine OEM castings machined to exacting tolerances, this pump delivers enhanced cooling performance while maintaining complete compatibility with factory lines and mounting brackets.

Performance Features:

  • Stage 1 internal modifications for improved flow and reliability
  • Precision-machined OEM-grade castings for proper fit
  • 0.75-inch heavy-duty bearing for extended service life
  • 0.75-inch shaft diameter for strength and durability
  • Clockwise rotation (standard SBC configuration)
  • Direct bolt-on installation with stock hardware

Ideal for stock, OEM restoration, and mild performance applications, the Stewart 13103 provides a reliable cooling upgrade without requiring modifications to existing cooling system components. This short-style water pump is the correct replacement for 1971-1982 Corvette small block engines equipped with short water pump configurations.

so far it was good. Got order early and everything was good will definitely will order again.

Good price, Easy to this point. Excellent shipping time,but i received the wrong door skins. I guess a miscommunication trying to resolve it at this time. I think we can work it out.
