Detailed Product Description

This engine water pump features a cast iron housing that withstands high temperatures and mechanical stress, making it suitable for heavy-duty use in vehicles like the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade.

The pump is driven by an accessory belt, aligning with the original equipment design. Included with the water pump are two gaskets to ensure a secure and leak-free installation.

Ensure the engine is cool before beginning installation. Use the included gaskets to prevent coolant leaks and verify that the accessory belt is properly tensioned after installation.
