Detailed Description

Dayco DP878 is an engine water pump built for a wide range of GM light-duty and commercial vehicles from 1996 through 1999. Fitment includes Chevrolet C1500, C1500 Suburban, C2500, K1500, K2500, Tahoe, Express 2500, Express 3500, P30, and GMC C1500, K1500, Yukon, Savana 2500, Savana 3500, and related C/K Suburban and 3500-series models. Many listings specify serpentine belt driven systems, and several applications call for a drilled and tapped hub for bolt-on pulley and fan mounting. If you are replacing a worn water pump on a Chevrolet C1500 Suburban or GMC K2500 Suburban, DP878 matches the cataloged configuration for those vehicles.

This part cross-references none listed for the same application.

What It Is Used For

• Replacing a leaking or noisy engine water pump
• Restoring coolant circulation in serpentine belt driven GM engines
• Addressing overheating caused by pump wear or seal failure
• Servicing vehicles with bolt-on pulley and fan hub requirements
• Repairing cooling system issues on Chevrolet and GMC trucks, vans, and SUVs

Installation Notes and Tips

Verify the vehicle’s year, make, model, and cooling system configuration before ordering. Match the notes in the fitment list carefully, especially late, second design, dual thermostat, and drilled and tapped hub applications. Confirm serpentine belt drive layout and pulley/fan mounting style before installation. Always inspect the belt, thermostat, hoses, and coolant condition during water pump replacement.

Quality Assurance

Dayco is a recognized aftermarket brand for engine drive and cooling components. DP878 is cataloged for direct application matching across the listed Chevrolet and GMC vehicles.
