Dayco DP862 Engine Water Pump Auto/Light Truck

The Dayco DP862 is a direct-fit replacement engine water pump designed for auto and light truck applications. Built to meet or exceed OEM specifications, this water pump delivers reliable coolant circulation to keep your engine operating at the proper temperature.

Dayco engineers each water pump using 100% new cast iron construction — no remanufactured cores — ensuring consistent quality and long-term durability. The one-piece housing eliminates weak points common in multi-piece designs, while the upgraded impeller promotes improved coolant flow and overall cooling system efficiency.

Key Features:

• Durable one-piece cast iron construction — no welds, no remanufactured cores
• Upgraded impeller design for enhanced coolant flow and performance
• Case-hardened roller bearings engineered to flex without fracturing under load
• Superior gaskets and unitized seals to prevent coolant leaks
• V-belt driven with standard impeller rotation
• 5 mounting holes, 8 impeller vanes, 4 hub holes
• Meets rigorous TS16949 quality standards
• Backed by an industry-leading 125,000-mile warranty (upon online registration)

The Dayco DP862 is sold individually as the main pump component. Pulley, fan clutch, back housing, thermostat, and mounting hardware are not included. For maximum cooling system protection, Dayco recommends flushing the cooling system and installing fresh OEM-spec coolant at the time of installation.
