Detailed Description

WP805 is engineered for drivers and technicians replacing a worn or leaking water pump on Audi and Volkswagen turbo and non-turbo cooling system applications. The pump is designed to maintain proper coolant movement through the engine, helping the system regulate operating temperature under daily driving and sustained load. DJ Rock WP805 is a direct-fit cooling component for models such as the Audi A4, A5 Quattro, Q5, and Volkswagen GTI, Jetta, Passat, and Tiguan, with fitment notes calling out metal impeller applications where specified.

What It Helps Address

• Coolant circulation loss from a worn pump
• Engine overheating caused by reduced coolant flow
• Coolant seepage from a failing shaft seal
• Noisy operation from worn bearings
• Temperature instability during normal driving

Installation Notes and Tips

Verify engine code, model year, and the metal-impeller note before installation. Replace the pump only after confirming the cooling system is clean and free of contamination, and inspect related hoses, thermostat components, and seals during service. Follow the vehicle service procedure for coolant refill and bleeding to remove trapped air.

Quality Assurance

DJ Rock WP805 is manufactured to meet or exceed OEM quality standards and uses premium materials selected for durability in cooling system service. The design emphasizes precise fitment, reliable sealing, and consistent coolant flow for the listed Audi and Volkswagen applications.
