Audi EA839 3.0T/2.9T 6 Bolt Water Pump, Thermostat and Shutoff Valve Cooling Maintenance Kit

Complete your Audi EA839 cooling system service with a premium kit featuring the German Performance Solutions Billet Aluminum Thermostat Assembly, Genuine Audi 6 bolt Water Pump, Coolant Pipe and TGK Shutoff Delete. Designed to eliminate multiple common failure points in a single service, this kit replaces the factory plastic components with aluminum upgrades.

Whether you're addressing coolant leaks or performing preventative maintenance, this complete service kit restores cooling system reliability using high-quality OEM and billet aluminum components. The billet thermostat assembly resists cracking, warping, and coolant leaks caused by repeated heat cycles, while the Genuine Audi water pump ensures OEM cooling performance. The included TGK Shutoff Delete removes another failure-prone factory coolant component, reducing complexity and improving long-term dependability.

The EA839's water pump is notorious for failing, allowing coolant to contaminate the vacuum system. This results in a compromised vacuum system which commonly leads to overheating and under boost issues (P0299) due to coolant induced vacuum solenoid failures.  

Please note: Replacing the water pump, thermostat, coolant pipe and shutoff valve is only the first step in repairing a coolant migration failure. Inspect, replace and/or clean all affected vacuum lines and solenoids is required to prevent overheating and under boost issues caused by contaminated solenoids/vacuum lines. Please review our technical page for general guidance on inspecting various solenoid points. 

Additionally: the TGK coolant shutoff valve delete will slightly increase engine warmup time. We measured less than 15 second difference during our testing but results can vary based on ambient temperatures. The test was done on our SQ5s at 70 degrees F.

Why Upgrade?

The factory EA839 cooling system contains several plastic components that commonly fail over time due to repeated heat cycles. Servicing with the GPS billet aluminum thermostat, OEM water pump, and TGK shutoff valve simultaneously minimizes future labor while replacing weak factory components with premium billet aluminum upgrades and a Genuine Audi water pump, providing a more reliable cooling system built for daily driving and high-performance applications.

Additionally the EA839 is plagued with 4 bolt water pump failures. Remove any failure point by upgrading to the newest 6 bolt version that Audi developed to solve this issue.
