TGK MotorsportAudi 4.0T Billet Coolant Shut off Switch DeleteFitment: Audi 4.0T Billet

Overview

Upgrade your failure-prone OEM coolant shutoff valve with the TGK Motorsport Audi 4.0T Coolant Shutoff Valve Delete Kit, engineered to ensure consistent coolant flow and eliminate the risk of overheating due to stuck valves. The factory coolant shutoff valve on the Audi 4.0T engine is a vacuum-actuated device located within the cooling circuit that is known to fail in the closed position, preventing coolant from circulating through the engine and causing severe overheating and potentially catastrophic engine damage.

The TGK Motorsport Delete Kit removes this failure-prone component entirely, restoring unimpeded coolant flow throughout the system. By eliminating the shutoff valve, this kit simplifies the cooling circuit and improves long-term reliability — especially in performance or hot-climate driving conditions where consistent coolant flow is essential. Whether you're daily driving or pushing your 4.0T on track, the TGK Motorsport Coolant Shutoff Valve Delete Kit delivers peace of mind and improved thermal management.
