TGK-0304-08
Eliminate the elusive cold-temperature coolant leak on your Audi 4.0T with the TGK Motorsport Front Thermostat Billet Piping Kit — engineered to replace the factory plastic coolant elbow with a precision-machined 6061 aluminum solution featuring a dual-gasket design for maximum sealing and long-term reliability.
The factory Audi 4.0T cooling system utilizes a plastic coolant elbow at the front thermostat housing that is a common failure point. This component relies on a single O-ring to seal against the thermostat housing, which over time becomes prone to hardening, deformation, and leakage — especially under cold start conditions. These leaks are often difficult to trace, leading to recurring coolant loss without an obvious source.
