S4 Coolant Leak Tool

I noticed a small coolant leak on my car recently. It wasn’t clear where it was coming from, only that it was somewhere in the front and only occurred after running for some time. To help troubleshoot this I created a 3d printed adapter that interfaced a tire schrader valve to the coolant tank, sealed with an O-ring. An F clamp held this adapter in place and I pressurized the coolant system to a few PSI. This lead to the discovery of a bad O-ring on one of the coolant crossover pipes at the supercharger, which was easily fixed.
