A simple adapter for pressurizing the cooling system to detect leaks for Volvo P2 platform (V70, S60, XC90, S80). 

A standard automotive valve (Schrader) is used for connection. I recommend using sealing O-rings for better tightness (see photo). Tested up to approximately 0.5 bar.

I recommend using a more durable material for printing (PETG, ASA, etc.), more perimeters, and a high infill density for greater strength.

The black print in the video is made from ASA; it worked great and sealed perfectly. The orange print in the photos is a slightly modified test version with easier installation on the expansion tank printed from PLA with only 2 perimeters (just only for fit testing).
