Coolant Leak S90-V90

I would try 2 things:

Shampoo engine to make sure no deposits of coolant are anywhere on rad/hoses, engine etc. Then add the coolant die into coolant mix,drive around for a while and check with black light to see where its leaking..

The second thing is to pressurize the system and see if its holding pressure. I was thinking of buying another rad overflow cap. Tapping in a thread for an air line fitting with an on/off valve. Then using my compressor pump it up to 20psi, and shut the valve off and see if it holds pressure. Maybe spray soap and water at suspect areas to see where its leaking.

Good luck!!
