Sounds strange but I did it. My 98 528i was overheating, and I thought the thermostat had gone south, so after dropping in a new one and a water pump as well because at 173k why not.
It over heated again, I bled lots of air out of it and heard a faint hissing but couldn't see any location that would be causing a leak.
So time to pressure test it!
I bought a new radiator cap and a long stem valve to make my own pressure test cap, but the auto parts store also had a real pressure testing cap but nothing to pump it with.
That's when I figured my co2 set up would prove useful. I used my gas line, tank, and regulator to pressurize my system with the new cap and immediately found a hidden leak in my radiator.
I got a new radiator from a friend within the hour and dropped her in and everything was dialed, all while sacrificing some of my co2 tubing.
A lot of people fix cars, and a lot of people make beer. Im the only person I know of to fix their car with brewing gear.
Cheers
