Today I filled my cooling system again after replacing the waterpump yesterday. Went much better this time having probably most of the coolant still in the radiators etc. (previous time, everything was empty). I think I got about as much back in as ran out yesterday. Might have spilled a bit, but should be close. I did a combination of vacuum for getting initial air out (still quite effective) and pressure (pushing the air to places where it can escape). Now when I pressurize to 1 bar, the fluid gets pushed down to about half the reservoir, so not that much air left anymore.

Put the longer belt on (I suspect the short-ish belt might have made the waterpump die) which does fit better. Still have a bit left on the tensioner. So updated belt length for engines with AC (or at least the compressor in place as I have now), but without PS pump is 6PK2080. I guess a 2100 might still work, but this one works well, better than the 6PK2065 I had on it before.
