I went to bleed the cooling system yesterday in the m30 and the thermostat was stuck and radiator was staying cool. New thermostat in today, it opens, and radiator warms up. I just cant seem to keep coolant in the overflow tank, it just wants to overflow.. When I crack the bleeder i get air for a long time then a little coolant out, then air, then a little coolant, but coolant continues to want to overflow out of the tank like crazy... Is this normal? Should I just continue the process?

Problem solved. Took a six mile drive with many stops and over heating to get all the air out. Now i just seem to be losing power like a bad alternator, but the battery is still reading 11 volts, but the car will not run on that... -
11 volts with engine running means the alternator or something with the charging system is toast.
11 volts with the car off is a dying battery.Comment

Before you crack open the bleeder, I find it helpful to bring up the revs and hold them up until you close the bleeder.
And the car should read 14 or so volts when running IIRCComment
