Z4 M no mess anti-freeze block drain
Installing gauge senders for the two gauges I'm adding. Water temperature sender goes in the stock anti-freeze drain plug.
Typically a major mess draining the anti-freeze.
If you have time (my car is on stands for the next couple of months) you can drain without a mess.
Take four to six sheets of Bounty paper towels and roll them up. Position them just under the block drain plug heading down.
Unscrew the plug some. The fluid gets sucked in by the Bounty. Gravity gets it to the bottom of the Bounty into the bucket.
Alan Alfano mentioned adding tin foil under the Bounty. Not necessary. The Bounty sucks up all of the fluid with no residue.
Hard to believe but it works.
Radiator drain is not a problem since the drain plug is straight down.
Drained ~7 quarts total. Don't know the Z4 M capacity. Z4 3.0 is 8 quarts with manual transmission.
