I need to remove a couple of very stuck sac anodes from the end caps of one of my heat exchangers. I have one stuck anode in each end cap of the heat exchanger.
Will I need to drain the anti-freeze prior to removing the end caps? I actually already started to remove the end cap closest to the after cooler side, and saw some pink drip out which was a big surprise to me, as I would have thought that there should only be sea water in there. I bolted it back up so that I could research it a bit more before proceeding. While I also use a pink winterizing fluid, I would have thought that the pink winterizing fluid would be all flushed thru by now after running the engines for a bit.
If I need to drain the anti-freeze, is that done by removing the plug at the bottom of the goose-neck pipe located under the alternator?
Many thanks,
Dave
