I plan to drain, flush and refill the antifreeze in both engines this fall. I've been Googling to learn how to do this, and not finding any great results.
Is there an article or a link here someone can refer me to?
I can copy/paste the service manual but you drain, fill with plain water and run up to temp, drain, fill back up with AF. I’d usually needs a topoff as well once air escapes
Draining is messy, epsoecially on the port side. You pull the plug from the J pipe at the engines lowest point. I’ll be putting in valves next time so I can hook a pump up
