First question do I need to replace the washer second question what size is it as nobody seems to carry it at the automotive parts store so I was going to just get a generic washer. I know the plug itself is a 10 mm size but what size of washer do I need?
I wonder sometimes why this needs saying: dealership parts department had the proper washer, and pick up Toyota ATF WS fluid (4 quarts) while you’re there. there’s a link in my signature on this.
