Just wanted to say thank you. I just finished a 24K service yesterday. It was a little late as Elizabeth has a little better than 27 K on her but all is well. I completed all required items plus the antifreeze change. I did find most of the valves tight so I bought one of the new Clymer manuals and followed the suggestions on this site and all is good. Again, thanks for all of the input that has been posted.
