I plan to drain and replace the antifreeze in my 1981 Delorean. As there is no drain cock on the radiator, please let me know the preferred way to handle this. I have bled the air several times before to remove the air, but have never replaced the antifreeze solution. In addition, if there was a previous Delorean World article (with pictures) on this, I would appreciate the date of the technical article. God, I love this chatline!!!!!!!! I will never sell my Delorean when I have so many friends to reach out to. ------------------------------------------------------------------------ To address comments privately to the moderating team, please address to moderator@xxxx
