Hi Again All,
 While there is still some enthusiasm for coolant:
 When is it time to change the coolant?
 Is changing the coolant synonomous with "flushing"?
 I've driven my '85 Westy 16k miles since I bought her last fall.
 In the past 16K miles she used only a pint of 50/50.
 My old mechanic recommended Sierra brand, which I've got.
    Thanks to all for crazy "list" advice & html explanation.
                                     Phaedra
