290,000 MILES???

Anyway, to answer the questions, all of our local auto stores carry, for about
$3.50, a can that contains a die (red) which will help you find your leak.
It's standard practice in air conditioning work to use this stuff.  It is
also available mixed in with freon for about $8 a can or you can buy the
big can from a supply house for about $25.  I know, not cheap, but freon
has pretty good shelf life it you have a spare shelf to store it on.
Also available for about $3.50 a can is a stop-leak formulation which
I have never used but may have try on my daughter's car.  Any one
have any experience with this stuff?
