I bought this Haynes book thinking that it would give me the specific information I need to upgrade my cars to R-134a.  I picked it because of the 2000 publication date.  BUT it is clear that they took an old book and just added some new car models to the tables in the back and reissued it.  The coverage of R-134a is totally inadequate.  The varous pressure/temperature tables are unlabeled but presumably apply only to R-12.  The instructions for charging are aimed at R-12 and only use the bulk containers.  Charging with R-134a (which is legal) is addressed by telling you to drive to a commercial shop and paying them to do it.  There is no info on charging from small cans.  There is no comparison of liquid and vapor charging.  Very disappointing.  P.S.  I love the Haynes manual for my Jaguar XJ6 so don't let me scare you off Haynes.
