Is there a web site, or book that will tell me the specs for all vehicles.

I have Toyotas, Hondas, and Mazda vehicles.

The Mastercool book that came with my set covers some but not all.

yes, there are many-- look in the technical section.

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

I looked under Procedures, Tips, and FAQ, and got Temp Pressure chart, and System capacities.

I couldn't find one on what the gauges should read for a healthy system.
