Hello!

 

Is this a shop that is working on a vehicle for the customer or is this your own car?

 

Are you using a AC machine?

Did you just fill it up?

Customer reply replied 8 years ago
yes
Cadillac Mechanic: Amedee, Cadillac Technician replied 8 years ago

Ok.. good!

 

Did you measure it in lbs when you put the freon in the system? Hom many lbs did you put it?

 

Did you evacuate the system after you charged it to see if you recovered the same amount of freon that you put in?
