How do you add feon to the ac on a peterbilt truck?

Answer 1

TO ADD FREON TO A PETERBILT YOU MUST FIRST GET SOME TRAINING ON THE A/C SYSTEM.THEN YOU HOOK PU YOUR A/C GAUGES (134A) SET,BLUE TO THE LOW SIDE AND RED TO THE HIGH SIDE.NOW TURN ON THE TRUCK , MAKE SURE THE A/C IS ON THEN GO BACK TO YOUR GAUGES AND OPEN THE VALVES .BUT ONLY AT THE FITTINGS NOT ON THE MANIFOLD.NOW YOU SHOULD HAVE A READING ON YOUR GAUGES.

A GOOD READING IS ABOUT 35 P.S.I ON THE LOW SIDE AND NOT TO EXCEED 300 P.S.I ON THE HIGH SIDE, DON'T OVER CHARGE IT OR DAMAGE CAN BE DONE TO THE A/C SYSTEM.
