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.

There are a multitude of possibilities here. You need to have a system performance test done to help narrow the cause down.
You put it in on the low side in the line about center of the engine.
We need to know if it's a day cab or a sleeper berth truck with dual AC unis in order to answer this question. For the latter, it should be 3.5 lbs (56 ounces).
You can add air conditioning refrigerant to your 2000 F1 50 pickup truck air conditioning system through the low pressure port. The low pressure port will be on the top of the air conditioning compressor.
They have automatic tensioners. If the belt needs adjustment, either you have a bad tensioner or a worn belt.
The truck needs a tune up.
Usually not.
yes
turn on the ac and open the door or window
Many home AC units are sealed, and there is no way for a homeowner to add refrigerant.
Well, it's only Freon if it was manufactured by DuPont and sold under that name - Freon is a trademark of A.I. DuPont Corp. and applied to a line of CFC and HFC refrigerants manufactured by them.But, on to what's important... a 2007 Peterbilt WHAT??? You have to understand that Peterbilt manufactured (and continues to manufacture) trucks from Class 5 to Class 8, and refrigerant capacities will vary between, say, a Peterbilt 330 day cab and a Peterbilt 379 with a sleeper berth and dual AC systems.
