A 2005 Peterbilt 379 typically requires about 30 ounces (approximately 2.5 pounds) of R134a refrigerant for the air conditioning system. The high-pressure side should generally be between 200-250 psi, while the low-pressure side should be around 25-45 psi, depending on ambient temperatures. Always refer to the vehicle's service manual for the most accurate specifications.
How much freon does a 2010 Peterbilt
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.
Should be 3 lbs., 12 ounces for a factory original (not reconfigured) day cab and 4 lbs. for a sleeper.
Sleeper berth ProStars typically require exactly three pounds of refrigerant.
I believe it's 3.5 lbs, but I'd recommend you call a Peterbilt dealership to verify this.
what is the freon capacity of a 379 pete with sleerer
On the older cars its best to start out with 3 pounds of freon and work from there reading both the high and low pressures on the gauges assuming you are using R-12 freon and the a/c system is factory........
8 oz of oil in a dry system 4lbs of freon with a sleeper
about 3.5 to 4 lbs of r12, with a sleeper. less without a sleeper, or with r134a
3.50 lbs. Works well.
The 1998 Peterbilt 379 typically requires about 20 ounces (or 1.25 pounds) of R-134a refrigerant for its air conditioning system. However, it's always best to consult the vehicle's service manual or check with a qualified technician for the precise amount and specifications, as variations can occur based on the specific configuration or modifications of the truck.
