What kind of freon does a 2017 Chevy Silverado 5.3 take?
The 2017 Chevy Silverado 5.3 uses refrigerant R-134a (commonly known as Freon) in its air conditioning system, not the newer R-1234yf. It also requires PAG oil for the lubricant. The typical total charge is around two pounds (about 32 ounces) of refrigerant, though the exact amount can vary by vehicle configuration and service history. For precise specifications, consult the owner’s manual or a qualified automotive technician.
Refrigerant type and lubrication
Oil specification and system capacity
Understanding the refrigerant and lubrication helps ensure proper service and long-term performance of the A/C system.
- Refrigerant type: R-134a (not R-1234yf)
- Lubricant: PAG oil, commonly PAG-46 used with R-134a systems
- Typical system charge: roughly 28–34 oz of R-134a (approx. 0.8–1.0 kg), with the exact amount depending on what components are present and whether the system has been serviced previously
Always verify the exact oil grade and refrigerant quantity for your specific Silverado model using GM service data or the owner’s manual, and have a qualified technician perform any charging or component replacement.
Charging and service guidance
Best practices for servicing the A/C system
When servicing the Silverado’s air conditioning, follow established procedures to avoid damaging the compressor or reducing cooling performance.
- Recover and evacuate the system to remove existing refrigerant and moisture with approved equipment
- Inspect and, if necessary, replace the receiver-drier/accumulator and the expansion device if the system has been opened
- Recharge with the correct refrigerant (R-134a) and the appropriate amount of PAG oil as specified for your vehicle
- Test the system across a range of temperatures and monitor low- and high-side pressures to ensure proper operation and detect leaks
Note: A/C charging and leak testing should be performed by trained technicians. Using the wrong refrigerant or incorrect oil quantities can cause compressor damage and reduced cooling efficiency.
Summary
In summary, the 2017 Chevy Silverado 5.3 takes R-134a refrigerant with PAG oil, with an overall system charge typically around two pounds (approximately 32 oz), though exact figures vary by vehicle and service history. For precise specifications, consult GM’s service data or a dealership technician, especially before attempting any recharge or component replacement.
