2024 Chevrolet Silverado 1500 A/C Refrigerant & Oil Specifications

Quick answer

• Full system charge: 24.0 oz (680g)
• PAG oil type: PAG 46
• PAG oil amount: 4.1 oz (120mL)

Why R-1234yf matters

The 2024 Chevrolet Silverado 1500, like all new vehicles, uses R-1234yf refrigerant. This is a significant change from the R-134a used in older vehicles. R-1234yf is much more environmentally friendly, but it's also more expensive and requires special equipment to handle. If you're thinking about servicing your A/C system yourself, you'll need to make sure you have the right equipment and that you're properly trained on how to handle R-1234yf. The EPA requires that anyone servicing a mobile A/C system be certified under Section 609 of the Clean Air Act.

Recharge procedure

A full A/C recharge is not a simple DIY project. It's important to have the system evacuated and recharged by a qualified technician who has the right equipment. Topping off the system with a can of refrigerant from an auto parts store is not recommended, as it can lead to overcharging and damage to the A/C system. A proper recharge involves evacuating the system to remove all of the old refrigerant and oil, and then recharging it with the correct amount of new refrigerant and oil by weight.

Common A/C problems for this vehicle

While the 2024 Silverado 1500 is a new vehicle, some common A/C problems that can occur on this generation of trucks include:

• Compressor failures: The A/C compressor is the heart of the system, and it can fail for a variety of reasons. If you hear any strange noises coming from the engine bay when the A/C is on, it's a good idea to have the system checked out by a qualified technician.
• Condenser issues: The condenser is located in front of the radiator, and it's responsible for cooling the refrigerant. It can be damaged by road debris, which can lead to leaks and a loss of cooling.
• Evaporator leaks: The evaporator is located inside the dashboard, and it's responsible for cooling the air that blows into the cabin. If you notice a musty smell coming from the vents, it could be a sign of a leak in the evaporator.

When to call a pro

If you're not comfortable servicing your own A/C system, it's best to leave it to a professional. A qualified technician will have the right equipment and training to do the job safely and correctly. They will also be able to diagnose and repair any problems with the system, so you can be sure that your A/C will be working properly all summer long.
