2022 Ram 2500: A/C Refrigerant & Oil

Quick answer:

• Refrigerant type: R-1234yf
• Full system charge: 24 oz (680 g)
• PAG oil type: PAG 46
• PAG oil amount: 6.8 oz (200 ml)

Why R-1234yf matters

The 2022 Ram 2500 uses R-1234yf refrigerant, which has a much lower global warming potential than the R-134a used in older vehicles. This is good for the environment, but it also means that you can't just top off your system with a can of refrigerant from the auto parts store. R-1234yf is more expensive than R-134a, and it requires special equipment to handle. You'll need to take your truck to a qualified shop to have the A/C system serviced.

Recharge procedure

The first step in recharging your A/C system is to evacuate the old refrigerant. This is done with a special machine that removes the refrigerant and stores it in a tank. Once the system is empty, it's time to add the new refrigerant. The amount of refrigerant that you add is critical, so it's important to use a scale to measure it accurately. The system is then charged to the correct pressure.

Common A/C problems for this vehicle

One of the most common A/C problems for the 2022 Ram 2500 is a leak in the evaporator core. The evaporator core is located inside the dashboard, so it's a difficult and expensive repair. Other common problems include compressor failures and condenser leaks.

When to call a pro

If you're not comfortable working on your own A/C system, it's best to take it to a qualified shop. A/C work can be dangerous, and it's important to have it done correctly. A professional technician will have the special tools and equipment needed to do the job right.
