2022 Jeep Wrangler A/C Refrigerant and Oil Specifications

Quick answer

• Refrigerant type: R-1234yf
• Full system charge: 19.0 oz (538 g)
• PAG oil type: PAG 46
• PAG oil amount: 4.5 oz (133 mL)
• Low-side service port location: Near the firewall on the passenger side
• High-side service port location: Near the radiator on the driver side

Why R-1234yf matters

As of 2018, all Jeep Wranglers use R-1234yf refrigerant. This is a newer, more environmentally friendly refrigerant than the R-134a used in older vehicles. However, it is also more expensive and requires special equipment to handle. You cannot use an R-134a recovery machine with an R-1234yf system, and vice versa. This is because the two refrigerants are not compatible and can damage your A/C system. If you are not sure which refrigerant your Wrangler uses, check the sticker under the hood.

Recharge procedure

Recharging your Wrangler's A/C system is not as simple as just adding more refrigerant. The system must be evacuated of all old refrigerant and oil before it can be recharged. This is to ensure that the system is not contaminated with moisture or air, which can damage the compressor. The system must then be recharged with the exact amount of refrigerant and oil specified by the manufacturer. Do not try to charge the system by pressure, as this can lead to overcharging and damage to the A/C system.

Common A/C problems for this vehicle

One of the most common A/C problems for the Jeep Wrangler is a leak in the evaporator core. This is a difficult and expensive repair, as the entire dashboard must be removed to access the evaporator. Other common problems include compressor failures and condenser leaks.

When to call a pro

If you are not comfortable working on your Wrangler's A/C system, it is best to take it to a qualified technician. A/C work can be dangerous, and it is important to have the proper training and equipment. Additionally, all technicians who work on A/C systems must be certified by the EPA. This is to ensure that they are properly trained to handle refrigerants and protect the environment.
