2015 Jeep Cherokee A/C Refrigerant & Oil Capacity

Quick Answer

• Refrigerant Type: R-1234yf
• Full System Charge: 16.96 oz (481 grams)
• PAG Oil Type: PAG 46
• PAG Oil Amount: 4.7 fl oz (140 mL)
• Low-Side Service Port Location: On the accumulator/drier, typically near the firewall on the passenger side.
• High-Side Service Port Location: On the liquid line, often near the condenser or along the discharge line from the compressor.

Why R-1234yf Matters

The 2015 Jeep Cherokee uses R-1234yf refrigerant, a significant change from the older R-134a. This transition began around 2014 for many vehicles due to environmental regulations aimed at reducing global warming potential. R-1234yf has a much lower impact on the atmosphere than R-134a, making it the environmentally preferred choice.

However, this comes with a few implications:

• Cost: R-1234yf is generally more expensive than R-134a, which can increase the cost of A/C repairs or recharges.
• EPA Regulations: Specific EPA Section 609 certification is required for technicians to purchase and handle R-1234yf, just as it is for R-134a. This helps ensure proper handling and reduces refrigerant venting into the atmosphere.
• Specialized Equipment: R-1234yf systems require dedicated recovery and recharging equipment designed specifically for this refrigerant. Cross-contamination between R-134a and R-1234yf systems must be avoided, as it can damage both the vehicle's A/C system and the service equipment.

Recharge Procedure Cautions

Recharging an R-1234yf A/C system is not as simple as adding a can of refrigerant. It requires precision and proper equipment. Never use stop-leak products, and do not attempt to recharge your system with R-134a. Mixing refrigerants can cause severe damage to your A/C system and violate environmental regulations.

Here's a high-level overview of the correct procedure, which should ideally be performed by a certified professional:

1. System Evacuation: A vacuum pump is used to remove all air and moisture from the A/C system. This is a critical step, as moisture can freeze and create acids that corrode internal components.
2. Leak Detection: Before recharging, the system should be checked for leaks using appropriate R-1234yf leak detection methods. Charging a leaky system is wasteful and harmful to the environment.
3. Proper Charge by Weight: The correct amount of refrigerant is crucial. The 2015 Jeep Cherokee requires precisely 16.96 ounces (481 grams) of R-1234yf. This is measured by weight with a specialized charging machine, not by pressure. Overcharging or undercharging can lead to poor cooling performance and potential compressor damage.
4. PAG Oil Addition: If components were replaced or the system was opened for an extended period, the correct type (PAG 46) and amount (4.7 fl oz / 140 mL) of PAG oil must be added back into the system to lubricate the compressor.

Common A/C Problems for the 2015 Jeep Cherokee

While the 2015 Jeep Cherokee generally has a reliable A/C system, some common issues can arise:

• Compressor Failures: The A/C compressor is the heart of the system. Failures can manifest as a lack of cold air, loud noises when the A/C is on, or a burning smell. These failures can sometimes be linked to improper refrigerant levels or contaminated systems.
• Condenser Issues: The condenser, usually located in front of the radiator, dissipates heat. Damage from road debris (rocks, etc.) can lead to leaks. A clogged or damaged condenser can also reduce cooling efficiency.
• Evaporator Leaks: The evaporator core, located inside the dashboard, can develop leaks. Symptoms include a musty odor from the vents, unexplained refrigerant loss, or water on the passenger floorboard.
• Blend Door Actuator Failures: While not a refrigerant-specific issue, blend door actuators control the airflow and temperature. A failing actuator can cause inconsistent temperature control or air blowing only out of certain vents.

When to Call a Pro

Working with automotive air conditioning systems involves high pressures and specialized refrigerants, which can be dangerous if not handled correctly. Improper procedures can lead to personal injury, environmental damage, and costly repairs.

Always consult a professional A/C technician who is EPA 609 certified, especially when:

• Your A/C system isn't blowing cold air.
• You notice any unusual noises or odors from your A/C.
• You suspect a leak.
• You need to add or remove refrigerant.

Safety Disclaimer: Automotive A/C systems contain refrigerants under high pressure. Refrigerant can cause frostbite or blindness if it comes into contact with skin or eyes. Always wear appropriate personal protective equipment, including safety glasses and gloves, if inspecting components. It is illegal to intentionally vent refrigerants into the atmosphere. Only EPA Section 609 certified technicians should perform A/C service involving refrigerant handling.
