2017 Chevrolet Malibu: A/C Refrigerant & Oil

Quick answer: 2017 Chevrolet Malibu A/C specs

• Refrigerant type: R-1234yf
• Full system charge: 17.6 oz (500g)
• PAG oil type: PAG 46
• PAG oil amount: 4.4 oz (130mL)
• Low-side service port location: Near the firewall, on the passenger side
• High-side service port location: On the driver's side, near the radiator

Why R-1234yf matters

Starting in 2014, General Motors began transitioning its vehicle fleet from R-134a to the more environmentally friendly R-1234yf refrigerant. The 2017 Chevrolet Malibu uses R-1234yf, which has a much lower global warming potential (GWP) than its predecessor. However, this change has several implications for both DIY and professional mechanics:

• Cost: R-1234yf is significantly more expensive than R-134a. This is due to both the chemical's cost and the specialized equipment needed to handle it.
• EPA regulations: While anyone can still purchase R-134a, R-1234yf is more tightly controlled and often requires EPA 609 certification to purchase. Furthermore, it is illegal to vent R-1234yf into the atmosphere, so a recovery machine is required.
• Recovery machine requirements: Servicing an R-1234yf system requires a dedicated recovery machine. Cross-contamination with R-134a can cause system damage and is illegal.

Recharge procedure

A proper A/C recharge is not a simple top-off. To ensure optimal performance and longevity, the system must be evacuated and recharged by weight. Here's a high-level overview of the process:

1. Recover: Using an R-1234yf-specific recovery machine, remove all refrigerant from the system.
2. Evacuate: Pull a deep vacuum on the system for at least 30 minutes. This removes any moisture, which can freeze and cause blockages.
3. Recharge: Using a digital scale, add the precise amount of R-1234yf refrigerant specified by the manufacturer (17.6 oz/500g for the 2017 Malibu).
4. Add oil: If any components were replaced, add the appropriate amount of PAG 46 oil.

Do not use pressure gauges to determine the refrigerant charge. This is an inaccurate method that can lead to over or undercharging, both of which can damage the A/C system.

Common A/C problems for this vehicle

The 2017 Chevrolet Malibu is generally a reliable vehicle, but like any car, it can have A/C problems. Here are a few common issues to look out for:

• Compressor failures: The A/C compressor is the heart of the system, and it can fail for a variety of reasons, including lack of lubrication or internal wear.
• Condenser issues: The condenser is located at the front of the vehicle and is susceptible to damage from road debris. A clogged or damaged condenser will not be able to properly cool the refrigerant, resulting in poor A/C performance.
• Evaporator leaks: The evaporator is located inside the dashboard and is responsible for cooling the air that blows into the cabin. A leak in the evaporator can be difficult to diagnose and often requires the removal of the entire dashboard to replace.

When to call a pro

While some basic car maintenance can be done at home, A/C system repair is best left to the professionals. The specialized equipment and knowledge required to safely and effectively service an R-1234yf system make it a job for a certified technician.

Disclaimer: A/C systems are under high pressure and can be dangerous to work on without proper training and equipment. Always wear safety glasses and gloves when working on or around an A/C system. EPA 609 certification is required to legally service A/C systems.
