Quick Answer: 2017 Metris A/C Specs
- Refrigerant Type: R-1234yf
- Full System Charge: 25.4 oz (720g)

- Low-Side Port: Near the driver-side firewall
- High-Side Port: Front of the condenser, passenger side
Why R-1234yf Matters
The 2017 Metris uses R-1234yf, a refrigerant with a lower global warming potential (GWP) than its predecessor, R-134a. While better for the environment, R-1234yf is more expensive and requires specialized A/C service equipment. Do not attempt to substitute R-134a or use off-the-shelf recharge kits, as this can damage your system and is illegal.
Recharge Procedure
A proper A/C service involves more than just adding refrigerant. The system must be fully evacuated to remove air and moisture, then recharged with the precise weight of refrigerant. This requires a dedicated R-1234yf machine and is not a DIY job.
Common A/C Problems
- Compressor Failure: The Metris's A/C compressor can be prone to clutch failure. Symptoms include a lack of cold air and a noisy compressor.
- Condenser Leaks: Road debris can damage the condenser, leading to refrigerant leaks. Look for oily residue on the condenser fins.
- Evaporator Leaks: A musty smell from the vents can indicate a leaking evaporator core, a costly repair.
When to Call a Pro
Due to the complexity and legal requirements of working with R-1234yf, A/C service on your 2017 Metris is best left to a certified professional. They have the right tools and expertise to diagnose and repair your A/C system safely and effectively.
Disclaimer: The U.S. EPA requires anyone servicing motor vehicle A/C systems to be certified under Section 609 of the Clean Air Act.
