2025 Honda CR-V A/C Refrigerant & Oil Capacity

Quick Answer

• Refrigerant Type: R-1234yf
• Full System Charge: 400-450 grams (14.1-15.9 oz) - Always verify with your specific vehicle's underhood label
• PAG Oil Type: PAG 46
• PAG Oil Amount: 130-150 mL (4.4-5.1 fl oz) - Always verify with your specific vehicle's underhood label
• Low-Side Service Port Location: Typically on the larger diameter aluminum line, near the firewall, often on the passenger side.
• High-Side Service Port Location: Typically on the smaller diameter aluminum line, between the condenser and the firewall, often on the driver's side.

Why R-1234yf Matters for Your 2025 Honda CR-V

The 2025 Honda CR-V uses R-1234yf refrigerant, a standard for most new vehicles sold in the United States since 2017. This transition from the older R-134a refrigerant was driven by environmental concerns. R-1234yf has a much lower Global Warming Potential (GWP) than R-134a, making it more eco-friendly.

This change has several implications for vehicle owners and technicians:

• Cost: R-1234yf is significantly more expensive than R-134a, which can impact the cost of A/C repairs or recharges.
• EPA Regulations: The use, handling, and disposal of R-1234yf are strictly regulated by the EPA. Technicians must be 609 certified to work with this refrigerant.
• Specialized Equipment: R-1234yf systems require specific recovery and charging equipment. Attempting to use R-134a equipment or mixing refrigerants can damage the A/C system and is illegal.

Recharge Procedure for Your 2025 Honda CR-V A/C System

Warning: A/C system work should only be performed by a certified technician. Improper handling of refrigerants can cause severe injury, and non-compliance with EPA regulations can result in significant fines. Always wear appropriate personal protective equipment (PPE), including eye protection and gloves.

Here's a high-level overview of a proper A/C recharge, emphasizing critical steps:

1. Evacuate the System: Before adding any new refrigerant, the system must be evacuated using a vacuum pump. This removes any air and moisture, which can cause corrosion and system damage if left inside. Evacuation also helps identify significant leaks.
2. Leak Detection: After evacuation, a vacuum hold test is performed to confirm the system holds a vacuum, indicating no major leaks. If a leak is present, it must be located and repaired before proceeding.
3. Charge by Weight (Crucial!): The most critical aspect of charging an R-1234yf system is to charge it precisely by weight, not by pressure. Overcharging or undercharging, even by a small amount, can severely impact cooling performance and potentially damage the compressor. Refer to the underhood A/C specification label for the exact charge amount. Specialized charging machines are used to ensure accurate measurement.
4. Add PAG Oil (If Necessary): If A/C components were replaced (e.g., compressor, condenser), new PAG 46 oil will need to be added to the system in the specified amount. Always use the correct type and quantity of oil. Too much or too little oil can lead to compressor failure.
5. Performance Test: After charging, the system's performance is tested to ensure proper operation, including vent temperature and system pressures.

Never attempt to charge your A/C system using
