The 2018 Honda Fit holds about 21 ounces (roughly 0.62 kilograms) of R-134a refrigerant when charged.
Exact amounts can vary slightly by trim and service history. Typical charging guidance lists roughly 19–23 ounces of refrigerant for the 2018 Fit, with the compressor oil charge treated separately according to the service manual. For the most accurate figure, consult the under-hood A/C label and the official service documentation.
Refrigerant type and system capacity
The Fit's air-conditioning system uses R-134a refrigerant. This is standard for many non-turbo Hondas of this era and aligns with widely used service equipment.
Key capacity details
Below is a concise breakdown of the numbers technicians reference when recharging the system.
- Refrigerant type: R-134a
- Refrigerant capacity (refrigerant only): about 21 oz (0.62 kg)
- Typical service range: about 19–23 oz to accommodate production and service variations
- Oil charge: separate from refrigerant; the amount is specified in the service manual or on the vehicle’s A/C label
Concluding: Always verify with the official service documentation or the under-hood A/C label on your vehicle when performing a recharge.
Practical steps for verifying the charge
When preparing to recharge or evacuate and recharge the system, technicians use manifold gauges, a recovery machine, and a scale. The label on the engine bay typically lists the correct refrigerant type and capacity, and the service manual provides the precise oil charge and procedure for the 2018 Fit.
What to avoid
Avoid overfilling, which can cause high pressure, compressor strain, and poor cooling. Always follow the specified target pressures and procedures to ensure proper operation and reliability.
Summary
The 2018 Honda Fit uses R-134a refrigerant and typically holds about 19–23 oz (roughly 540–650 g) of refrigerant, with the standard average around 21 oz. The oil charge is separate and must be referenced from the service manual or the engine- bay label. For precise numbers, rely on the official Honda documentation or your vehicle’s A/C label to ensure a correct recharge and optimal performance.
