How many grams of refrigerant is appropriate to add to a Nissan Teana?

[DeLuke]

It is appropriate to add 600 grams of refrigerant to a Nissan Teana. Lack of refrigerant: When the air conditioner lacks refrigerant, frosting will appear on the low-pressure liquid supply pipe, which is a typical fault phenomenon. Partial blockage: The blockage point is generally more common at the filter outlet or capillary inlet. Due to the partial blockage in the system, a throttling effect occurs, causing the pressure after throttling to be lower than the normal operating value of the air conditioner, resulting in frosting on the liquid supply pipe. Normal phenomenon: When the air conditioner starts running, the condensation temperature and pressure are relatively low, and the capillary liquid supply is lower than the normal value, causing the evaporation pressure to decrease accordingly. Therefore, frosting occurs on the low-pressure liquid supply pipe. Generally, frosting starts when the compressor runs, and the entire frosting and melting process ends within 5 minutes, after which the air conditioner enters normal operation.
