What is the standard amount of refrigerant to add to a car?

[LeSamantha]

Generally, adding 3 to 4 cans is sufficient, depending on the compressor's displacement and the length of the air conditioning pipes. Here are the details: 1. Standard range: Typically, small cars require between 450g to 600g, while some SUVs may need between 600g to 1000g. It's essential to monitor the gauge when adding refrigerant; adding more won't help if it's not cooling. Usually, about three cans will provide adequate cooling, but the decision to add more should be based on pressure readings. 2. Introduction to refrigerant: Refrigerant, commonly known as 'snow seed' in some southern regions, is the working substance that continuously circulates within the refrigeration system and achieves cooling through its own state changes. The refrigerant absorbs heat from the cooled medium (such as water or air) and vaporizes in the evaporator, then releases heat to the surrounding air or water and condenses in the condenser.
