As much as the manufacturer specifies. Each vehicle has its own capacity, and two cars being "small" doesn't mean it'll be the same for both of them.
Usually 2-3 lbs.
Open the hood on your car. There will be a tube with a label on it that signifies it is for refrigerant. Put the hose on the coolant can to the connector on the tank and hold the button on the can down in small bursts.
There are both light and heavy duty car lifts that work for small and large vehicles. Car lifts can hold up to 6,000 pounds, and a four post lift will hold more weight than a two post lift.
a car can hold up to 3 gallons.
There should be a sticker under the hood which tells which refrigerant is used and how much for that particular system.
Well I don't know much about that car but it could prolly hold a small 6 cylindar, prolly not much higher.
A coal car can hold between 234,800 to 242,300 pounds.
it hold 34 liters
Too much or too little refrigerant.
Let it drain out. It will overfill, just let it drain.
It varies by car and the information should be able to be found on a sticker under the hood.
Yes you can have too much refrigerant in your A/C system and it will damage the system. The only way to know how much is in the system is to measure it by using a gauge.
