Re: 2000 Daewoo Luganza
The kit should come with instructions. I recommend taking it to a lisenced repair facility. You may have other issues than low low freon. Besides, the proper way to do it is to have a vacuum pulled on the system to remove any air. Any air in the system will prevent the ac from working at peak performence.

The backyard mechanic answer is this: Reconnect all hoses. Use a recharge kit with the engine off and just put some pressure back into the system, keeping the Refrigerant can upright. Check for any leaks with soapy water by the repaired connection.
If no leaks, you know have to purge the system. The correct way is to evacuate the air with a vacuum pump. If you don't have that, the alternative is to remove the kit from the charge port. Carefully press in the small pin in the center of the port to open the valve and release all the gas you just charged in. Refill again like you did the first time, DONT run the engine, just let the refrigerant can pressurize the system again. The bleed it off again. Repeat this several times.
Each time you do that, you dilute the air that may have gotten into the system, and increase the percentage of refrigerant vapor. After about four or five times doing this, most of the air and moisture should be removed. Refill the system as described on your refill kit and you should be back in business.
Note: don't this with R-12 gas, it is an environmental hazard, R134a is not.
The best thing i can tell you is to take it into a shop. You can add freon to a system but you need to know what kind your vehicle needs. If it takes the new current freon your in luck you can buy a recharge kit at any local parts store. If not you have a few options. You can get a conversion kit to change the system over to the new freon or you can try to find a shop that can recharge it with the older freon for your vehicle. Since its an 01 it should be the new freon but i cant be sure. There is a fitting with a cap on it on you AC Lines. should be 2 a red cap and a green cap. You remove the green cap and with the engine running attach a recharger bottle from the store and refill the system. Note the freon recharge kit will come with some instructions to always read them first. hope that helps good luck.
Your recharge hose/kit will only fit one side - check the fittings, and to answer your other question can should be upright so you fill with gas. Turning it upside down you have the chance of over-filling and blowing seals when freon expands.
Check to see if your AC compressor is turning, If it is then you need to refil system with freon equivalent thru the low pressure port. The kit you get will only let you put it on the low presure line. You can pick the lit up at any auto supply store. just folow the instructions on the kit. If the compressor clutch is not engaging check AC relay
Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle.
Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power.
Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High
Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can.
Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood.
Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
You find the AC low pressure at the top of the compressor. Near the compressor you find two ports, the high port and low port. You can follow the compressor line to reach the port.
To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on. Then turn off the care and touch the lines from compressor to the two ports , often covered with
plastic caps. Only one of the pipes will be cold, the line that is cold will lead you to the low port.
Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
