How much Freon to add and what kind of Freon?

need more info, what kind of freon? What tools are you using? Have you talked to the store you bought the freon from?

If you mean freon, probably not.
It depends on what kind of freon is used. It takes a license to buy most types of freon for household use.

There is no way to know that

If you need to add, you have a leak
& are poluting the atmosphere

Have the leak fixed ,a vacuum pulled,then that
is checked, to see if it holds a vacuum

You can only add refrigerant into a vacuum &
it has to be added with a scale in oz's to get the
correct amount or you over charge & could ruin
the system

If you try & add some,you will let it into the atmosphere,
as well as let air into the system.

Hi bennysosiris...
If your compressor is starting and stopping regularly and it is not blowing cool as it one did then I would say:
Yes you need to add some freon to your system...depending what kind of freon it takes if would be better to take it in to have a professional install your freon to the proper pressure and volume.

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.

Its calling for more freon when it kicks on and off. Add Freon.
You can buy freon at most any parts store.
Make sure of what kind it is. R-134 or r-22 Look under hood for the designation

You can purchase R134a cans with a built in gauge so you don't overcharge... Assuming the system has not completely discharged, usually a can or less will do. Here is a link with some basic instructions:

Before you add Freon, you should check the leaking first, if the Freon is too low, sometimes cause this kind problems. use color Freon test it and tight the leaking area and then add Freon, you can not do it yourself because the law say.
