It says here that one can should do it when you buy a recharge kit from the auto parts store.

The 2002 caravan ac should be charged at the low pressure service port. This port is located on the suction line near the compressor. The suction line can be identified by it's size, it being the larger of the two line connected to the compressor. You must purchase a recharge kit at your local part store, which should include charging hose with pressure gauge and a can of R134a freon. Gloves and eye protection should be worn during servicing.(freon can freeze your eyes and cause frost bite to your hands). Connect freon to charging hose, connect charging hose to low pressure service port, open valves and start engine, turn on ac. If compressor won't start it may be required to disconnect the low pressure switch and jump out the connector.

The PO should also determine if her vehicle uses R134a or the older much more expensive R12. Ralph

Some of that older stuff needs to be captured and recycled too. Is this really a DIY sort of repair?

Cars after 1993 went to the R134a referigerant. And yes R12 or Freon is was banned by the US in an international treaty for it's link to ozone depletion. I think if they actually make recharge kits, it's a DIY job.

If you need more than 2-14oz cans you probably have a leak. O rings at the hose connections can be replaced for $10 by buying a set. A vaccumn pump must be used if system is di-connected at Harbor Freight for $14.Dye can be added with freon to see a leak. Freon sniffers can also be had for $80. http://www.autoacforum.com/messageview.c... best site for "flushing a system." if you dont wanna replace ALL of the parts
