number of cans of freon to add
How many cans of freon does it take to charge air
Это хороший вопрос?
Unveiled at the 2000 North American International Auto Show on January 10, 2000, the redesigned 2001 Dodge Caravan and 2001 Chrysler Town & Country were released for sale in August 2000.
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.
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
The coolant weight is listed on a sticker under the hood. On mine, it was near the radiator. (1.5 lbs R134a on mine)
Good info if you are starting with an empty system, not so helpful for a partially filled system. Can sizes vary, so the question of numbers of cans is pointless.
Underfilled is better than overfilled. Stop adding when it starts blowing cold if you lack a gauge.
