What type of refrigerant do you use for the air conditioning for a 1991 Cadillac Coupe de Ville with a 4.9 liter?

How do you refill a 1988 Chevy van with freon?

Unfortunately, if the air conditioning system is factory original and has not been converted to use the new R-134a refrigerant, you cannot refill the system yourself. R-12 refrigerant is the old stuff, it must be charged by a professional and will be very expensive. They quit making it almost 15 years ago. Depending on your location is could cost upwards of $300 to get it recharged, and if the system is low then you probably have a leak somewhere so that might be $300 out the proverbial window. If you plan on keeping the van, I would suggest that you convert the system to R-134a. A local air conditioning shop can do this for you. I will cost more than just a refill of R-12, but in the long run, it will be much cheaper as the refrigerant is MUCH less expensive should a leak develop.

The Freon is added through the low side ac port. Using the proper type of Freon and a gauge, fill the system to the recommended pressure.


How do you engage the AC clutch to refill the system?

You don't need to engage the compressor clutch to recharge the system. In fact, you shouldn't engage it without refrigerant and oil in it, because the refrigerant carries the compressor oil in order to lubricate the compressor. But, to answer your question, you disconnect the low pressure switch, and run a jumper wire between the two female ends of the connector.

How do you install freon in a 1999 ford escort zx2?

Most modern cars use R134a refrigerant. My 1994 Escort uses it so I would guess your 1999 does too. You can buy cans of the stuff from WalMart or any auto parts place along with a refill kit. A can of refrigerant will only cost $10-15 but a kit might cost $30. The kit has instructions for refilling the refrigerant for the A/C. There is a low pressure and high pressure valve on the A/C system - the adapter in the kit will only fit on the low pressure side. Anyway, it's easy if you follow the directions in the kit. My Escort A/C system has quit twice and refill of refrigerant got it working again. I used the refrigerant that comes with some sealer as well in case it was leaking slowly.
