Depending on the size probably 2 or three. Due to the age of the system unless rebuilt, I would start with the large can with "sealant", which usually has a pressure gague includeded. If that is not enough to bring it up to "sufficient" charge, continue with a smaller regular can. etc. If you have a serious leak, no size of can will help. My 20 hr old car is still holding with the above treatment several years ago.

1999 acura cl wont;; hold a/c charge. have to put 134 in it

if it did not have r134 gas before DO NOT put r134 gas in now. The r134 runs at a much higher pressure and you need new condenser/evaporator and compressor to compensate for the high pressures generated. have an A/C technician explain it to you

What type of refrigerant does a 1990 Ford Ranger use?

there are only two types of refrigerant (or normally called as freon): R12 and R134. R12 is designed for car model 2000 and below. though, some old car compressors can accomodate R134 provided that you change your auxillary fan (fan for your aircon condenser) since R134 is hotter than R12. Ask an aircon technician if your compressor can be charged with R134.

Most of the countries now ban the use of R12 since it is more harmful to our ozone.

Im trying to recharge my ac in my 1995 audi 90

buy r134 can w/pressure gauge at local parts or department store. Folllow directions on can as far as application. The valve only fits the low pressure line, so there is no way to accidentally attempt charging high pressure side. Unscrew cap, attach valve of r134, check gauge. if fully charged already, do not overcharge... won't cool better, only cause damage.

If my air conditioning condenser is damaged and the air conditioning system now fails to blow chilled air, is this a loss of Freon? If so its poisonous, so I am under the impression I should not attempt to...


The freon is not poisonous. The gas currently in use is the R134 (no HFC's) replacing the old R12.

You can replace the condenser and then you have to charge the system with the right amount of gas and some lubricant.

1989 Chev PU , Aircon Dead , Want to Convert

Anyone can convert R12 to R134. It is as simple as screwing the two adapters on the low side and high side charging ports. Now to charge it you need to evacuate it as you said and then charge the system with R134. The hardest part is finding the way to evacuate and then recharge the system without going to a repair facility.

Does a 1991 accord use r134

Most likely it uses R-12. If it was converted to R-134A, it would have at least 1 sticker (usually 2 stickers) indicating a conversion to R-134A was done. The sticker would be on the chassis and would be visible as soon as you open the hood. There could be another on the low side AC line where the charge valve is.

A/C Problem

Check the fuse to the A/C and if theat's good, then it's a good chance that the A/C system needs to be re charged with R134. Yours is a 1993 so it was the change over years from R12 to R134.
Your going to have to find a sticker somewhere in the engine bay that would indicate what system you have. If your have the R134 then you can buy the  re charge kit. If your system is the R12, your going to have to take it to a shop and have them convert it over to a R134 system. 
Good luck and keep me posted.

AC does not work

Check the fuse for the A/C and try refilling the A/C with R134. You can buy the re charge kit at Auto Zone or Wal Mart, almost any Auto parts store. If the system is low on R134 the A/C compressor will not activate to keep it from burning out.
Try checking the fuse first then re charge the system with a can 12oz of R134. Just keep in mind not to over charge the system. Just follow the instruction and you'll be fine.
Keep me posted, be glad to help out.
