Answer r-12 r-134 freon a/cIt is kind of easy but is best with 2 people. First buy the box of r-134 a/c recharge kit , it has 2 cans of freon, the valve nozzle , hose, and the converter attatchment for the r-12 systems.I have found this for $35.00 at the MART that starts with a "K" (hope this was not considered copyrighted text), plus buy one can of oil charge and one can of leak seal. (not that the box kit is only a one time only purchase and can be used on mostly all vehicles). Than (always wear goggles and gloves) remove the (2) valves stems on your vehicles a/c lines. Have another person have the ide at around 2000 rpm (and with the a/c on), (if your compressor is not REMAINING on than hook up a direct wire from battery to compressor (it might be a pos. and/or a neg.,lots of types of vehicles) than with an ink pen press in the tips of the valves until it is all (ALL) empty, and the valve that has the old freon spraying out is the high pressure valve(freon will be hot). Then to fill, (freon only goes into the LOW pressure valve. First use one can of freon (upside down, and some will spray out of can IT WILL BE FREEZER BURN COLD, than one can of oil charge, than one can of leak seal. if the a/c is a little warm than add the other can of freon, but if the a/c is cool, than that is probably enough,(too much will pop a hose line). Note that this is an at home procedure (not from a professonal) so do not expect the a/c to be cold like factory car lot cold. If you think you may have a leak but need to find it, only try the first can of freon to (hopefully) find the leak, or of course you will lose all of what you put in when you repair the leak. Also it is a good idea to buy the freon pressure gauge at the same store ($7.00), it is good so you do not over fill, it is easy to overfill by accident and possiby crack the compressor. Good luck and have a cooooooool summer.

Allot of auto parts stores will sell a kit with only one gauge. You need two gauges to properly add Freon to your car. It is also a good idea to evacuate the moisture from your compressor. This is esp. true if your AC was working and slowly got warmer and then blew only hot air out of your vents. All car AC systems are 'designed' to loose Freon due to the flexibility of the seals in the compressor. If you don't have an evacuation pump, you buy a a Moisture Flush can/kit that costs approx 5.00 at an auto. This will ensure you compressor. If you car does not have a tachometer (there are quite a few budget models that don't it east to guess what 2000 RPM is. Put your foot on the gas approx. 2 steps and your engine will be hitting in the area of 2000. The important part is to rev your engine during the process.

There are some great videos from Scotty Kilmer on YouTube on recharging your cars AC system. Mechanics will have you believe they are the only ones qualifies to do it, but with proper planning, reading all directions, watching youtube videos you will save hundreds and have a cool summer.
