Charging the A/C system is really simple. I have a '98, but don't know why a '97 would be much differrent. So, see if this works for you.

You will need a charging hose with a guage and two or three cans of refrigerent (R-134A). If your system is out of refrigerent you have a leak. So, make sure one of the cans you buy has marking dye in it so you can figure out where the leak is. Depending on how large a leak you have, it may take several weeks and months or just a few days. Most canned refrigerents have a sealing material that may plug the leak for an extended period of time or even permanently.

With the engine running and air conditioning on, disconnect the harness from the low pressure switch on the accumulator (left side of engine compartment).

Use a small wire to jump acoss the two contacts, the compressor clutch should engage and the compressor should start turning.

With the refrigerent can attached to the low side hose (blue connector), connect the hose to the low side port on the accumulator.

Open the valve on the charging hose. Refrigerent should start flowing. Shake can periodically refrigerent is drawn into system. Can will feel very cold and probably begin sweating as the refrigerent evaporates and is drawn into the accumulator.

There should be technical sticker under the hood to tell you how much refrigerent to charge system with. When it reaches the correct pressure 25 to 45 psi depending on ambient temperature, you are close to the correct charge, (most gauges you get at auto parts stores have a "blue zone" to indicate proper charge) close charging valve and disconnect the hose from accumulator. Though you can't tell exactly how much refrigerent you've put in, by knowing how much is in each can and how many cans you put in you will have a pretty good idea.

This will all go fine as long as you don't have a bad compressor or other sealed system problem.

Good Luck!

A/c recharge car

If you need a recharge, you have a leak. You will be losing refrigerant 24 hours a day / 7 days a week and need to recharge when it gets low. Most garages and shops offer recharging A/C units from $99 and up. You might want to get an estimate to have the leak fixed before recharging as that would be a "once & done" arrangement. If the leak is in a location that is hard to access, it may cost over $1000 to fix - in which case recharging once or twice a year may not be quite so bad.. Good luck!

Mazda6 ac recharge valves

the correct one should be smaller, and your recharge hose should be only able to connect to it. the smaller fitting is the low side, and the larger fitting is the high side. recharge only to the low side. the high side is used by technicians with elaborate ac manifold guages to monitor success. these guage kits can be bought at harbor freight for about 55 dollars,and give a better recharge,as you can regulate pressure as not to overfill, which lessens the cooling
