A/C recharge

Has anyone every bought a kit to recharge an A/C system r134? Is it as simple as they say and what's to watch out for?

Thanks

Well, the simple kits they give you are easy to use, BUT, to get a true A/C pressure test, you need a manifold gauge set which can be fairly expensive. This set will get the High and Low side pressures.

To get an fairly accurate reading of the low pressure side, the engine needs to be running and AC on max. You just connect your little gauge and hose coupling to the low side port. (It will only fit low side)

Do you hear your AC compressor/clutch engaging? It will make a clicking noise when you turn it on.

Thanks, I got the kit and put in under 1 lb and it's freezing. Saw a kit from castrol that has dye in it and ordered it for next time when I'll wind up replacing o rings.

Am I missing something here?

If the A/C system lost refrigerant, doesn't that mean that it is leaking? If you recharge it, won't it leak again? Why would anyone re-charge the A/C without first replacing the parts that leak and isn't that a prohibitive cost usually?

quick, you are correct.

89mercury,

That is not the best idea too do. You just don't keep dumping in cans of 134 without having the proper manifold test gauges available, not those cheap $10 gages you get with the cans.

If there are no leaks, there is no need to add refrigerant. If you are having to add refrigerant, you have a leak that needs to be addressed.
