Air Conditioning - its hot out!

[NTIman]

I wouldn't be concerned about the dryer if you get the system evacuated as much, when you evacuate the system, the vacuum pulled on the system boils the moisture out, and as long as you don't have a major leak, you're probably ok not to replace it, although, while you spend the money, it wouldn't be a bad idea to replace it just to make sure. You may as well take it somewhere to get it evacuated properly, otherwise, you may not get all of the moisture out in the first place, even with a dryer.


You can install the dryer at any time, as long as everything is sealed up ok, however, make sure you don't use the AC while you have no refrigerant.

Most TOYOTA compressors come with oil in them....I DO NOT know about other manufacturers compressors, make sure you find out before, too much oil is just as bad as not enough, because you're going to put in the maximum amount of refrigerant, and AC pressures will get too high with too much oil, and then you blow a seal, and you're back to sqaure one.

MAKE SURE you lubricate the O-rings with whatever oil is suggested for the system....otherwise they will leak.
