AC Dryer replacement - when ????

Hi all,

I have a question for the great minds here...I recently purchased a 1995 Geo Metro 3door, manual, 3-cyl (1L).
Thankfully the AC blows cold air, and everything works fine.

But here's the question: does the AC dryer need to be replaced assuming it is still the original one? The desiccant material must be degraded by now - not sure.
It's a fairly cheap part - $10 at rockauto so why not....

So what's the overall guideline for this - if it works don't mess with it?

Just my .02¢... :type
The time to change the receiver/drier is when the system has been opened because the desiccant material will soak up any moisture in the system,
very seldom does a receiver/drier come apart on it's own.
It usually fails because an open system was repaired without replacing the receiver/drier ...
As for preventive maintenance, not really an issue.
You stated the system works good so don't mess with it...

I would also like to know this, last year I replaced the compressor and the reciever/dryer, but settled for a smaller one and I'am not satisfied with how my system is functioning, should I replace the new/smaller dryer with the old one and just pull a good vacuum? And then call it good?

Doubt that's your problem. Who did the work? Did they weigh in the charge?

I did, last year she worked awesome, this year, not so good... I did the work, but I've been sceptical of the #'s because of the smaller dryer, should I just reuse the old dryer?

Sounds like you have a slow leak. Anything wet with oil?

I second this advice. It's not needed.


Dont run if you can walk, don't walk if you can sit, don't sit if you can lay down and if you can lay down take a nap.
