AC recharge/lubrication, any good?

[Hugger3800]

Wondering if those little recharge/lubrication cans are any good for an A/C system or they harmful?

[Bliggida]

they are for only if you need them.

If your A/C pressure is down, a can of refridgerant with some oil in it wouldn't be a bad idea.

But you DO NOT want to over-pressurize the A/C system.

How would I know if I was low or if I was over pressurizing the system?

Hugger3800,

Depends. If your A/C system is solid and is just a little low on 134A then a simple recharge is valid.

I have not had to do anything with my Camaro yet, but I also have a Fiero. If you know anything about Fiero's then you know that they are very high maintenence vehicles and that includes the A/C system.

Recently I had to charge (read top off) the Fiero system. Most Fiero A/C systems leak and leak around the seals for various reasons. There is a product out now that is a complete recharge package for under $20 and you can get it from Wal-Mart as well as most auto stores. It is a one can unit with a pressure gauge on top and mixed with the refigerant is a leak detection dye and compatiable 134A oil and a leak stopper (seal expander). The recharge instructions are complete and simple. The gauge is transferable from one can to another. I used this system a month ago and the A/C system will now freeze you with the outside temperature above 95.
