Question on refrigerant for my 2000 Chevy Tracker

[leroy_haines]

I know this sounds stupid, but I'm on a tight budget and I need to save all the money I can. I was wondering if the Sealant/Refrigerant combos were really worth the money and also how many ounces of refrigerant does a 2000 tracker hold? Any suggestions and brand names would be extremely helpful to me at this point.

If you ever want a good shop to service your AC again or be able to have it worked on again, NEVER use a sealer/sealant in your system. Most of that stuff is more like a glue that when it comes in contact with air plugs the leak and when any air gets in your system will plug the whole works. It can really foul up a shops AC service equipment too. Its best and even cheaper in the long run to find the leak and fix it.

Thanks so much for the advice. That was something else that I had in mind and I actually have a friend that has a "sniffer" kit (I think that's what he called it) that can help me to find the leak. Now I know for sure what I'm going to do!

A can of R134-a is around 5 bucks.

You cannot properly and safely recharge an air condition system with them.

The one side stop and go gauge does not tell you what your system is doing or is over charged or undercharged.
A overcharged or malfunction air condition system can reach over 500 lbs of pressure.
Enough to blow up that can or system and freeze you at first and the burn you or blind you and if any propane /butane in there blow and light you up.

The stop leak crap and who knows what kind of oil in the kits there will stop your system for sure.
Just like pouring super glue in it.
And some kits even contain freon with a butane mixer.
Good for a big blast.

If you are going to do it do it right and safe.
Here is what you need to start with.

In the older days you could just throw in a can and go.
But over the years just adding freon is getting harder to do.
Newer systems have to have the correct amount of freon down to the ounces.
Most will need pumped down and vacuumed down and the right and amount of oil and a set amount freon charge installed to get the air to cool right and the system to last.
If an air condition is low there is usually a leak that needs fixed and also a lose of lubricating oil from system.
Also air and moisture enters a low system
If you are going to try to do it get the proper type air condition gauge set with the low and high side gauges.
Hook up the gauges and get a reading with compressor running at idle and at 2000 rpm on the high and low side.
Post back pressure reading and we can help you.
