94 Caravan, Is there a kit

Do a google search on this group. There are lots of posts.

To recap...

In order to properly recharge your air conditioning system, you have to evacuate it with a vacuum pump to remove everything from the system

- especially all the AIR that is in the system.

THEN you blead refrigerant into the system.

You need to ensure that the system will hold the vacuum before recharging - this proves there are no leaks (well no major ones at least).

And, of course, all of this must be done with the correct equipment and with the local (EPA??) Environmental Standards applied! You cannot just vent refrigerant into the atmosphere.

In English....

This is NOT a do-it-yourself project. Go to a certified A/C shop and let them do what they do best.

If you try to save a few bucks with a $10 can of refridgerant from Auto-Zone or Canadian Tire, you will likely cause the rapid demise of your entire A/C system - then is will REALLY cost you!

YMMV
