There are some articles on the Internet that explain how you can add Freon to a Dodge caravan, and they are incredibly detailed. Websites like eHow offer step-by-step guides on how to do this, but you should only ever attempt to do it if you are really experienced in this kind of thing. If you try and do something like this then you could easily cause a number of problems. Owning a Dodge caravan is something many people will be proud about, no doubt including you, so there's no reason why you should do something that could damage your Dodge. You should be doing everything you can to ensure that your Dodge remains in good shape.
So what can you do? Perhaps ask a couple of forums. There are many forums out there that deal with Dodges and the amount of people on there means that there is bound to be someone who is able to tell you precisely where that connection can be found. All you need to do is find the forum you want to be involved with and join. Make the minimum amount of posts that are required before you can start a thread, and then start your own thread asking this same question. It will mean that all of the people on the forum who know the answer to your question will be able to get in touch with you and help you solve the issue.
You could always go and see your mechanic, too. Your mechanic will know the ins and outs of your vehicle and will easily be able to perform this for you, without damaging the vehicle. It's probably not worth you trying to add Freon to your Dodge caravan, as it would simply be too risky.
