,
all vehicals are required to use R-134 freon, its the law.
Your unit should take around 2.5 to 3 lbs of freon, exact amount should be listed under the hood of your van.
Its probably a better idea to let a shop do the work as they have the correct equipment.
Replacing your drier is a very good idea when doing a recharge.
I have recharged my own system, which only took a small amount, with recharge kit from Wal-mart.{in auto section} Cheap
Any large amount needed usually means that you have a leak somewhere.
A/C units are just like your refrigerator at home... you never have to recharge your home fridge, right?? That's because freon does not "go away" or get used up.
If your unit needs freon, have it checked, they will do an evacuation, and test the evac pressure. It should hold pressure after pump is shut off for 10 to 15 min's.
If the pressure drops, you have a leak. The shop will insert dye into your system, and check it with a floresent light to find the leak, or you can charge the system, and use "liquid dishsoap" diluted with water in a spray bottle, and spray the lines and fittings.
If there is a leak, it will "blow bubbles" where the freon is comming out.
Hope this may help
probably r135
The power steering system on a 2002 Plymouth Voyager uses automatic transmission fluid.
Most Pre 94 vehicles use R12 refrigerant..........but you can convert to 134A without too much dificulty.
