Check the color of the old antifreeze. It is probably red. This would be Hybrid Organic Acid Technology and should not be mixed with other types. 2000- 2001 is around the time that Plymouth changed to this type of coolant so its important to check for the red color.

To get an owner's manual at a cheap price, would be on Ebay. Just type "Plymouth Voyager" and you'll get results. Hope this helps.
A 1991 Chrysler Voyager can use ATF+3 or ATF +4.
