How Do I Change Spark Plugs On A 2002 Dodge Caravan?

As complicated as it sounds,this is still easier than anything else that I've tried.
-disconnect catalytic converter
-disconnect front engine mount
-loosen the 2 other mounts
-with both front wheels off the ground and tranny in park rotate engine
       forward and block it.

I was able to pull the van up on ramps and reach up and remove the plugs and wires. It wasnt an easy task but it worked.

I haven't done this yet, but I have seen this for T&C's in two other sites: 1. Leave van parked on ground. 2. For safety, remove positive (+) harness from battery.  3. Remove both windshield wipers. 4. Remove 6 fasteners securing the wiper grill work. Remove grill. 5. Remove 6 fasteners securing wiper grill tub assembly. 6. Carefully disconnect wiper motor electrical harness and the wiper fluid hose. In 20 minutes or so everything between engine and the automobile firewall is now exposed, including the PVC valve (replace it if need be). Protect your fender paint with a blanket. Insure new spark plugs are properly gapped (yes, we all know the spark plugs come from the factory gapped perfectly for your car but the box could have been dropped on the floor or counter so the gap is now ZERO. My 2001 gap is .050 inches for a RE14PLPS plug (my concern started when I found one of the front plugs had not been tightened, the gap was .070 inches, and the plug threads were dry).

If this is a3.3 liter you can remove the belt then the altenator and the altenator bracket on the right side also remove the windshild wipers the torque star screws to the wiper cowl now remove 3 hose,s wiper fluid hose and 2 drain hose,s at the bottom of cowl now remove the bolts & connecter to w.w. Moter and disconect wiper linkage and remove the bottom of cowl this will give access the rear plug,s good luck
