I have a 1999 Dodge Caravan, 3.0 engine. How do you get at the back 2 spark plugs... wow?

Here's the Wiki answer:

"Hey Formuls==The rear ones are HELL. Just get "U" joints and extensions and it can be accomplished. Or don't flinch when the mechanic shows you the bill for changing them. GoodluckJoe

The rear ones are bad but not impossible. If you remove the bracket that stabilzes the alternator (the one that lies horizontal at the top of the engine) you can get to the rear two that are on the passenger side. If you go from underneath the plug on the drivers side is quite accessable (also the middle one is not bad from underneath)."
