2000 dodge grand caravan 3.3?

Sometimes you'll get better access if you remove the cowl grill that sits under the windshield or you may also be able to reach the back plugs easier from under the vehicle.I own one and I know what a pain those plugs can be.There is also a wiring harness that connects to the alternater and runs back towards the drivers side.It has a plastic clip that pushes into a bracket near the throttle body to keep it from getting too close to the rear manifold.Make sure you put that back in place or use some zip ties to keep it away from the manifold.I failed to do this and it melted that wiring harness and caused several things to short.Took weeks to trace the problem down too.

A few things on that car. Look at the strut towers, if rusted you may want to get a reinforcement kit put on before they fail. If not then make the water issue is fixed, I think there is some problem the water runs onto the strut towers, do a search on that.

I bet the plugs are real old. They are hard to get to. I think you have to take the wheel off and for one need a long extension to reach the plug from under the car.

Not sure on the cost.

Had an 04 Caravan. Same design.

Jack it up, put it on stands. The plugs are accessible from underneath.

Gotta change the back 3 completely by feel. Can't see around the intake manifold and cowl panel.

your arms will reach back there. harder to get from underneath

also spark plugs
