I have a 1999 grand caravan with a 3.8 Liter. with all wheel drive.
I have been under it (having seen some post), over it, in it, I am considering pulling the alternator to see if I can reach the plugs from that end. Has ANYONE done the rear three plugs on that engine and HOW ????? Suggestions PLEASE !! HELP!!! :banghead:

Try the alternator and if that does not do pul the windshield wiper assembley off and go from there.
Also I would change the plug wires at the same time.
And use the OEM champion plugs RN14PMP5 plugs gap at 48-53"

On my 96 3.8L its a bitch getting the back three. I did it from below once but last time I took intake off. Sounds hard but isn't. 4 bolts hold big part of intake to a small valley intake manifold. You dont have to take this valley intake off the heads. Only other part is disconnecting egr line from bottome of intake by throttle body.

It is a whole lot easier with this upper intake off.

remove the throttle body and there is a bracket from plenum to head must remove then remove coil pack and remove upper alt bracket and there you go
