[i]Little bits
On replacing spark plugs: “On the Caravan with the 3.3, take the bolt out of the front engine mount by the radiator and let the engine rotate forward as far as possible and then set the parking brake. Watch for clearance as you push the car in park and it will work. You can then use a socket extension straight down on the plugs and reach them easier.” (from Ervin)


This quote is from the repairs section of allpar. Has anyone that posts here tried this? I'm wondering if you still have to remove the wiper cowl and/or air plenum when using this procedure? Seems like might be a time saver and potentially easier than crawling under the car to reach around the catalytic converter.

For which generation van was this suggested? How does this help in a 96-00? The rear plugs are still tucked behind the alternator, intake plenum and throttle body when the engine tilts forward.

It is unclear from that section which vans it means.
But I never found the ones on my 1991 3.3 too hard to do.
And it's pretty quick and easy to get the stuff out of the way on the 1999 3.8 for that once per 100k change.
I think the time spent messing with the mount would be better spent on other parts of the plug change process.

In the shop, Some of the techs take off the cowl and wipers to gain access to the
back of the engine for plugs, valve cover, etc..
Once the cowl is off, the back of the engine is very accessible.

I pulled the cowl AND rocked the engine forward...it helps, but still not easy(2000 3.3) actually the mount is easy to tale loose and use a bottle jack or such to put back together.

On my gen 2 97 T&C with 3.8L, I've done it both ways.
As suggested in the OEM manual without removing the cowl; difficult, time-consuming, many scrapes, cuts, etc.
With cowl and windshield wiper module removed to r&r the alternator; a lot easier.
Removing and replacing the cowl & ww module really doesn't take that long to do.
If I make it to my 4th set of plugs, I'll do it that way again.

I read as much as I can in the forum and other sites before I attempted to replace the 3 rear plugs on my 99 Grand Caravan. I was contemplating which of the two most common methods 1) removing the wiper tray or 2)doing from the underside with the van on a hoist. I was lucky enough to able to use my friend's hoist in his shop. My conclusion is that if your GC have the optional two (Front and rear) air conditioners, you will never able to get to number 1 (passenger side)plug from below because the refrigerant tubes. You have to remove the wiper tray and alternator bracket to access to it. It turned out removing the tray was easy just time consuming.

Good luck.

I came across this post and thought I would pass along my experience. I just finished replacing the spark plugs and wires on my 2004 Chrysler Town and Country with 3.3L and 93k miles. I accessed all of the rear plugs from over the top of the engine without any major difficulties. I was getting an check engine light error P0304 which I hope solves the problem.

Absolutely. The Gen. 4 vans have far better access than the Gen. 3s! Good luck on your CEL.

your forgetting about an engine... the 3.0L Mitsubishi 6G72. the Flat Plenum makes it easy to stick your hand between the cowl and the engine down to the rear plugs. believe me, I've had to replace the plugs in ours.

Replaced plugs on our '05 GC with the 3.3....just reached over the top of the intake...not too hard at all. My dad has a 97 Plymouth Voyager with the 3.0...now those are hard...not as much room.
