How do you change the rear spark plugs on a 2002 Dodge Grand Caravan 3.8L. I've looked from below and it's too far up in the frame to reach??? Thanks in advance

    Actually, this one was fairly easy. I'm a seasoned "backyard" mechanic and have worked on numerous front wheel drive vehicles with the back spark plugs always being a challenge.



    Solution on the '02 Dodge Grand Caravan - 1. remove the air cleaner cover and filter. 2. remove the rubber hose that goes to the throttle plate 3. Remove the throttle plate assembly. You can now put one arm through that space and the other arm through on the right side of the plenum (top plastic piece that says "3.8 V-6". You'll basically be hugging the motor, but even with my big arms I had no problem reaching all the spark plugs and even tightened the valve cover bolts from there. You just have to be careful when you start threading the new plugs as to not cross thread them because you're doing it by feel. Mine went right in, no problems! Happy Wrenching!

Unfortuneately......there's no easy way around this. You need to have 3/8 drive extensions and wobblies so you can navigate around the right bank to get those plugs in...it's a bad design.....but the only way it can be done in a timely manner is by the topside....sorry to tell ya that....hope i could help!!!

Take the front motor mount aloose looks like a dog bone this will enable you to pull the engine forward enough to get to the plugs in the rear of the engine.

How do I change the rear 3 spark plugs on a '94 Grand Caravan?


Yes, these are tough to get at from the top. Put the front on jack stands or ramps, and you can reach them a little easier from the bottom. You just need to reach up where the exhaust pipe comes down, and you can even see what you're doing this way.

Heater fan regulation


2002 Grand Caravan. The rear heater also has a resistor for the fan speed control.(3 speed) It is located under the rear passenger side plastic cover. You can take off the rear tail gate lower plastic piece and this will let you pull out the side panel. You can reach in and take out the two screws that hold in the resistor and unhook the wiring adapter. You do not have to take off the whole side panel as you can reach in from the back. The resistor unit can be bought at you local dodge dealer.
