How to Change, back three plugs on a 2003 Dodge caravan 3.3l

Lower Intake:

1. Use a skin coat of RTV silicone on both sides of the water passage ports (outer most holes) and put the new lower intake gaskets into place
2. Hand tighten the 13mm head intake bolts and Torque the bolts , starting from the center and working your way out in a circular pattern
3. Torque these bolts in a few small increments until they have reached 250 inch pounds of torque.
4. Upper Intake Plenum:
5. When installing the intake air plenum , be sure to catch the four center bolts and the two side bolts (stiffener brackets) before tightening , The center bolts should be torqued to 250 inch pounds .The fuel rail bolts should be torqued to 100 inch pounds

you will need a swivel 5/8 spark plug socket with a short extension reach over the top of the intake manifold it is not easy but it can be done

in the 4 cylinder they are located in the front of the motor just beside the exhaust manifold, in the 6 cylinder. they are in the front and the back (three per side) the rear plugs are hard to get to in that you need to reach far behind the motor but your arm will fit.

this will help, Good Luck Tim:

You actually do see them you just don't realize it. When you look at the motor from the top down you should see what looks like caps with wires running to them evenly spaced across both cylinders. You ahve to remove the retaining screw and then pull those up. Those are actually the independent coils that ford uses on top of each spark plug. You'll need a socket and extension to reach the plug itself, also, if you have the 6 cylinder motor you'll have to remove the upper intake in order to reach the the plugs nearest the firewall. On there were 6 retaining bolts for that I'm not sure about the 2003 because of design changes. You don't want to remove the intake manifold itself, just the top half of the intake itself.

I was working for a company that used 1995 Caravan's for their sales force and I do not know of any sensor. I am confused by the term "cover".

Do you mean valve cover? If so does the sensor go somewhere? I can solve your problem, but I need move info. Please call or email me.

Either,way let me know the outcome. Your feed back is my only reward. Also, please rank my answer with as many thumbs as you think I should get.

I understand the coolant temperature sensor on a 2003 caravan is located just under the coil.
There are two sensors located in that position, it's the one toward the passenger side of the car.
I'm changing mine in the morning so I will know for sure and if it's not there I will return and correct this post.

Replacing spark plugs (2003 caravan); can be done from the top, reach around the engine (not over) from the transmission side to get to the rear spark plugs, I have done this twice.

The upper part of your intake manifold needs to be removed.I think Chilton lists spark plug replacement on your Caravan at something like 3 hours.

Remove the Caravan Ignition Coil Step1 Look under the hood for a distributor. The spark plug wires connect into the distributor cap. If you don't see a distributor, you may have a model with a distributorless ignition system. Step2 Find the ignition coil. On a Dodge Caravan, the ignition coil is at the back of the intake manifold. Disconnect the negative battery cable to prevent injury while you work. Step3 Determine whether you need to remove the windshield wiper/motor module assembly. This won't be necessary on all models. Step4 Disengage the connector securing the wiring harness connector to the Dodge Caravan ignition coil. Then, disconnect the ignition wire from the ignition coil. Step5 Use a socket set to remove the mounting bolts. There are upper and lower mounting bolts. Separate the ignition coil from the mounting bracket. Install the New Ignition Coil Step1 Insert the new ignition coil. Mount the Dodge Caravan ignition coil to the mounting bracket. Step2 Attach the mounted assembly to the intake manifold. With a Torque wrench, tighten the fasteners securing the ignition coil to the mounting bracket with 96 inch pounds of torque (10 Nm). Step3 Tighten the bolts that secure the intake manifold to the bracket with 115 inch pounds of torque (13 Nm). Step4 Connect the wire harness and any other parts you removed, including the negative battery cable.

hi the front ones are not bad but the back ones you will have to get from under the van.( do them one at a time)
