How do you change spark plugs on a 1998 dodge avenger es?
- There is quite a few steps in the process. While you are doing the spark plugs it is a VERY good idea to do the spark plug wires as well. You will also need an Intake Plenum Gasket
- The front 3 plugs are easy to get too, right in the front. But the back 3 are under the intake plenum...
- To remove the intake plenum you need a 10mm, 12mm, and 13mm sockets. - You need to remove all hoses and connectors attached to the intake plenum, along with the throttle cable.
- Its best to take out the intake tube as well. 2 10mm hose clamps to loosen, and take off.
- You got 7 12mm bolts in the front, 2 12mm in the back
- 2 13mm bolts in the back on the EGR pipe.
- 2 10mm bolts on the fuel rail to remove it from plenum
(That's as accurate as I can remember)
- Once all that is done, everything is exposed.
- Remove the plugs with a spark plug socket SLOWLY so you don't strip the threads inside the cylinder head.
- If you do the wires, only do one at a time. Be sure to match the lengths of wires.
- When you put the the spark plugs in, put anti-seeze lubricant on the threads of the plug. Tighten them slowly. They torque to about 13 ft-lbs.
- When you put everything back together, make sure that plenum gasket is in place(You can secure it with 2 bolts on the ends) (Plenum bolts torque to 13 ft-lbs)Also make sure that you have every connector and hose back in place. **Check, double check, triple check everything.**
Hope that helps the best way I can describe.
This is an understandable question. The quick answer is, unless you own a repair shop, let the dealership do it. The V6 must have two of the engine mounts disconnected and the motor tilted to change 3 out of of the 6 plugs. Also, insist on platinum plugs or better, and bring your wallet. The plugs are around 13 dollars each and the amount of labor involved is incredible. Sorry I didn't have better news…
On a 1998 Dodge Avenger what are you suppose to take off to change the spark plugs Ive looked everywhere for a diagram but nothing you were told the plenium which you assume is the silver cover above?
I have a avenger with 211,000k and when i first picked it up i had to change all the plugs..WHAT A NIGHTMARE its the most rediculas crap in the world. You have to basically take the whole top end of the dam engine off. Its a joke it took forever and a lot of bloody knuckles and cursing!! All for three of the six plugs. I'm sorry and feel bad for you. Good luck!
You pull the old plug wires out, use your Haynes or Chitlons repair manual to discern what size the head on the spark plugs are. Get a long enough extension with the correct head size socket, put it where the spark plug wires were, put the wrench in reverse and back the sparkplugs out. Put the new spark plugs on the socket, put the wrench in forward, tighten them to the torque specs in your…
