I have a 2006 2500 hemi 4x4 HD. is there any secrets when changing the spark plugs. do i need to take out my master cylinder to get to the back 2 coil overs?

 

just do a search man.....

No need to remove master cylinder.....no need to remove anything other than the coil packs. Need a few different size extensions, swivel joint and a spark plug socket.

Oh yeah and a little patience, it's not bad though. I found it really helps to put a piece of foam across the top front of the motor where I was leaning in the whole time, and one on top of the bumper. Less wear and tear on the ribs and knees

 

There are tons of threads on this.

I found it easiest to remove the front tires and wheel well liners and got to them without a problem from underneath. Being lifted 6" made it a pain to get up on top of the engine to get to the back ones.

Oh, and get 2 3" extensions and 2 wobble joints

 

I used two 6's and a 2 , 3 inch extentions. One swivel and a magnetic retriever. The trick is to break the seal of the spark plug unscrew it. Then as you lift it out separate the socket from the 3 inch extention , All the while ,holding on too the spark plug socket. Your gonna drop it. thats what the retriever is for. Repeat the process too install. By the time you get good at it. the rest are waiting for you. But much easier. I did the hardest ones first. 5 hr install. No hurry just took my time. Hope it helps.

 

I think you will have to do 16 plugs and what the guys above said is good and you should also apply some dielectric grease to the threads of the new plugs before you put them in. Oh and if you can blow out any debris that may be in each spark plug hole.

 

Ouch.....talk about trying to do it the hard way (removing master cyl and booster)......LOL

No kidding. Go through the wheel wells. you will be glad you did. it gives you much better access to the plugs, especially the drivers side back 2. for tools, you only need 1



KD tools 3 piece socket set from Sears

the mid length one is just the perfect height to clear the neighboring coil pack and short enough that you can get the plug out without disassembling your ratchet/socket combo.

built in swivel head and magnetic plug grabber. I use a set of these and a 1/4" socket in 10mm for the coil packs, and thats it.

 

I worked for a Dodge Dealer for a while as a service writer, all techa know changing the plugs in the hemi are a pain. Patience is needed, the book pays 3 hours to change the plugs. According to Dodge training you do not remove the master cylinder to change the plugs. As many have stated above its a matter of using the right combo of extensions and swivel head. Also the hemi is designed with 30,000 mile plugs on the top and 90,000 mile plugs on the bottom side. Good Luck

 

Thanks for the heads up. I was hoping i didnt have to take off the master. but like you said patience. if figured it would take awhile. I just wanted to make sure i didnt have to do anything different....Thanks again,,,,

 

I thought all of the plugs were the same?
