How to Replace Spark Plugs Correctly • Dodge Ram 1500 4.7L

I apologize for the wind noise and background noise in the video if it’s hard to understand me. I really didn’t think the microphone would pick up all of that with the filter on.

Quick walk through of the proper way to swap the spark plugs on your 3rd Generation Dodge Ram 1500 with the 4.7L engine.
This process can be applied to the 2002 to 2008 3.7L, 5.7L Hemi and 5.9L Magnum Rams as well, along with other vehicles.

I have an 2003 1500 4.7 dodge ram. I am having that low idle engine running ruff and stopping problem. Some say it's "air idle control valve" on the throttle body others say replace the engine. Are you familiar with this problem? If so what would you suggest? Thank you in advance. Great video I plan to replace my plugs this week just to tune things up, I just bought this truck 83000 miles thinking it could be the original plugs…

Kevin Douglas says:

Great job !!! I went out and did the job with confidence. The back ones were a fight, but after lots of trying different extensions, I managed to get them. At least my spark plug socket had a good grip on the plugs. Thanks again. Keep making your videos.

Adam Fluff says:

Hey man, I have a 2004 5.7L, got a misfire code and noticed water in one of the spark plug when about to change, could this be something serious?

Matt The mann says:

Thx so much I just bought an 05 1500 with the 4.7. It hasent been started or driven for over 10 years. It has 10k miles and is in factory new condition. Would you please help me with a starting and maintenance procedure. Im changing all fluids dropping gas tank empty it clean it out with kerosene maybe? Then putting it back in with new pump and seals. pulling plugs and put a shot of some sort of penitrant in each cylinder then seal her up put in new battery and fire it off? Maybe run it for a few seconds look everything over then start again and run for a few min. Again im no mechanic just a dumb guy on YouTube trying to learn how to work on my new to me truck. Thanks for any advice help or wisdom you can offer.

Adrian Martinez says:

Hello question. I have a 2011 ram 1500 4.7L 110k. Never charge spark plugs before. I call the dealer they told me I need 16 plugs 8 for intake and 8 cylinder. They told me both are different. Of course dealer price was $$$ so I went to. Advance autoparts the person at the counter told me the yep I need 16 but the are diferent part # ok. This where I get confused. Went to autozone and orreallys and the toldme the 16 plugs are the same part number. That is the same sparkplug in all the cylinders. So I don't know now. Can u tell me is all 16 are the same. If the do. What part # is. Or if are different. With parts # are. Preference mopar o NGK. Thank u so much.

Greetings and good video, I have a Ram 1500 4.7 2004. when I start the engine. I have this problem, the RPM does not rise more than 600, I do not have the engine light on, it could be something related to the spark plugs. Is it necessary to check some sensors that can make this failure? Thank you, I await your comments.

Glen Martin says:
