Hello everyone. I am getting ready to do a tune-up on my truck and I need to know how to change the spark plugs. Can anyone help me?

 

If I had a 4.6 I would help you I have a 5.4 but it should be here somewhere just do a seach for it have a good one

 

Lefty loosey, righty tighty. What exactly do you need help with?

 

I might add, you need a great deal of patients.

Have you ever changed plugs in ANYTHING? Just the way the question is worded kinda scares me. LOL

Could you be more specific as to what is questioning you.

 

I just wanted to know where exactly the plugs are. i don't see any plug wires just looking at the intake side or exhaust manifold side. If i knew where/how to get to the plugs i can change them my self. I help my husband with all of our vehicle maintenance to include 2 trucks and 2 motorcycles.

The hardest part is getting a bite on the plugs. Other than that, its not that hard. Hardest part is in and out!

 

Or fishing the sockets out that fall down underneath the plenum

I tape them to the swivels and tape the swivels to the extensions when removing the accessories to get to the plugs..

I still have a few 7 & 8 mm sockets under there

 

Thanks. My husband keeps saying that they are different because my truck doesn't have plug wires.

 

NO 5.4L used plug wires. The 4.6L DID have plug wires until 2001. In 2001 your motors ignition was updated with the same ignition as the 5.4L. Since 2001 they are one in the same. You have the same Coil Over Plug ignition as the 5.4L (COP)

Sounds like he needs a "heads up" - help him out

Follow those instuctions I posted above and you'll be golden.. ( :

BTW - At the top of the page - Look in the "technical articals" . That's where I found the info..

Good Luck.

 

You will need different length extensions and a swivel is helpful. If you have cop ignition there is a small screw that holds the plug wire on to the plug. The boot has a long spring in it that attaches to the plug. Depending on the mileage of your vehicle, the plugs may be really tight. I have read of plugs seizing in block. The main thing is to make sure you keep socket and extension as straight as possible. You will need a plug socket with a rubber boot in it. You should also use some antiseize on the plugs before you put them back in and use some electrical grease on the sparkplug boot. A magnet is also helpful when you drop the little screws that hold the plug wires down.

 

Nope no screws holding any wires. You don't have plug wires..Just a 7mm bolt that holds the COP in place. It rides on a bushing. Your plugs don't have any seizing issues and I don't suggest using anti-seize on your model. They don't need any help coming out.

Don't get confused by this poster , he doesn't know what he's talking about

 

X2 on the ANTI-SEIZE. Those buggers will some out when they get the notion to in a 4.6. LOL

I do mine WITHOUT a swivel, BUT, I have the older version with wires. So, that may be exactly why I don't use a swivel. LOL I have also learned that taping the socket to the extention (or swivel and extention) will save a few curse words from flowing out during this process. LOL I think jbrew mentioned that as well.

Good Luck!
