What are these lights called?

[tsingson]

Have the plugs been changed?

 

[Trumposarus]

I think roughly 70,000 miles ago. How often should they be changed

 

[tsingson]

I guess it depends. If it were me and I was changing the coils, I would go ahead and change the plugs just for peace of mind.

 

[Trumposarus]

I'll have the labor priced out. I heard they're a pain on the 5.4's

 

[tsingson]

They kinda are if they haven't been done before. I did mine and I broke 7 out of 8 plugs. But you save a lot of money if you do it yourself and you gain a whole ton of confidence when you complete it.

 

[Trumposarus]

How did you remove the broken ones?

 

[tsingson]

The Lisle Tool.

OP has a 2003 with a 2v motor which doesn't have the issues of plugs breaking like the 3v does. OP, just get a universal joint, various extensions, and give yourself time and you won't have any issues. It is time consuming and knuckle busting, but it's not anything that can't be done with basic mechanical knowledge.

Thanks for the info. I tried turning the fog lights on and nothing. I'm going to change the bulbs if the fuse is good.

Well that's even better.

 

[Trumposarus]

Yes it is even better. So now if I can just diagnose the engine noise I made another thread about, the fluid dripping from the tailpipe, the fog lights, and the ac door issue I'll be all set.

Just remember to torque the plugs correctly, use a torque wrench. The 2v engines didn't have the issue of plugs breaking, they had the issue of blowing out plugs....

If you ever experience a spark plug blow out, there is thread inserts that allows you to repair it.

 

[Trumposarus]

Thank you for the information. It should come in handy if I choose to do it.

Exactly what he said. My 99 GT has spit out 2 plugs due to previous owner not torquing with torque wrench. However, from what I understand, Ford revised the heads in the 2003 model year 4.6 and 5.4 to have extra threads. I would still agree with Skauber that torque wrench is still the way to go.

 

[Trumposarus]

Do you know what the torque spec is on the plugs?

 

[46L281GT]

All Data says 13 ft lbs. that's what i did

 

[ExplorerTom]

I did like the video says. Tight, plus a little extra.

 

[Trumposarus]

I will do that. Was anyone able to diagnose the noise my expy is making?
