i got a 4.7 and am installing new spark plugs tommorw. anything else that would be good to do while im working on it

 

Maybe wires?

 

clean the throttle body.

Not sure when you've had the fluids changed but,

coolant
motor oil
Transmission oil
transfer case oil
Front diff oil
Rear Diff oil
Power steering
Brake fluid


that should keep you busy, or you can just change the plugs lol

 

Remember anti seize on the threads.

 

4.7'S dont have any wires to change

 

A universal joint for your ratchet will make the back two plugs much easier. Anti-seeze on the threads. Don't over tighten the plugs. That's about all there is to that.

The 4.7L doesn't have spark plug wires. There are coils over the plugs. When I was last in Napa I asked about how much they are and the guy told me $31 EACH!!! That's almost $250 for 8 of them. Anyone have any idea if you are ever supposed to replace them? Need to see how long I have to save up.

 

They r $120 on ebay

 

It's pretty straight forward deal. Pull the coil, pull the plug. If I could make one suggestion. At the bottom of the coil, spray it with air or something. If you pull the plug out, it's very easy for dirt, etc. to just fall in the cylinder.

Hey, 4.7's on a side note.......we got a new 4.7 club getting started, feel free to join in.

 

well i got the plugs took alot longer and i had remove alot more then i thought it would. but they definetly needed to be changed have 150,xxx miles. The gap is supposed to be .40 but the ones i had taken out were at .80 and pretty burnt up they definetly needed to be changed

 

whoaa, 150k on the original plugs. has any other maintenance been done to the truck? i.e.fluids or anything else? Pretty much everything is due EVERY 30kmi except the trans fluid.
