I wanted to replace the spark plugs on my 5.3L silverado (2005) - how hard is this job going to be? Have any of you had anyproblems or have any tips that might help me? should i remove the tires?

Thanks

Unless you have something I dont have it is a peice of cake- socket and a u-joint adapter was all I needed right in from the top. The wires were the toughest part to get off the plugs from all the heat. I would definately lube them up before you put them back on.

buy all AC De;co tuneup replacement plugs,wires, etc:

use anti seize on new plugs, be sure they are have proper gap

us dielectic grease on new wires, so they seat properly onplugs.

off brand parts can send your computer into orbit, not worth the trouble.

remember: cheapest is not always the less expensive in the long run.

VERY easy, just make sure you use anti seize compound on the threads of the new ones

should i get the delco wires, plugs and anti seize from the dealer or just order it from autozone

Already at 100K on an 05? Save your money on wires, not a common failure item on these engines. However, i would ohm them. I wouldnt replace them unless 1 is open. Open plugwires can still fire but the spark has to jump an extra gap.

Unless you are at 100,000 or have a problem then don't bother with plugs and wires. They are designed to go 100,000 before replacement.
I have 85,000 on my 03 suburban and have never touched the plugs or wires. Not planning to until 100,000 either.

I have a 2001 1500 ext. cab and i have never changed the spark plug wires out. It has 150,000 miles. Im guessing i should have changed the wires by now?

I was told, have not done it myself, but if you put the vehicle on jack stands and then remove the front wheels, you can remove the, I don't know what the official name is but it is the inner wheel well covering that is held by plastic type holders, you remove it and you can access the last spark plug a lot easier. Never tried it. just a suggestion.

At 57,000 miles, the "100,000 mile Iridium" Spark plugs on my 04 Silverado were getting ready to melt right off the side of the engine.So don't always believe the factory hype.
