100K service 4.8L Silverado

[emejay]

My 03 4.8L Silverado is approaching 100K miles and I'm wondering what I need to do. I have changed all fluids (trans , diff, coolant, engine oil) and was going to replace the spark plugs and plug wires, but couldn't pull the wire off the plug for fear I would rip it apart.

Any tips for plug and plug wire removal?

Any other items due for attention?

Thanks in advance for any feedback.

Sounds good, I'd give your belts a look to see how they're holding up.

[Nice rig]

If you plan on replacing the plugs AND wires, don't worry about ripping the wires if they are difficult to remove...give it a yank.

when you replace your plugs, put a little antiseze compound on the threads, and use some dielectric grease in both boots coil/plug. i found put a healty dab in the boot and roll it between your fingers, it will spread out evenly inside. so the next tine you have to pull plugs/wires it will be a snap.....
