Question about 2004 GMC Yukon
Hi, I have a 2003 GMC Yukon and I'm trying to change the spark plugs. The spark plugs have some kind of metal tube over them that comes out when I pull off the spark plug wire. What are the metal covers? Do I need to put them back on? If so, how do I get them back in? Also, they have a small spring on the end facing the engine. Thanks, Jeff

There is a GM special tool for removing these heat shields, without the tool you will destry the plug boot getting them off.

The "method" for removing the plug wires and heat shield from a 2003 Yukon is a half turn to the right and then again to the left. This will "release" the plug wire and they should then pull free like any other wire. "special tools" are for special tools. Replace these wires in the same manner in which they came off. Attach and then gently press as you turn them half a turn left and then half a turn right.
