Bad Bowtie Posted February 14, 2013 Report Share Posted February 14, 2013 Question? I'm going to be changing the spark plugs (for my mother) on my father's 2004 GMC Sierra C1500 V.H.O. It has the H.O. 6.0L, like the SS Silverado, & 110K on the clock. Seems like I read something in the past about adding anti-seize to the threads on the new spark plugs. I guess since the heads are aluminum?? Just thought I'd ask before my "project" begins this weekend. I'm removing the throttle body & cleaning it up good too. -Jon Quote Link to comment Share on other sites More sharing options...

The_aSSet Posted February 14, 2013 Report Share Posted February 14, 2013 Can't hurt, especially if you won't be changing them for awhile Quote Link to comment Share on other sites More sharing options...
desrtrat Posted February 14, 2013 Report Share Posted February 14, 2013 it's always good to put some on the plug threads. also put some dielectric grease inside the plug boots. you don't need a lot. what i do is use a small tube and put a thin line from the bottom to the top of the boot, than roll the boot between my fingers, and it will spread it evenly in the boot..if your changing wires, do it on the coil plugs also. makes life easier next time their removed.. good luck Quote Link to comment Share on other sites More sharing options...

patrick4317 Posted March 8, 2013 Report Share Posted March 8, 2013 Just be careful to keep it only on the threads. Quote Link to comment Share on other sites More sharing options...
