I am having trouble changing spark plugs on a 2007 GMC Yukon XL 6.0L.
There is an aluminum heat shield that goes around the plug boot. It is difficult to get off & difficult to get back on. Is this even needed? The spring inside the heat shield is also confusing. Are there any tips about removal of this heat shield? It seems like it's supposed to snap back in but it doesn't.
Thanks for any help.
