Hey guys/gals newbie here. I am always on the site and have learned a ton for everyone and I appreciate it. Just a couple questions I can’t seem to find.
I have a 2009 Tahoe Q4SS, I am doing a tune up, spark plugs, oil change. And I see the blue handle to drain the block, I know that’s usually done to winterize it but I’ve never done it before. Can I do that right before going to the lake this weekend? Also how is it done or what do I need to do? It has never been done before.
next question is does anyone know what this plug is behind the carburetor on the head? Right behind the throttle linkage.
thanks for any help
