I have the 4.3 L V6, and want to change the spark plugs. I doesn't look like I can reach them from the top, however. How does one reach the spark plugs on this engine to replace them? Do I have to remove accessoroies, reach up from below, or am I just not bending my arm hard enough?

 

Lift the splash guard inside the wheel well and go through there. There are plenty of threads posted concerning changing the plugs.
