i read that for chevy trucks, the bank 1 cylinders are uniquely on your right as you face engine from bumper - driver side.
the 6.0L V8 is tight and you are reaching way down past valve cover near spark plug of cyl 1 and exhaust manifold. i cannot see it well, but there is a spark-plug-like thing with wires insulated in what martha tells me is a shiny foil-like insulation. this wire goes into a bigger sheathed cable of wires, which seems odd. i think this is HO2S in question - bank1,sensor1. but where is it's harness plug-in?
from underneath, i can clearly see the bank1,sensor2 O2 sensor. its wires are sheathed in common black plastic insulation and go 12" to the harness connection.
i may use the slot socket, but 1st i might need a chevy owner of a 2005 vintage to explain what i am seeing/feeling.
In automotive terms, the right side as you face it is the left side - drivers side. Cylinder #1 is the front, left cylinder so that's bank 1. It's an industry standard so we can have these discussions without confusion :-)
You might have better luck looking up from underneath. I have an '07 Avalanche. It has a 5.3 (07 was the last year you could get a 6.0 but it doesn't have it). I can't imagine its much different. I can clearly see all 4 sensors from underneath. I've had to change 2 of them, both post cat tho.
