Can anyone get some service information about changing the spark plugs? What is the factory gap, what plugs, and how to access the passenger side plugs since the Hybrid componants are right above them?
I am assuming the fender liner might allow some access, but the frame rail is right there too.

 

AC Spark Plug 41-110
[Platinum Spark Plug]; .040 GAP

The ones on the passenger side are tough. No good way to get at them even through fender with wheel off.

 

Thank you,
I guess GM still hasn't found a decent way to access spark plugs (last GM I worked on was a '00 Buick Regal).
