Still technically the wrong section as it is not a "V" car
- (optional), remove Strut Tower Brace (some need it to remove the engine cover and it does help as it's one less thing to work around)
- Remove engine cover
- Remove any cam cover ignition coil shield or fuel injector shields
- Personally on LD8 and LH2 N*'s, I find it easiest to disconnect the main ignition feed to the coils, then unbolt the whole "cartridge" (as GM calls it), which leaves the coils mounted to an aluminum bracket, and remove it all as one piece carefully. Remember the coil module assembly sticks down to the holes, so there will be some length to them. There are also little green rubber doughnuts that fill the gap between that aluminum bracket and the actual cam cover to help seal the hole from any grease/debris. Make sure not to lose these.
- Remove plugs down in their respective holes.
On the passenger side you may have to work around A/C lines and on the drivers side, I've found on these STS's to completely remove and relocate the coolant overflow tank (you will need to have a long extension to get down behind the tanks and to the nut that holds it to the car.
