2005 Chevy Equinox.
Just wondering if there is an easy way to change the 3 rear
spark plugs.  Looks to be quite a pain.
Yes, they are a pain the ****. No special tricks. Best way is to lay over the engine  with the engine cover off, use an extension and a swivel. Wrists and forearms at  some odd angles, but you can get them. There is also a tool to "slave" the engine forward and hold it so you can get more room.
