Review on ACDelco 12663047 Original Equipment Tensioner by Ryan Pollock

Other GM engines - this one matches a 2007 Saturn Aura Greenline engine - a bad hybrid that should never have been built! To install it on this car it was necessary to remove the headlight housing to make room - still a tight fit. We removed the steel compression plate on the spring after installation. That distance was pretty dangerous - beware of the flying steel. The item comes without instructions. Appears to be of good quality. The part does not include the 2 bolts that attach it to the engine block.
