Review on Gates DriveAlign 38158 Automatic Belt Tensioner by David Causillas

I bought this for GenIII GM 5.3L V8 engine. Installation was easy - just unscrew the three screws holding the old one to the block and reinstall. Some inlet pipes can get in the way, so remove them if necessary. My block is aluminum so I lubricated the bolts with blue Loctite to keep them from coming out. It appears identical to the original block that was on the engine - even the lines on the molding are the same.
