Review on Gates 39162 Automatic Belt Tensioner by Sonny Flores

So it fits 08 Nissan Sentra but fitting is unrealistic. The only way to access the mounting screw is to loosen the left (facing into the engine bay) upper engine mount and lift the engine so you can access the screw after removing the wheel and fender liner from the passenger wheel arch. You'll need ratchet extensions, a breaker, and 45 or 50(?) bits of torque. Not for a feint of heart, and I nearly got dirty lifting the engine with a wooden block + jack under the already fragile oil pan. Youtube is indeed a double edged sword of knowledge. You'll need to lift about 3-4 inches to see the screw. Even if you do, grab a belt and maybe work on other parts like an alternator or supercharger if you're really ambitious.
