Review on ACDelco ACK070763 Professional Accessory Tensioner by Elton Luo

Attempted to install them on a 2002 Camry (4 cylinder). The center pulley mount had a pair of protrusions that limited the rotation of the hydraulic cylinder. The original didn't have them, which allowed the cylinder to rotate more. This proved crucial for the installation of the device. There's very little room to try and tamper with this in place and while removing the old one wasn't difficult (after raising the engine), this one wasn't an option. I had to remove the cylinder from the pulley. bracket and then install each part separately. At least it worked. The V-belt fit, but was pulled tight. Good quality parts for the price but sometimes you pay for it in other ways.
