Review on ACDelco 38189 Professional Automatic Tensioner by Rick Harrison

Don`t waste your money on this inadequate product .When I tried this tensioner on my car belts it failed to work properly and caused a lot of issues. The supposed professional automatic feature was a complete joke, as it couldn't even keep the belt tight enough to function correctly. The inconvenience and frustration I experienced with this product was not worth the price. Save yourself the hassle and buy a higher quality tensioner from a more reputable brand..
