Review on ⚙️ ACDelco Professional 38152 Drive Belt Tensioner Assembly: Ultimate Performance with Pulley by Craig Shah

Fixed my coolant leak. The only bad thing was the 90 degree plastic knee, but I had to order the whole unit to get what I needed. GM really made a mistake by making this knee out of plastic. Constant heat causes the knee to become brittle and break over time. Maybe the metal part will last much longer. The o-rings from the heater core hoses that fit this unit should be included with the new part, not the kit.
