Service Center > Under-Car Repair > Drive Belt Tensioner Service
The drive belt on your Subaru is recommended to be replaced at your major service interval, but your Subaru's tensioner should only be replaced when needed. Make an appointment with Mike Shaw Subaru in Thornton, Colorado today to have your Subaru's drive belt tensioner inspected to ensure it is not in need of replacement. If your Subaru should need a new drive belt tensioner we will first loosen the drive belt tensioner and remove the old belt. Our Subaru Service Technicians will then inspect the tensioner and idler pulley bearings for noise or signs of wear. We will then install a new belt and tensioner to factory specifications, and check the belt tension and make final adjustments as necessary.
Drive Belt Tensioner Service Significance
The drive belt tensioner controls the accessory drive belt on your vehicle. The tensioner and belts in turn affect many systems, including power steering, the alternator, air conditioning, and sometimes the water pump, engine cooling fan, and emission control. You can lose one or more systems if the tensioner and belts aren't working properly. This can result in sever overheating, loss of power steering, loss of electrical power, and even engine failure. Replacing the tensioner saves you money by avoiding costly engine damage and repairs. Have your drive belts and tensioner inspected and replaced as your vehicle's manual recommends.
