Serpentine Belt Replacement
Today’s Weiler’s Garage article focuses on your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems. Let’s go over them. First, the serpentine belt drives your air conditioning system. Next, the belt powers the alternator. The serpentine belt may also run the pump for the power steering. And, on many vehicles, the serpentine belt powers the water pump (on some cars, the water pump is powered by the timing belt). Your Weiler’s Garage service technician can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon and will measure the amount of belt material to make sure there is enough. Drivers should be aware that there’s a special, spring loaded pulley attached to the engine called the tensioner pulley and sometimes an extra pulley call the idler pulley. Their job is to make sure there’s a constant tension on the serpentine belt so that it doesn’t slip. The spring can become worn and no longer provide the necessary pressure to keep the belt tight. That’s why it’s often recommended that the tensioner, and the idler pulley if so equipped, be replaced at the same time as the serpentine belt. All in all, the serpentine belt is an important part for the function of your vehicle. And it’s not that expensive to replace at Weiler’s Garage – so it’s good to do it before it fails.
