The drivebelts are found at the front of the engine. These belts do vital work in your car's components as well as the car itself. Over time, they can fail. Furthermore, they should be checked and adjusted periodically to avoid serious damage. Depending on the engine and accessories, there are different belt arrangements. For the 1998 and earlier models that have air-conditioning, there are three belts. For the 1999 and later four-cylinder engine, there are two belts. For the V6 engine, there are also two belts. You first want to make sure that the engine is off and the hood is open. You want to check the belts for cracks, separation, fraying and glazing. Also check the ribs for uniform depth. Belt tension is measured with about 20 pounds at the midpoint between pulleys. A set deflection is applied; for example, 1/2 inch when the distance is 12 inches between pulleys. Elevating the vehicle securely may be necessary for adjustments and tension can be altered by moving an idler wheel or components. To replace them, loosen the adjustment so you can remove the old belts. Ideally, you should replace all the belts at once. Make sure to identify each belt and its function so that you can put it back on correctly. When purchasing new belts, take the old ones for comparison. After installation, ensure that the new belts are properly positioned in the pulleys and centrally placed before heading out for ten minutes. After that, check the tension and adjust if needed.
