  Q: How to inspect the alternator/air conditioning compressor and power steering pump drivebelts in Toyota Sienna?

  A: For 2006 and earlier models, the alternator/AC compressor and power steering pump drivebelts are on the engine's right end. These should be regularly checked for wear and tension. The cars have two belts, one for the alternator and AC compressor, and another for the power steering pump. To check, open the hood and inspect each belt visually and by touch. If worn, replace the belt. Use a belt tension gauge or rule of thumb to check tension. If adjustment is needed, loosen the bolts and adjust. To replace, follow the adjustment procedures and remove the old belt from the crankshaft pulley. It's advised to replace both belts simultaneously. For 2007 and later models, there's one automatically tensioned belt. The checks are the same as earlier models. To replace, loosen the right front wheel's lug nuts, raise the car and remove the wheel. Remove the inner fender splash shield to access the tensioner pulley. Loosen the pulley, remove the old belt, and install the new one as per the underhood routing diagram sticker.
