  Q: How to operate the auxiliary drivebelt on Toyota Echo and Toyota Yaris?

  A: To install a Drive Belt, have a wrench, socket set, pry bar, and new belt on hand. Loosen the tensioner pulley, install a new belt using the correct diagram for routing, apply tension with the bar, and tighten the pulley. Check alignment and ensure the belt is seated properly on all pulleys.

  Q: How to inspect and maintain a drivebelt in a Toyota Yaris and Toyota Echo?

  A: A single auxiliary drivebelt is fitted at the right-hand side of the engine. The length of the drivebelt varies according to whether power steering or air conditioning is fitted. A manual tensioner is fitted, so the drivebelt tension should be checked at regular intervals and particularly after fitting a new drivebelt. Due to their function and material makeup, drivebelts are prone to failure after a long period of time, and should therefore be inspected regularly. The drivebelt is located very close to the right-hand side of the engine compartment, and better access can be gained by jacking up the right-hand front wheel and removing the engine right-hand lower cover panel. With the engine stopped, inspect the full length of the drivebelt for cracks and separation of the belt plies. Twist the belt between the pulleys to check its condition. Also check for fraying and glazing which gives the belt a shiny appearance. Check the pulleys for nicks, cracks, distortion, and corrosion. Small cracks in the belt ribs are not usually serious, but look closely to see whether the crack has extended into the belt plies. If the belt is in any way suspect or is known to have seen long service, renew it. Check the drivebelt tension by pressing on the belt at a point midway on the longest run between two pulleys. Compare the deflection noted with the figures quoted in the Specifications. If the drivebelt appears excessively taut or slack, adjust the belt tension. If the belt appears not to be too slack but has actually been slipping in service, check the belt for any sign of external contamination and cure the source of the leak before fitting a new belt.

  Q: How to remove the alternator drivebelt?

  A: Jack up the right front wheel and support the car. Remove the engine's lower cover panel. Loosen the alternator's pivot and lockbolt, unscrew the adjuster bolt, and push the alternator to release the drivebelt. Note the belt's routing as you remove it from the pulleys. For hydraulic power steering models, loosen the adjuster bolt and pivot bolt, then remove the belt from the pump and crankshaft pulleys. Refit the belt onto the pulleys, with the alternator pulley last. Loosen the adjuster bolt if needed to fit a new belt. Tighten the adjuster bolt to remove slack, then adjust the belt tension. Check tension by pressing on the belt. Repeat until satisfactory. Tighten the lockbolt and pivot bolt to the specified torque. Lower the car and check for slipping. If a new belt was fitted, recheck tension after a month or 1000 kilometers.
