  Q: How to remove and refit an alternator in a Toyota Yaris and Toyota Echo?

  A: Loosen the clamp nut and detach the earth lead from the battery negative terminal post. Remove the Drive Belt. Jack up the front of the car and support it on axle stands. Disconnect the main wiring plug and undo the nut securing the battery supply cable. Lift off the supply cable and place it to one side. Support the alternator and remove the upper adjuster lockbolt and lower pivot bolt. Remove the alternator from its mounting lugs on the engine. Manoeuvre the alternator out of the engine compartment. Refitting is a reversal of removal, ensuring that the pivot and lockbolts are hand-tight to begin with. Reconnect the wiring correctly and tighten the retaining nuts. Refit and tension the auxiliary drivebelt.

  Q: What is the recommended action if there is suspicion of a faulty alternator?

  A: If the starter motor and Alternator is faulty, take it out of the car and have it tested by an auto-electrician. These professionals can also provide and install new brushes at a reasonable price. Inquire about the repair costs beforehand, as it might be more cost-effective to acquire a new or exchange motor instead.
