Hi there. Depending on whether the mechanic has the right tools, supplies and experience, replacing an alternator can take as little as two hours or as much as 4 to 5 hours. Generally speaking though, it’s a three hour job. You can request an estimate to have one of our mobile mechanics complete the alternator on your Lexus if you’d like.
