For those who are changing alternator, it is not necessary to remove radiator as most DIY videos will instruct. It is a tight fit, but simply put cardboard protection against your radiator and you can wedge alternator up and out with no damage. It is a tight squeeze, but you can pull it out an put new one in without the extra wasted time pulling radiator out. I always look for short cuts on my vehicles when it comes to repairs.
