I have a '76 Datsun 280Z that my dad had given my for my birthday. Which he has had since 76. Well lets get on with my question. I got in an argument with my dad the other day, I told him that I had finally found out how to get my A/C belt off so I could get the fan (altinator) belt off. He told me that I "have to take it to a shop and have them do it. He said that if you change the belt it will throw off the timing in the car. I told him that it was not true but he subernally insisted that it was.
