Nah, your engine looks fine. Mine is the scary looking one. Thats a pretty scruffy looking radiator though. I think it's time for a replacement. Did I mention flush the system while you have it apart? Your hoses don't look to bad. If your dad can change the oil he should be fine flushing the system and putting a new radiator in. That's a nice looking Mav. Wish mine looked that good.
Get a fan belt and leave the radiator cap loose so it cant build up any pressure. That should hold you untill you can get a new radiator.
Fan belt.. that's a good question.............I must have had one before.. could it have fallen off? Aww geez, I wish I would have taken Auto Mechanics in school.
