I have a rodeo with 83,000 miles which had a rattle from the engine on reving. problem was traced to a bad fan clutch, unfortunately the fan bracket broke the day I bought the replacement fan clutch from autozone. The autozone replacement fan clutch was smaller and doesn't seem like it fits like the original. It allows the fan to be further from the shroud and seems like it is noiser than the original fan. It definately seems louder than the original fan clutch. I am tempted to return the autozone fan clutch and get another as this one doesn't seem to work as stated in the literature that came with the replacement.(Stiff when cold and not noticablely stiffer when hot.)
I have replaced the water pump, timing belt and a idler pulley which was noisy. the engine runs great otherwise except for the loud roar at about
2000 rpm when shifting.Any ideas!!?
