What kind of stock radiator came in my 89 v-8 automatic with air 305 engine? I am just getting it out of storage and noticed a hairline crack on the plastic rib. Is this fixable or do I need to get a new one? How hard to install one?

 

A competent radiator shop can replace your side tank for a reasonable fee. I would recommend replacing both side at the same time - if one side is cracked, the other isn't far behind. I recently replaced both of my side tanks. I think they were around $20 a piece for parts. I don't know about labor as I replaced them myself at my shop.
