I got my oil changed yesterday and when the guy had popped the hood, there was antifreeze spilled out, and he said there was a hairline crack on the radiator that will only get bigger. He said he would put in a new radiator, parts and labor, for 300 dollars. Anyone think that's too much or a good price? And is there any aftermarket radiator I can get that would perform better or a radiator from another acura or honda that would bolt up and work?
