it could cause a problem if the tubing inside is bent or kinked, but its possible its ok depending on how bad its bent up. If it doesnt leak, it could still be bent up enough inside to restrict flow and long story short, then ur probably gonna be lookin into like a b16 swap lol Replacing a radiator is not a big job, and if u do ur own work then u could easily make out with a good deal on the car, but i dont know much about hondas and pricing of them so ill leave it to someone else to make that call. Either way its ur own decision iif u feel the car is worth it.
