Q: Radiator leaking from crack in top

asked by on

I have a four inch crack in the top of the radiator, causing the car to leak. The radiator top is metal.

This is pretty common. The metal gets very thin from cooling system wear, and the tank cannot hold the pressure any more and splits. I recommend replacing the radiator and testing the complete system for any other problems.
