I did not see evidence of crack in radiator, but after I removed it from car, I noted coolant on bottom of radiator. Radiator has plastic side tanks, sometime fail. I had already previously replaced all of the hoses on the car, so I didn't think it could be anything else (heater radiator was not leaking)nm,. You could also smell the coolant when you got out of the car. OEM aftermarket radiator was about $150 (Nessens, I think was the brand name).
