Mga fellow tsikoteers, pa-help naman.

Corolla xl 1997 ang ride ko... from sm rosario going to imus, at kapa-park ko lng ng oto sa bahay namin, biglang lumabas sa ilalim yung maraming tubig na greenish yellow, sabay umusok na, at namatay na ang makina. After several hours, binuksan ko yung hood and I found a heavily cracked radiator (around 3 inches). Can this still be repaired? Was it caused by the non-funvtioning fan?

Thanks...
