What causes bottom of radiator to blow out in 1993 Geo storm with 1.6 liter engine?

The bottom of the radiator in a 1993 Geo Storm with a 1.6-liter engine may blow out due to several factors, primarily related to overheating or excessive pressure in the cooling system. Common causes include a failing thermostat, a malfunctioning water pump, or a clogged radiator that prevents proper coolant flow. Additionally, weak or corroded radiator materials can lead to structural failure. Regular maintenance and monitoring of the cooling system can help prevent such issues.
