The most common causes of radiator leaks in a Prius include:

Corrosion: Over time, coolant can react with the metal parts of the radiator, leading to corrosion, especially if the coolant isnt changed regularly.
Worn-out seals: The seals around the radiator o r hoses can degrade with age, allowing coolant to escape.
Cracked hoses: Flexible hoses can wear down and crack due to exposure to heat and pressure, leading to leaks.
Debris damage: Rocks, road debris, o r accidents can cause physical damage to the radiator, leading to leaks.

To prevent these issues, it’s essential to maintain regular coolant flushes, replace worn hoses, and ensure the radiator is shielded from physical damage.
