How does a leaking radiator affect the Prius hybrid system?

The Prius has both an engine cooling system and an inverter cooling system. If the radiator leaks, how does it impact the hybrid battery and inverter performance?

The Prius has separate cooling systems for the engine and the inverter. A radiator leak affects both:

Engine Overheating: Low coolant levels can lead to engine overheating, which may cause warning lights and significant engine damage.
Inverter Overheating: The inverter also has its own cooling system that relies on coolant. A radiator leak can reduce coolant flow, leading to overheating of the hybrid system, potentially affecting hybrid battery performance and efficiency.
