Why doeS my coolant overflow and engine overheat?

Coolant overflow and engine overheating can occur due to several reasons, such as a malfunctioning thermostat that prevents proper coolant circulation, a failing water pump that doesn't circulate coolant effectively, or a radiator blockage that impairs heat dissipation. Additionally, a leak in the cooling system can lead to low coolant levels, causing the engine to overheat. It's essential to diagnose the issue promptly to prevent potential engine damage. Regular maintenance and checks can help avoid these problems.
