Coolant fluid leaks due to thermostat failure often occur in the following locations:

Thermostat Housing: The thermostat is typically housed in a casing made of metal o r plastic, and the seals around this housing can deteriorate over time, causing coolant to leak. Cracks in the housing can also lead to fluid leaks.
Thermostat Gasket: The gasket that seals the thermostat to the engine block may wear out o r get damaged, leading to small o r significant coolant leaks around the thermostat area.
Radiator Hoses: The hoses connected to the thermostat housing o r the radiator may also develop leaks if they are brittle o r cracked due to old age o r overheating caused by thermostat failure.
Coolant Reservoir: In some cases, a malfunctioning thermostat can cause the coolant to overheat and overflow from the coolant reservoir, which may be mistaken for a thermostat-related leak.
Solution:

Inspect the thermostat housing and gasket for signs of wear o r cracks.
Check the radiator hoses and coolant reservoir for any visible leaks.
If leaks are found, repair o r replace the affected components as soon as possible to avoid engine damage.
