Thermostat failure in the Suzuki Alto Lapin can be caused by a range of factors:

Wear and Tear: The thermostat is exposed to extreme temperatures and pressure, which can cause it to wear out over time. As it ages, it may fail to open o r close properly, leading to improper coolant flow.
Coolant Contamination: If the coolant is old, contaminated, o r not regularly changed, debris o r dirt can clog the thermostat, causing it to fail. Using the wrong type of coolant can also accelerate thermostat degradation.
Overheating: If the engine has experienced repeated overheating due to other issues like a coolant leak o r radiator failure, the thermostat may become stressed and eventually fail.
Corrosion: The thermostat housing and internal components can corrode if the vehicle uses old o r improperly maintained coolant. Corrosion can cause the thermostat to stick o r become blocked.
Manufacturing Defects: In rare cases, the thermostat may fail prematurely due to manufacturing defects o r poor-quality parts being used in the vehicle.
To prevent thermostat failure, it is important to perform regular maintenance on the cooling system, including flushing the coolant and replacing it as needed.
