Function and importance

• Temperature Regulation: The thermostat's primary role is to maintain the engine's optimal operating temperature, typically between 195 to 220°F (90 to 104°C).
• Coolant Flow Control: It acts as a valve, regulating the flow of coolant between the engine and the radiator.
• Engine Performance: A correctly functioning thermostat is essential for efficient engine operation, preventing both overheating and overcooling.

Why thermostats fail

• Age: Over time, the materials within the thermostat can degrade, leading to malfunctions.
• Defects: Manufacturing flaws can cause premature failure.
• Overheating: Repeated overheating can stress the thermostat, leading to failure.
• Sludge Buildup: Contaminated coolant or engine sludge can impede the thermostat's movement, affecting its performance

Common symptoms of a bad thermostat

• Temperature Fluctuations: The temperature gauge on your dashboard may show erratic readings.
• Engine Overheating: The temperature gauge stays consistently high, indicating the thermostat is stuck closed, preventing proper coolant flow to the radiator.
• Engine Overcooling: The engine never reaches its optimal operating temperature, which can happen if the thermostat gets stuck open.
• Poor Fuel Efficiency: If the engine runs too cold due to a stuck open thermostat, the engine runs rich, leading to decreased fuel economy.
• Heater Issues: The vehicle's heater may not blow warm air or take an extended period to warm up.
• Coolant Leaks: A rusted or corroded thermostat housing can lead to coolant leaks or puddles on the ground
