Reasons Why the Thermostat Fails to Open?

1 Answers

Reasons why the thermostat fails to open are as follows: 1. Internal damage to the thermostat, caused by excessively high temperatures for valve opening and full opening. 2. Damage to the thermostat's opening valve, due to prolonged warm-up time and low water temperature. 3. Blockage in the water passage, caused by debris or dust near the water passage. 4. Frozen radiator, primarily due to extremely low temperatures or the absence of antifreeze. 5. Water temperature too low, mainly caused by the detachment of the main valve or leakage of the oil controlling the main valve's movement. Solutions are as follows: 1. Inspect the thermostat internally. 2. Replace the opening valve. 3. Clear the water passage. 4. Defrost the radiator.

What Are the Causes of Low Engine Coolant Temperature?

Low engine coolant temperature is caused by a faulty thermostat or a constantly running cooling fan. The thermostat operates based on the engine's coolant temperature. If the thermostat malfunctions and the valve fails to close, the coolant will continuously circulate in the large loop, potentially causing the engine's temperature to drop too low. For electric fans, circuit faults can cause the fan to run continuously. For viscous (silicon oil) fans, a damaged viscous clutch can also lead to constant fan operation, both of which result in low coolant temperature. When the engine temperature is too low, the viscosity of the lubricating oil increases, leading to inadequate local lubrication, accelerated wear of components, and increased engine power consumption. Water vapor from combustion condenses into water and combines with acidic gases to form corrosive substances, intensifying erosion on engine parts. Unvaporized fuel due to low temperature washes away the oil film on friction surfaces and dilutes the engine oil, further accelerating component wear and causing faster degradation of oil performance.
