5 Signs Your Volkswagen Thermostat is Failing in Charleston To maintain the temperature of the engine at optimum level and to prevent it from overheating, every model of Volkswagen has a well-defined mechanism known as a thermostat that can allow the engine to consume the fuel efficiently. Moreover, it is operated on the principle of expansion and contraction under the influence of temperature. Subsequently, it has a structural element called a sealed container that is filled with a substance and very sensitive to heating and cooling. Like other components of the Volkswagen, the thermostat is also damaged for several reasons. When it happens, try to diagnose the problem immediately before it is too late.
The main purpose of the thermostat In general, the thermostat is a complex part of the Volkswagen that is switching the fluid movement of the engine from a small circle to a large one and vice versa. Thus, the thermostat has a valve that remains closed when the antifreeze is circulating within a small circle and allows the fluid to enter into the large circle. On the other hand, the valve opens completely at high engine loads, but at the lower engine loads, it only flows the required amount of antifreeze onto the large circle. To ensure a safe and reliable operation of the engine in different modes, the thermostat is highly sensitive to normal temperature changes.
Signs of a failed thermostat When the thermostat of your Volkswagen is failed, you will notice several signs while driving it on the road. The following points define the signs more briefly.
Erratic temperature gauge Generally, the erratic temperature gauge is a common sign of failed thermostat in the car. When it is failed, keep a close eye on the temperature gauge of the dashboard for preventing the engine from overheating. Due to the failed thermostat, the temperature of the engine is changing erratically and releases too much coolant. All we know is that the failed thermostat will ups and down the temperature of the engine and affect its performance poorly. When the engine is cold and hot, it will run not run very efficiently and cause major breakdowns in the engine.
Engine overheating
Like the other signs, the engine overheating is also a fatal consequence of a bad thermostat in Volkswagen. The main purpose of the thermostat in your car is to control the heat of the engine when it is reaching its normal operating temperature. Due to the failed thermostat, the coolant is unable to flow into the engine and overheat the engine. If you are driving your car with a bad thermostat, then it will damage the parts of the engine in the long run. So, don't drive the car for longer when the thermostat is failing entirely.
Unusual noises If you are hearing strange sounds from the engine, then don't forget to check the thermostat as soon as possible. When the coolant is boiling and the thermostat is stuck open, you will hear rumbling sounds from the engine and radiator. On the other hand, a small problem within the cooling system also produces knocking and gurgling sounds from the engine. So, when you will hear such unusual noises from the engine or experience any other symptoms inspect the cooling system for diagnosing the real causes behind noises and replace the thermostat immediately.
Coolant leaks When your car has a coolant leak, take it to a reputed mechanic for replacing the thermostat. Moreover, the thermostat housing builds a coolant leak when the starter is stuck in the closed position. Many times, the leaks cannot be found on the garage floor because they may be subtle. But, when the thermostat housing is corroded or damaged entirely, you will notice the coolant leaks on the garage floor. However, it clearly indicates the thermostat needs immediate replacement by a professional mechanic.
Malfunctioned heater The engine is overheated when the thermostat is stuck in an open position because the hot air is not blowing through the vents. For running the engine smoothly, the coolant will flow into the engine and overheat after normal engine operations. Every car has a heater that will be turned on for providing cooling air from the HVAC constantly by opening the thermostat. But, when the heater is malfunctioning, the engine is getting too cold instead of hot. At this point, you have to inspect the car from the reputed auto repair shop.
Conclusion
For preventing the failed thermostat in the Volkswagen, you have to check the thermostat regularly. Try to collect little knowledge about all the components of a car to save your money on big repairs. Subsequently, check the coolant frequently to function all the components of the cooling system. People living near Charleston can fix the failed thermostat of the Volkswagen at an affordable price by consulting with a reputed local mechanic.
