In general, the thermostat is an important part of the cooling system which is responsible for controlling the coolant flow in the engine. To function the engine properly, the thermostat needs to be run in perfect conditions. Moreover, it can allow the engine to maintain its temperature and ensure that the engine will reach its normal operating temperature.
Due to any reason, if the thermostat of the Jaguar is failed, then it will cause a serious problem and affect the engine performance. Neglecting the bad thermostat in your car can eventually damage the engine which is the costliest part to repair. Always consult with a reputed mechanic for changing the bad thermostat in your Jaguar.
What are the functions of the thermostat?
The thermostat controls the flow of hot coolant through the radiator and adjusts the coolant flow towards the radiator. Thus, the thermostat is consists of two phases such as closed or opened conditions. If the engine is idling, then the thermostat is closed as it is relatively cold. When the engine starts, the temperature of the engine and coolant is rising.
Moreover, the open thermostat will allow the coolant to flow into the radiator to cool down the engine and return to the coolant chamber inside the engine. This mechanism makes sure that the engine operates at the ideal temperature and prevents engine overheating problems. The thermostat needs to close and open at the right time for preventing serious engine problems.
Signs of a bad thermostat
When the thermostat of the Jaguar is failed, then it will show numerous signs while driving on the road. The following points define the signs more briefly:
Engine overheating
If the thermostat of the Jaguar is failed, then the engine is overheated and causes several fatal consequences. When the temperature of the engine is reaching its normal operating temperature, then the thermostat is allowing the engine to control the heat. If the thermostat is failed, then the coolant is unable to flow into the engine and causes the engine to overheat.
If you are driving your car with a bad thermostat, then it will damage the engine in the long run. Due to these reasons, you have to keep a close eye on the signs of a bad thermostat in the car to avoid major engine repairs during a drive.
High-temperature reading
Generally, the engine of the car is overheated for many reasons such as the leak in the cooling system, malfunctioned thermostat, blocked cooling system, and many more problems. Thus, the thermostat is opening and closing at the right time for allowing the right amount of coolant into the engine.
If the thermostat is failed, then it is blocked in the closed position and causes the engine to overheat. Throughout the process, the coolant flow to the engine is disrupted. Due to the failed thermostat, the temperature gauges are showing an unusually high reading.
Leakages and steam from the engine
When the thermostat of the car is not operating efficiently, then the coolants of the engine is going too hot in the coolant chamber and find a way to escape. As a result, you will notice too high pressure in the engine. Throughout the process, the hot air is rising and the boiled water will form steam when it heats up.
When the coolant heats up, the coolant pressure gets too high and causes a leak. At this point, the coolant is often pressed out of the radiator tank. Thus, the coolant leaks are very easy to detect and produce white steam smoke from the engine.
Rising engine temperature and full expansion tank
When the thermostat remains closed, then the coolant doesn’t escape to the radiator. During normal engine operations, the coolant inside the engine heats up and converts into steam. During this process, the coolant inside the radiator remains unchanged.
If you found that the temperature of the gauge is rising with a filled radiator tank, then it is likely to have a problem with the thermostat. Moreover, the rising coolant level in the engine also indicates that the engine begins to overheat.
Poor engine performance with noises
Like the other symptoms, the bad thermostat will also affect the performance of the engine because the engine is running at a certain temperature and lies between 90°C to 104°C. In fact, the failed thermostat will degrade the engine performance and lower down the engine temperature.
When the thermostat is stuck open, you will start to hear rumbling noises from the car. However, the noises are produced from the car either from the engine, radiator, or both. Thus, the noise produced from the car is feeling like a gurgling or knocking sound. Therefore, when you hear such noises from the car, it most probably has a bad thermostat.
Things to consider when the thermostat is failed
If the thermostat of the Jaguar is failed or not working properly, then there are several things you have to consider:
· At this point, check out the thermostat regularly in your car. Get some knowledge about the thermostat for major engine repairs.
· Throughout the service and maintenance, you have to understand and check the temperature indicator of the car.
· In this process, check out the coolant frequently and never use water as a coolant.
If you are currently living in Charleston and found any of the symptoms in your Jaguar, then consult with a reputed mechanic for diagnosing and fixing the bad thermostat efficiently.
