The good news is that if this is the reason for the light turning on, it’s unlikely that there are any actual mechanical issues. This is why keeping the engine running for extended periods without moving can activate the temperature light. Without enough cool air entering the radiator, fluids overheat quicker, preventing them from doing their job. Most causes for the engine temperature light on the dashboard turning on pertain to an issue with the cooling system. What are the Common Reasons for the Engine Temperature Warning Light Will Come On? This can provide useful details for your mechanic to work with later on. Modern cars will also save a diagnostic file that contains information about the event. If any component detects a problem, a signal will be sent to the onboard computer. This includes a type of thermometer that measures temperatures, as well as a tool for measuring coolant levels. Your engine contains a number of measurement tools designed to keep track of the functionality of key components. Keep in mind that this is separate from the oil temperature gauge. Under normal driving conditions, the temperature shouldn’t exceed 100 degrees Celsius. You can use the temperature gauge as a useful guide to determine whether the system is too hot. The engine temperature light car warning is almost always located on either side of the temperature gauge in your instrument cluster. How Does the Engine Temperature Warning Light Work? If you find that the problem is low fluid levels, you can safely refill the container with water so that you can head to a service centre for a more thorough check-up. It’s important to be careful when checking the coolant as the steam can burn you if it’s still too hot. Once the engine is cool enough, you can use a rag or glove to remove the radiator cap, which pressurises the system to prevent the liquids within from boiling. Then shut down the engine and let your vehicle cool down for 20 to 30 minutes before inspecting anything. If you’re driving when the light turns on, aim to pull over as soon as you safely can. Engine temperature warning light bulbs will start flashing red when the coolant is failing to move through the system and keep the engine running smoothly. This liquid circulates throughout the engine system to maintain safe operating temperatures. Your engine is kept cool by a mixture of water and ethylene glycol known as coolant or antifreeze. What Does it Mean if the Engine Temperature Warning Light is Flashing? The purpose of this is to indicate that there is either a coolant fault or the engine is too hot. When there is an issue with your coolant, the warning light will illuminate red or sometimes yellow. Depending on the make and model of your vehicle, there can also be a symbol written as “TEMP” or “ENGINE OVERHEATING.” The engine temperature warning light or engine overheating light is typically represented by a thermometer submerged in two flowing waves. What is the Engine Temperature Warning Light? There can also be mechanical damage to one of the coolant system components. For example, fluid levels might be low due to an opening in the container through which liquids are constantly leaking out. However, the problem can extend to other components. In most cases, the issue is related to coolant temperature or fluid levels. If it remains on, it’s because the computer has detected a problem in the system. This is only to verify that the bulb is working. Whenever you start your vehicle, the engine temperature light will illuminate for a couple of seconds. Why is my Engine Temperature Warning Light On?
