 What does Engine Temperature Warning Light mean?

1. The Engine Temperature Warning Light indicates an overheating of the engine. It simply lets us know that our vehicle has been in use for a longer time than it should be.
2. It also gets switched on if there is a lack of cooling water or a faulty cooling system. When the coolant is not of high quality, it causes a blockage during cold weather where the temperature drops below the freezing point.
3. Sometimes, a small leak in the system lets air enter into it taking the shape of a bubble. The coolant cannot push through the bubble to reach the engine causing the radiator to lose coolant, thus turning the warning light on.
4. A low level of oil is another reason for building up excessive heat.
5. Another reason for a temperature warning light might be a broken thermostat.
6. Sometimes, it might be due to the presence of a foreign object or mineral deposit, which blocks the flow of liquid through the radiator to disperse heat.
7. We must keep in mind that this light gets turned on and the engine must not start heating up even if the cooling system is in good condition.
