What does it mean when the temperature light is blue?
Low Engine Coolant Temperature
Low Engine Coolant Temperature If the warning light illuminates blue, it indicates that the coolant temperature is low. If the warning light illuminates red, it indicates that the coolant temperature is high.
Is it bad to drive with blue coolant light?
This BLUE illuminated light turns off when the engine is warmed up sufficiently. The blue light will stay on until the engine has reached optimal operational temperature. While you can still drive the vehicle safely with this light on, it is best to wait until the blue light has turned off.
Why does my temp light stay on?
This temperature warning light means that your engine is running at a temperature that is too high – in other words, your engine is overheating. However, a problem with the cooling system or low coolant can cause the engine to overheat, which leads to engine damage.
What do you do when your blue coolant light comes on?
The blue light sign is just a signal for you monitor your driving and keep calm till the coolant starts functioning again. If the problem sustains you should probably get to the nearest garage.
Why is my engine coolant light on?
The most common reason for the coolant light to become illuminated is simply that the coolant level is too low. There may be a floating sensor in your coolant tank that triggers the warning light when the level drops. Low coolant levels are usually caused by leaks, either in the reservoir or somewhere in the lines.
Why does the temperature warning light stay on while driving?
temperature warning light stays on while driving but coolant levels and engine temperature are fine Check that you have sufficient engine coolant in the reservoir. Check the V-belt / serpentine belt is present, not lose or damaged. Check the water pump is working. Check that the coolant system is clean and doesn’t require flushing.
What does a blue engine temperature warning light mean?
Having a blue engine temperature warning light appear on your dashboard shouldn’t concern you anywhere near as much as a red one. This simply means that your engine oil is not up to optimal efficiency due to the low temperature.
When does the coolant temperature warning light turn on?
The coolant temperature warning light turns on when your engine is sensed to be too hot and is at risk of damage from overheating. Is it safe to drive with the coolant temperature warning light on?
What is the cold engine light really telling me?
Engines run safely and effectively in a temperature range which is actually fairly narrow. The temperature gauge (or cold and hot indicator lights) typically measure the temperature of the engine coolant itself. When the car is first started, the engine is cold, and oil will need time to heat up and achieve good flow for lubrication.
