What is the cold engine light really telling me?
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.
Is there a temperature below which the engine is cold?
There is a temperature below which the engine is cold, with the heater not working and the need to subject it only to gentle acceleration. There is a temperature at or above which the engine is overheating so badly that it must be shut down and the problem traced and corrected.
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?
Why does my car temperature keep going cold?
Here is a more detailed list of the most common causes when a temperature gauge stays on cold. The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself, sending the information to the cluster. Some cars have two temperature sensors, while other car models have one.

Why is my engine temperature reading so cold?
The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself which is sending the information to the cluster.
What should I do if my engine temperature light is on?
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. If the engine doesn’t appear to be hot though the light is on, it could be faulty sensor.
