What does coolant temperature too high mean?
overheating
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.
Why does my coolant temp go up and down?
The primary reason your car temperature gauge goes up and down while driving is simply because a component in your cooling system is not functioning correctly. This could be the thermostat valve, radiator hoses, radiator fan, the temperature gauge, or the coolant itself that circulates around cools off the engine.
What causes high engine temperature?
There are a variety of reasons that a vehicle can overheat, such as cooling system leaks, blocked hoses from corrosion and mineral deposits, radiator issues or broken water pumps. Regular inspections may help avoid overheating issues down the road. Come in today for a consultation on your coolant/antifreeze fluid.
Why is my temp gauge high?
If the temperature gauge reads high, it could mean your engine is overheating. Another reason your reading might be high is you could be losing coolant. A small leak or evaporation may cause your radiator to slowly lose coolant. A third reason your temperature gauge reads high could be because the thermostat is broken.
What happens if you overfill the coolant reservoir?
When you overfill the coolant reservoir, there won’t be much space left for the heated coolant to expand. As a result of which, the pressure inside the reservoir would increase gradually. When this happens, the cap of the tank will open, and the hot coolant would pop out like a puddle of lava.
