If we see that the water or coolant temperature often exceeds 100☌, there could be problems and it would be advisable to have the car checked. If we have been stopped for a long time at very low revs it can be normal to notice an abnormal temperature.

For the coolant recirculation system to work optimally, the engine must be in full operation. However, it can rise after a long climb where the engine has been running a lot or if the engine has been running for a long time. The temperature of the coolant under normal driving conditions is between 80 and 90☌. What is the normal coolant temperature of the car's engine?Īlthough the coolant temperature gauge reaches 130☌, the temperature must be well below this threshold to be considered acceptable. It goes without saying that the oil gauge shows the typical oil sight glass with the drop and the sight glass is usually yellow. The coolant temperature gauge is very similar to the oil temperature gauge with which it is often confused. However, the temperature should not exceed 100☌ under normal driving conditions. The temperature gauge has a lever that indicates the temperature up to 130☌. The red coolant warning light is almost always on either inside the corresponding temperature gauge or in the center of the dash in the digital area.

How does the water temperature warning light work? A running engine that is not being cooled effectively will melt in a short time causing thousands of euros of damage. However, we must always remember that when the water temperature warning light is on, the only thing to do is to stop the car immediately and look for the problem. These technological improvements have certainly increased the performance of the coolant. Instead, increasing the boiling temperature of the coolant from 100° to 135° ensures greater heat removal even in the hottest months or with broken engines. In some Nordic countries where the cold reigns for several months of the year, the practice was in fact to mix animal fat with diesel fuel to prevent freezing. In this way, a car parked outdoors in winter will have no problems starting and running. With the lowering of the freezing temperature, the water-glycol coolant remains liquid up to -40° compared to only 0° for water. The advantages of this mixture are mainly the decrease of the freezing temperature and the increase of the boiling temperature. The most common of these coolant mixtures is water and glycol, almost always mixed in a 1:1 ratio (1 litre of water and 1 litre of glycol). However, over the years various fluid mixtures have been developed that are increasingly efficient in their ability to remove heat. In the early years of motorsport this fluid was simply ordinary tap water. It is no coincidence that coolant is often referred to as 'coolant'.

They indicate exactly the same thing, namely the temperature in degrees Celsius of the fluid responsible for cooling the engine.

There is actually no difference between these two warning lights. We often hear about water temperature sight glass and coolant sight glass and many people wonder what the difference is between the two. Water temperature warning light and coolant sight glass? Whatever you call it, it's important to know what it means and what to do when it's on or flashing. The more imaginative may also describe the water temperature warning light as a 'sailboat in the sea' or a 'buoy in the waves'. The red coolant sight glass is represented by a thermometer immersed in a liquid, symbolized as a wave.
