When the engine is turned off and pressure in the system goes down, the coolant is then transferred back into the radiator. The reservoir is there to store hot coolant when your engine is operational and pressure is high within your cooling system. These are the three things you should check: Now that you’ve confirmed that there’s an external leak, now it’s time to identify where the leak is coming from. Keep in mind that there are red coolants as well, so be sure to check what coolant your car has been using. Coolants are usually green in color, so if you see a puddle of green fluid underneath your car, then you have an external coolant leak. Afterward, wait for 15 minutes and see if there’s a puddle of coolant underneath your car. After driving your car, park and turn off your car. It should be quite easy to check if your car has an external leak. This is how you check for a coolant leak: 1. If this is the case, then you will need to identify where the leak is happening. Afterward, if you notice the temperature rises again and the coolant level is already low again, then there’s a leak in your cooling system. Once you refill it, try running the car again. If the coolant comes premixed, then you won’t need to mix it with water. Keep in mind that some coolant comes premixed, so be sure to check it before you refill it. If the coolant level is low, refill it with a 50-50 mixture of coolant and water. Instead, your problem may lie with either the water pump or the thermostat, but we will discuss this further later. If it does, then you don’t have a coolant leak. Once your car has cooled down, open the reservoir cap and see if the coolant inside the tank reaches the ‘Maximum’ indicator. To do this, locate your car’s coolant reservoir tank, which is a plastic container with a cap on top. If your engine is overheating, then we recommend checking your coolant level first to determine the problem. If you want to learn more about how your vehicle’s cooling system works, watch the video below: Over time, this will cause severe and very expensive damage to your engine. If you continue to drive, your engine will overheat and break down the components inside. At this point, you should pull over and stop driving since there’s not enough coolant to extract the heat from your engine components. When this happens, you will see your temperature gauge rise above 240☏. Without coolant, your car won’t be able to cool the engine as nothing will extract the heat. Most cars will operate with their coolant temperature (shown by the temperature gauge on your dashboard) between 180☏ to 240☏. The coolant will carry the heat away from various engine components and keep it at its optimal operating temperature. Running a car without sufficient coolant can lead to severe and expensive damage to your engine.Ī coolant works by circulating through your engine and extracting heat. This is often caused by a coolant leak in your car’s cooling system, which you will need to address immediately. More often than not, the problem stems from a lack of coolant. If you’re driving along and notice your engine’s temperature is rising, then you have an engine cooling issue.
