Low coolant engine overheating9/2/2023 ![]() ![]() Why would a car overheat if it has coolant?Īs we indicated earlier, one of the primary causes for engine overheating is low coolant level. With so many components making up the cooling system, there is a very high chance that any of the mentioned components can go bad and cause significant issues in the cooling process resulting in engine overheating. That's when the coolant goes back to the radiator and drops its temperature, so it's ready to run around the engine again and cool down. In other words, as the coolant runs around the engine, its temperature increases gradually until it gets to a point where it can't drop the engine temperature anymore. It is responsible for cooling the coolant temperature down once it comes back hot from the engine. The radiator is a core component in any vehicle's cooling system. These hoses are designed from a specific material that withstands hot coolant as it comes back extremely hot from the engine temperature. The hosesĬoolant leads certain hoses to run through to reach the engine at the right time we need it. Hence, the thermostat allows the coolant to run through the valve and bring the engine temperature down. Therefore, the thermostat receives a certain signal from your vehicle's computer telling it that the engine temperature exceeded the maximum threshold. In other words, the coolant does not run continuously around the engine when the engine temperature is not high. The thermostat works like a monitor or a valve responsible for allowing the coolant to run around the engine when needed. Therefore, it might be slower than it should, which could lead to significant engine overheating issues. Without a perfectly working water pump, coolant will not have the right pressure level. The water pump is responsible for pumping coolant with a certain pressure to run around the engine at the right speed, so your engine temperature cools down. The coolantĬoolant is the primary fluid in your car responsible for running around the engine as its temperature gets higher than a maximum threshold. The cooling system is the primary system that consists of the following components: 1. Luckily, your vehicle is equipped with several components and systems that work together to drop the engine’s temperature to where it should be. When the engine's temperature exceeds the maximum point, other systems require some help to bring its temperature to the operable level. In any vehicle equipped with a combustion engine, it produces a lot of energy and heat, causing its temperature to exceed maximum thresholds. This way, you'll get an idea about what could go wrong that could cause your engine to overheat other than the low coolant. ![]() How does the cooling system work in your vehicle?īefore we dive into the details about “why would a car overheat if it has coolant?” First, we must understand how the cooling process works in your vehicle. ![]() This article walks you through all potential culprits that might cause engine overheating and highlights their expected repair costs along with symptoms of bad parts that helps you detect the problem early to save on repair costs. Learning about all other reasons for engine overheating besides the low coolant is critical for every driver. When the engine temperature exceeds the maximum threshold, there is a very high chance that you might end up with a completely damaged engine.Īlthough low coolant is the primary cause for engine overheating in many vehicles, other possible culprits might cause your vehicle to overheat even if it has sufficient coolant. Engine overheating is one of the worst enemies that might face your vehicle. ![]()
