CAUSES OF ENGINE OVERHEATING IN CARS It must be annoying when you are driving to catch an urgent meeting but suddenly steam starts spewing from under the hood, and you have to pull over somewhere.These are something that may lead to overheating. 1. A Leak In The Cooling System The air that enters the system through the leak is one of the possible causes of engine overheating. The coolant drips through the puncture, creating space for air to get sucked in. The air takes the shape of a big bubble, known as an airlock, and occupies the top part of the system. The coolant can’t push through it to reach the engine, causing the overheating. 2. Condensed Coolant It’s an annoying problem in cold weather, especially in those places where temperature drop below the freezing point. If the coolant is not high-quality, it can get concentrated and cause a blockage. Such a condition will result in engine overheating and damage the radiator. 3. Blockage To Coolant Circulation It can bring about the same symptoms of the gelled coolant. Sometimes, a defected thermostat, mineral deposit, or a foreign object can block the liquid from flowing through the radiator to disperse heat. 4. Low Level Of Oil Engine oil itself helps with the cooling process and prevents the buildup of excessive heat. In fact, the oil removes 75% to 80% of the unused heat in the engine. It also keeps various parts properly lubricated, reducing friction and the subsequent overheating. 5. Broken-Down Water Pump It’s one of the most frequent reasons for engine overheating. It is a component that actively takes part in maintaining coolant circulation. It can wear out or break over time, leading to the damage of the impeller that does not turn anymore. #nairaautoparts#nigeria#lagosnigeria#abuja#fct#coolant#cars#carengine
