Coolant plays a vital role in keeping the vehicle from overheating, especially during the summer. It helps maintain the engine at an optimal temperature, ensuring smooth functioning. If coolant levels are low, the engine is more likely to overheat quickly, leading to serious issues such as a blown head gasket or mixing of engine oil and coolant. These problems can result in expensive repairs. Additionally, parts like the radiator and water pump may get corroded due to lack of coolant. In worst-case scenarios, running a car without coolant for too long can cause cracks in the engine block or cylinder head, leading to permanent engine damage. To avoid such situations, it’s essential to check coolant levels at least once a week and refill when necessary. Simple practices like parking in the shade, using sun visors, and keeping windows slightly open can also help reduce interior heat. These small precautions can make a big difference in keeping your car cool and protected during hot weather.
