What Happens When a Car Radiator Gets Clogged?
2 Answers
When a car radiator gets clogged, it can cause the car's temperature to rise. Introduction to Car Radiator: A car radiator generally refers to the radiator (automotive radiator) in the engine's water cooling system. The radiator consists of an inlet chamber, outlet chamber, main plate, and radiator core. The car radiator is part of the vehicle's cooling system. There are mainly two types: aluminum and copper, with the former used in general passenger vehicles and the latter in large commercial vehicles. How the Radiator Works: The coolant flows inside the radiator core, while air passes outside the radiator core. The hot coolant cools down by dissipating heat to the air, and the cold air heats up by absorbing the heat released by the coolant.
I've suffered from a clogged radiator before. Last summer while driving on the highway, the temperature gauge suddenly shot up to the red line, almost causing the car to overheat. A blocked radiator prevents coolant from circulating properly, trapping heat inside. When the engine overheats, it can lead to cylinder scoring or burned piston gaskets, costing thousands to repair. The main causes are usually scale or rust buildup, especially when using hard water or failing to change the coolant for long periods. Now I've developed a habit of flushing the cooling system every two years and checking if the coolant is cloudy or contaminated. Using professional antifreeze instead of tap water, mixed in the ratio specified in the manual, effectively prevents blockages. By the way, this issue also affects AC cooling efficiency—during summer, the air conditioning feels noticeably weaker. Regular maintenance has significantly improved my car's overall condition.
