What Causes Low Coolant in the Overflow Tank?
2 Answers
Low coolant in the overflow tank is caused by a radiator leak. Related information: 1. Introduction: The car radiator, also known as the heat exchanger, is the main component in the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release heat, and then returns to the water jacket to circulate, achieving temperature regulation. It is an integral part of the car engine. 2. Expansion: The radiator is a crucial component of water-cooled engines. As a key part of the cooling circuit in water-cooled engines, it absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, its temperature does not rise significantly after absorbing heat from the engine block. Therefore, the engine's heat is transferred through the liquid cooling circuit, using water as a heat carrier. The heat is then dissipated through large-area cooling fins via convection to maintain the engine's optimal operating temperature.
Let me share some insights on the issue of low coolant level in the overflow tank. The most common cause is leakage – aging hose connections may crack or the radiator itself might develop fractures, leading to dripping that's visible upon close inspection. High engine temperatures also accelerate coolant evaporation, especially after long summer drives. Worn water pump seals or a faulty radiator cap can cause slow leaks too. More seriously, internal leaks like a blown head gasket allow coolant to burn off, causing faster fluid depletion. I always remind myself to regularly check coolant levels and use proper antifreeze mixtures instead of tap water to prevent rust and clogging. Neglecting this risks severe engine overheating with costly repairs. Prevention beats cure – spending a few minutes monthly for checks and pre-trip inspections saves big on safety and repairs. Since adopting this habit, my vehicle's condition has significantly improved.
