Why Coolant Leaking from Engine?
Understanding the Basics of Engine Cooling Systems
The engine cooling system is a vital component of a vehicle’s engine, responsible for maintaining the optimal operating temperature of the engine. It consists of a series of tubes, hoses, and radiators that work together to dissipate heat generated by the engine. Coolant, also known as antifreeze, is a mixture of water and ethylene glycol or propylene glycol that flows through the engine and absorbs heat from the engine block, cylinder head, and other components. When the coolant is heated, it circulates through the engine, absorbing heat and carrying it to the radiator, where it is dissipated through a fan and a series of tubes.
The coolant system also includes a thermostat, which regulates the flow of coolant through the engine. When the engine is cold, the thermostat remains closed, preventing coolant from flowing through the engine. As the engine warms up, the thermostat opens, allowing coolant to flow through the engine and maintain the optimal operating temperature.
There are several reasons why coolant may leak from the engine. Some of the most common causes include:
- Worn or damaged hoses
