What is Coolant and How Does it Work?
Coolant, also known as antifreeze, is a mixture of water and ethylene glycol or propylene glycol. Its primary function is to absorb and dissipate heat from the engine. When the engine is running, the coolant circulates through the engine block, radiator, and hoses, absorbing heat and transferring it to the radiator, where it is dissipated.
Here’s a step-by-step explanation of how coolant works:
- The engine block absorbs heat from the combustion process.
- The heat is transferred to the coolant, which circulates through the engine block and radiator.
- The coolant absorbs the heat and carries it to the radiator.
- The radiator dissipates the heat to the air, cooling the coolant.
- The cooled coolant returns to the engine block, repeating the cycle.
