- Regulate Engine Temperature: Engines generate significant heat during operation. Coolant circulates through the engine block and radiator, absorbing this heat and preventing the engine from overheating.
- Prevent Freezing: In colder climates, coolant acts as an antifreeze, preventing the engine block and cooling system from freezing and cracking.
- Protect Against Corrosion: Modern coolants contain additives that inhibit corrosion within the engine's cooling system, helping to extend its lifespan.
Key Components of Coolant:
- Base Fluid: Typically a mixture of water and either ethylene glycol or propylene glycol.
- Additives: These include corrosion inhibitors, anti-foam agents, and other chemicals to enhance the coolant's performance.
Importance of Using the Correct Coolant:
- Engine Protection: Using the wrong coolant can lead to corrosion, overheating, and engine damage.
