Purposes of an Engine Coolant in Car :
- The risk of car breakdown reduces with a timely change of coolant
- It prevents overheating of the car.
- Prevents clogging, corrosion, and degradation of the components of the vehicle.
- Removes deposits and rust that builds upon the car over time.
- Reduces the freezing point to -37 degrees Centigrade, so the fluid does not freeze in extremely cold weather
