Your car is full of other fluids that need to be well maintained to help it run properly, one of which is your coolant.
Engine coolant has three important functions
- First is to product the radiator, water pump and other parts from corrosion.
- Second is to keep the engine from over heating, or keep it cool.
- Third is to keep the engine from freezing.
If your vehicle is running on substandard coolant, the engine can overheat extremely fast, leading to mechanical breakdown and failure. In the picture below you can see the obvious difference between good and bad coolant fluid.
