What is it?
Coolant helps to keep the engine cool and operating at the correct temperature.
What does it do?
Coolant is circulated through the engine to absorb heat from the engine components. The cooled engine coolant is then returned to the radiator where it releases the heat into the air. In addition to keeping the engine cool, the coolant also helps to protect it from corrosion and freezing.
Typical Wear and Tear
Over time, an engine’s coolant will naturally break down and become less effective. This is due to a number of factors, including the exposure to high temperatures, chemicals, and other pollutants. As the coolant breaks down, it will lose its ability to protect the engine from corrosion and overheating. In addition, the coolant will become contaminated with engine oil and other fluids, which can clog the radiator and reduce its efficiency.
- Coolant is discolored or contains particles
- Increased engine operating temperature
- Steam from under the hood
