Coolant protects your engine from freezing or overheating, but its effectiveness can diminish over time. It is crucial that you change your coolant and have your cooling system maintained at regular intervals. This will ensure your engine operates at the manufacturer recommended temperature and that your engine remains running trouble free.
How to Diagnose Cooling Problems
If you have green or red liquid pooling under you car or you can see this fluid over other parts in your engine bay, you may have a coolant leak. Leaking coolant can turn into a big problem if it drains enough to reduce the effectiveness of your cooling system. Your vehicle running hotter than normal can also indicate a cooling system issue.
Potential Cooling System Fixes
There are many ways a cooling system can fail, however the most common are as follows:
- Perished coolant hoses
- Radiator failure
- Water pump failure
- Cooling system in need of a flush
- Coolant temperature sensor failure
