How do I know if my coolant needs replacing?
Your vehicle's coolant, also known as antifreeze, plays a crucial role in keeping your engine running at the optimal temperature. Over time, however, the coolant can become contaminated or lose its effectiveness, requiring replacement. Here's how to tell if your coolant needs to be changed.
Signs Your Coolant Needs Replacing
- Discoloration or cloudiness: Fresh coolant is typically bright green, yellow, or orange. If it appears discolored, murky, or has a milky appearance, it's time to replace it.
- Foul odor: Healthy coolant should have a sweet, almost fruity smell. If it has a pungent, unpleasant odor, it's likely time for a change.
- Leaks or low coolant levels: If you notice coolant leaks or your coolant level is consistently low, it could be a sign that the coolant is no longer effectively circulating through the system.
- Overheating issues: If your engine is running hotter than normal, it may be an indication that the coolant is not properly regulating the temperature.
These are all clear signs that your coolant needs to be replaced. It's important to address any coolant-related issues promptly to prevent further damage to your engine.
