Recognizing these symptoms promptly can prevent costly repairs and maintain your vehicle’s performance.

How to Identify a Coolant System Leak?

Detecting a coolant system leak involves observing both your vehicle’s behavior and physical signs. Here’s a comprehensive guide to help you identify a potential leak:

• Low Coolant Levels: Regularly check your coolant reservoir. If levels are consistently low, it may indicate a leak.
• Visible Puddles: Look for green, orange, or pink puddles under your car, especially after parking.
• Overheating Engine: An overheating engine, indicated by a rising temperature gauge, can be a symptom of a coolant leak.
• Sweet Smell: A sweet, syrupy odor inside or outside your car can suggest a coolant leak.
