Suspecting a coolant leak involves several telltale signs. First, check for visible puddles or wet spots under your car, especially after it has been parked for a while. A sweet smell around the vehicle or in the cabin, often described as similar to maple syrup, can indicate leaking coolant. Keep an eye on the temperature gauge on your dashboard; an unexplained rise in engine temperature or frequent overheating is a common symptom. Additionally, low coolant levels in the reservoir despite regular top-ups can signal a leak. Inspect the engine bay for any whitish or greenish deposits around hoses and radiator areas, which may be residue from evaporated coolant. If you notice these signs, it’s crucial to address the issue promptly to avoid engine damage.

Don’t wait—addressing a coolant leak promptly can prevent serious engine damage and costly repairs.
