Could a leaking water pump be causing the antifreeze smell in my car?

A failing water pump in your car can lead to the presence of an antifreeze smell. This is a common symptom associated with a water pump that is not functioning properly.

One of the most noticeable signs of a failing water pump is the leakage of coolant. Over time, the gaskets and seals of the water pump can wear out or develop cracks, which can cause coolant to seep through and drip from the pump. Look for any indications of dampness or puddles around your vehicle to identify a possible leak.

If you suspect a leak in your water pump, it is advisable to promptly replace the pump and ensure that any loose engine bolts are tightened. This will help to prevent any further damage or issues with your car's cooling system.
