Maintaining Car's Coolant System: Detecting and Fixing Leaks

By Autogos Team

A coolant leak in a car refers to the loss of coolant fluid from the vehicle's cooling system.

Coolant Leak

Coolant is essential for preventing engine overheating and is toxic if ingested.

Importance of Coolant

Coolant can be stored in various parts of the vehicle including the engine, radiator, and hoses.

Coolant Storage

Detecting a coolant leak can be challenging, but checking the coolant reservoir or radiator cap and placing cardboard under the car overnight can help.

Detecting Leaks

Possible sources of coolant leaks include the radiator, hoses, water pump, and engine freeze plugs.

Possible Sources

Leaks can be caused by punctures or wear and tear, or due to old, acidic coolant eroding joints.

Causes of Leaks

If you are losing coolant but do not see any visible leaks, it may be leaking inside the engine or from the heater core.

Invisible Leaks

If you are losing coolant but do not see any visible leaks, it may be leaking inside the engine or from the heater core.

Indicators of Internal Leaks

Regular maintenance, including checking the coolant level and hoses for cracks or leaks, can help prevent coolant leaks from happening.

Preventative Measures

If a coolant leak is suspected, it is important to have the vehicle inspected by a professional mechanic as soon as possible to prevent potential damage to the engine and other components.
