Symptoms of a sick cooling system

Cooling System

With the hot summer temperatures on the rise, knowing the symptoms of a sick cooling system are critical to your car’s survival, since cooling system failure is a leading cause of vehicle breakdowns. The most noticeable symptoms include overheating, leaks, a sweet smell of antifreeze and repeatedly needing to add coolant, according to Concord Tire.


The primary job of the engine’s cooling system is to remove the heat that is generated during the combustion process. The coolant temperature can be well over 200 degrees and that heat has to go somewhere, otherwise, engine components are going to start failing. The key parts of the cooling system remove the heat from the engine and automatic transmission and dispel it to the air outside. The water pump circulates coolant through the engine. The coolant absorbs heat and returns it to the radiator where heat is dissipated. The thermostat regulates the coolant temperature to keep it consistent for efficient engine operation.

A major factor that affects the replacement of cooling system parts is the frequency of regular maintenance, such as coolant changes. Motorists should consult their owner’s manual for specific recommendations about how often to change antifreeze and flush the coolant system. A coolant flush and fill is basic to cooling system maintenance as new antifreeze helps the engine run cooler and a flush removes dirt or sediment that could damage other cooling system parts.
