There are signs that your vehicle’s cooling
system is not functioning properly. The most noticeable symptoms are
overheating, leaks, a smell of antifreeze, needing to continuously add coolant, and poor or no heat in the vehicle.
The engine cooling system affects a vehicle’s
overall dependability and engine longevity. The key parts of the cooling system
remove heat from the engine and automatic transmission and dissipate heat 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.
Coolant should be changed annually on most
vehicles. However you should always consult your vehicle 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.
Sullivan Tire recommends checking the coolant
level with every oil change. In fact, as part of our oil change service our
Certified Technicians check and top off all vehicle fluids. We also perform a
visual inspection of hoses, belts and the radiator to help identify cooling
system problems before they happen.
In addition, the cooling system is also an integral part of how the heating system in your car functions. The heat from the antifreeze is taken into your vehicle through a series of vents and duct work. So keeping your radiator and cooling system in good working order is particularly important in the winter months.
