What is it?
The engine cooling system affects your car’s overall dependability and engine longevity. Cooling systems
have advanced over the years with new coolant formulations and new radiator designs and materials. If you
suspect a problem with your cooling system, you should check it immediately.
What does it do?
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.
Typical Wear and Tear
Factors that affect the replacement of cooling system parts include:
• Driving habits
• Operating conditions
• Type of vehicle
• Type of coolant
• Frequency of regular maintenance such as coolant changes
Symptoms
• Overheating
• Sweet smell
• Leaks
• Repeatedly need to add fluid
