8 cooling system parts that you should check regularly

8 cooling system parts that you should check regularly

1. Accessory with drive cooling system
Whether your car has a triangular or snake-shaped belt, the belt transfers power from the crankshaft of the engine to the water pump to power the cooling system.Check the belt to make sure it is not loose.Also, look carefully for cracks, wear or rib wear.

2. The water pump pushes coolant into the system
In order for the system to work properly, the coolant needs to be moved throughout the system.The pump uses power from the crankshaft and the serpentine belt to press coolant into the engine and through the rest of the cooling system.Run the engine for a few minutes before checking the pumps.Visually check for leaks around the equipment.Failure to properly heat the passenger compartment may also indicate a water pump failure.

3. The heater core helps regulate the cabin air temperature
The heater core is where the engine cooling system meets the nacelle's AC system.The core is where the engine heat heats the air in the car, which also helps the coolant lose some of its heat before returning to the radiator to cool again.Check the fluid around the heater core or wet spots on the carpet for signs of leakage.Persistent fog in the windshield may also mean the heater core needs to be replaced.

4. Heater and radiator hoses carry coolant through the system
The coolant hose guides the coolant between the rest of the system.Make sure all hoses are securely attached.Check for expansion, breakage and wear.Also, make sure there are no caved in or soft parts.Always check hoses as the engine cools.

5. Cooling fans allow air to flow through the radiators to prevent overheating
Radiator fans increase airflow to help the system cool down more efficiently.Ensure that all blades on the cooling fan are in good condition and not damaged.Fan blade noise is a good indicator of damage.

6. Before returning to the radiator, measure the coolant temperature with the thermostat
The thermostat measures the temperature of the coolant before it returns to the radiator.In this way, your car engine computer can track the condition of the car's cooling engine and ensure that the cooling system is working properly.

7. The radiator exchanges coolant heat with the outside air
As the coolant flows through the radiator, cool air blows through the radiator, cooling the coolant and then circulating it through the engine.Check that the coolant concentration in the coolant is adequate.Refer to the user's manual for the location of the reservoir.Most manufacturers recommend using 50% antifreeze and 50% water mixture.Make sure the fluid reaches the "full" line.If not, pour in enough antifreeze to reach the production line.AutoZone store assistant can help you find the right antifreeze for your vehicle.

8. Radiator covers are easy to fill
The radiator usually acts as a reservoir for coolant. The lid seals the system and provides a convenient way to add more coolant when needed.Make sure the radiator cap is always tight and firm so that it is properly sealed.Do not remove the engine while it is hot.Here are some guidelines on when to replace the radiator cap:
  • Radiator caps may deteriorate after 40,000 to 50,000 miles
  • Usually, when replacing the thermostat, pump, or radiator, the radiator cap should be replaced.This will ensure that the system is operating under the right pressure
