The cooling fan in a Mazda 626 is essential for maintaining the optimal temperature of the engine. It draws air through the radiator when the vehicle is stationary or moving slowly, helping to dissipate heat and prevent the engine from overheating. A functioning radiator fan ensures the longevity and efficiency of the engine by regulating its operating temperature.
Engine Overheating: One of the most noticeable signs is the engine temperature rising above normal levels, especially when idling or in stop-and-go traffic.
Reduced Air Conditioning Performance: A malfunctioning cooling fan can lead to insufficient cooling in the cabin because the fan also helps cool the air conditioning condenser.
Unusual Noises: Grinding or whining noises coming from the radiator area may indicate a problem with the fan blades or motor.
Coolant Loss: Overheating can cause coolant to boil over or leak, leading to lower coolant levels.
Warning Lights: The temperature gauge on the dashboard may read higher than normal, or a warning light may illuminate.

Regular Inspection: Periodically check the fan blades for cracks, chips, or debris that might impede operation. Ensure the fan shroud is intact to maximize airflow efficiency.
Electrical Connections: Inspect the wiring and connectors for signs of corrosion or damage. A faulty connection can prevent the fan motor from receiving power.
Fan Motor Testing: If the fan isn't operating, test the motor by directly supplying power to determine if the issue is with the motor or the control circuit.
Professional Assistance: If unsure about diagnosing or replacing the cooling fan, consult a professional mechanic to avoid potential damage to the vehicle.
Use Quality Parts: When replacing the fan, use high-quality components to ensure reliability and longevity.

Q: What causes the cooling fan in a Mazda 626 to stop working?
A: Common causes include a blown fuse, a faulty relay, damaged wiring, a malfunctioning fan motor, or issues with the coolant temperature sensor.
Q: Can a bad cooling fan affect my car's performance?
A: Yes, without proper cooling, the engine can overheat, leading to reduced performance, increased emissions, and potential engine damage.
Q: How can I test if my cooling fan is working?
A: You can start the engine and let it idle until it reaches operating temperature; the fan should turn on automatically. Alternatively, you can use a diagnostic tool or consult a mechanic for testing.
Q: Is it safe to drive with a faulty cooling fan?
A: Driving without a functioning cooling fan can cause the engine to overheat, especially in traffic or warm weather, which can lead to severe engine damage. It is not recommended.
Q: Does the cooling fan run all the time?
A: No, the cooling fan operates when the engine temperature reaches a certain point or when the air conditioning is in use, depending on the vehicle's design.

Replacing a faulty cooling fan promptly is crucial to prevent engine overheating. Overheating can cause warped cylinder heads, blown head gaskets, and other severe engine issues that are costly to repair. A new cooling fan restores proper airflow through the radiator, maintaining the engine's optimal temperature and ensuring reliable vehicle performance.
Regular Coolant Changes: Maintain the recommended coolant levels and replace the coolant as per the manufacturer's schedule to prevent corrosion and buildup.
Check for Leaks: Inspect hoses and connections for any signs of coolant leaks, which can lead to overheating.
Monitor Dashboard Gauges: Keep an eye on temperature gauges and warning lights to catch cooling issues early.
Service Air Conditioning System: The cooling fan also assists in the operation of the air conditioning condenser; regular A/C maintenance can benefit the cooling system.
