The document outlines common problems associated with a failed radiator fan, which can lead to car overheating. Key issues include a failed temperature sensor, fan clutch, cracked fan wires, a blown fuse, and low coolant levels. It emphasizes the importance of diagnosing these problems early and consulting a mechanic for repairs.

1. What are the Common
Problems Found in a
Failed Radiator?

2. Radiator fan can cool the
radiator to stop the car from
overheating.

3. Small problems with the
radiator fan may cause serious
damages to the car.

4. Failed fans are difficult to
find because you can’t hear
them when you sit inside
the car.

5. When the radiator fan fails,
you will notice a number of
problems in the car.

6. Below points define the
common problems found in a
failed radiator.

7. Failed temperature
sensor

8. Radiator fan reads the
temperature of the cooling
system through the
temperature sensor.

9. If the sensor isn’t working,
then the fan won’t come on
and lead to overheating.

10. Failed fan clutch

11. Fan clutch is the assembly
that holds the radiator fan
to the engine and makes it
turn.

12. If the clutch is failed, the
springs with the clutch can
wear out or corrode over the
years.

13. Cracked fan wires

14. Check the fan wires of the
car when the engine is
heating, but unable to kick
the fan.

15. If the wires are cracked,
check both the wires and
fan relay for replacement.

16. Blown fuse

17. Make sure the fuse for the
radiator fan is intact to
control the cooling system.

18. If it is not, then replace the
fuse immediately and take
care of the problem.

19. Coolant level

20. Check the coolant level in
the engine by looking at the
reservoir.

21. Make sure that the coolant level
is up to its maximum level for
avoiding the overheating.

22. When you notice any of the
problems in the car, check
the radiator immediately.

23. Take the car to a reputed
mechanic for diagnosing the
radiator and fix the issues.
