When a fan is failing
An electric fan problem usually shows up as overheating in traffic or at idle while the temperature stays normal at highway speed. Weak A/C at a stop is another sign, since the condenser also relies on fan airflow. You may hear a grinding or buzzing motor, or notice the fan never turns on.
A blown fuse, a failed relay, a bad coolant temperature sensor or a damaged connector can also stop the fan, so test those before you replace it.
Choosing the right assembly
Fan assemblies here include single and dual fan units, some covering both the radiator and condenser. Motors are brushed or brushless. Brushless motors are common on newer vehicles and use a built-in control module.
Check the connector type and terminal count, the shroud shape and whether you need a dual assembly. Mounting hardware is not included on most units, so reuse your original bolts or clips. The fitment table shows engine and A/C differences.
Safe installation
Electric fans can start without warning on some vehicles, even with the key off, if the engine is hot. Disconnect the negative battery cable before working near the fan.
Most assemblies lift out after you remove the upper mounting bolts and unplug the connector, though some need the upper radiator support or air box moved. Once installed, run the engine to operating temperature and confirm the fan turns on, and also with the A/C on.
Radiator Fan questions
Why does my car overheat only when idling?
At highway speed, air moves through the radiator on its own. At idle, the electric fan has to do that work. Overheating only at a stop often points to a fan that is not running or running too slowly.
How do I test a radiator fan?
With the engine warm or the A/C on, the fan should run. If it does not, check the fuse and relay, then test for power at the fan connector. Power present with no fan movement usually means a failed motor.
Is a radiator fan the same as a condenser fan?
Some vehicles use one fan for both, some use a separate fan for the condenser, and some use a dual assembly. The package contents on each listing show whether it is a radiator fan or a radiator and condenser fan assembly.
