For today's project, the electric radiator fan motor is going to be replaced on a 1998 ford crown victoria police interceptor because it no longer spins when power is applied.

In a civilian crownvic, the electric fan motor will often last the effective life of the vehicle. But in a police cruiser with lots of idle time, radiator fan motors are left spinning for hours at a time. This extreme duty cycle often causes a rather short lifespan for the electric radiator fan motor.

The first step is to open the hood and pull out the electric fan shroud assembly. This is held in using a couple bolts and a couple plastic tabs which disengage when the fan motor is lifted upwards.

Here's the fan shroud assembly out of the car

Now use a hammer and flat blade screwdriver to slide the retaining disc off the fan motor shaft

And the fan blade assembly can be pulled forward away from the motor

Here is a closeup picture of the three bolts which hold the fan motor to the shroud

And the retaining bolts removed

The fan motor can now be lifted away from the shroud

And the new fan motor installed

The fan blades reinstalled onto the motor output shaft

The fan blade retainer loosely reinstalled using bare fingers

Slid forward using a flat blade screwdriver and hammer

And finally everything can be reinstalled back into the car.
