The coolant fan is solely controlled by the
coolant temp switch on
the engine and the A/C controls. As long as the coolant is above 230
deg or the A/C is on, the fan runs regardless of the car standing
still or at speed.
On some of the 4 cyl A/C cars, there's a two speed fan [RPO VO8];
it has two switches in one shell to activate the fan. These cars are
identified by a large white ceramic resistor on the fan frame rail.

- Disconnect the electrical connector from the bottom of the fan motor.
There is a clip underneath the connector which holds it in.
(Some early models have screw terminals rather than a clip-on connector.)
- There is a clip on the coolant fan assembly which holds the wire in
place. Use a screwdriver to pry it apart.
- Remove the four 10mm bolts (two on top, two on bottom) that hold the
coolant fan in place.
- Remove the fan.
