Radiator and Condenser Fan Controls
Description
Fan control system:
The cooling fan system is comprised of the radiator fan, condenser fan (left and right), engine compartment fan, radiator
fan low relay, radiator fan high relay, condenser fan relay, engine compartment fan relay, radiator fan resistor, radiator
fan control sensor, A/C pressure switch, fan control unit, climate control unit, and ECM.
The fan control unit controls the operation of the radiator fan and condenser fans.
It uses inputs from the radiator fan control sensor and the A/C pressure switches (A and B) in the A/C system to deter-
mine when the fans should run and at what speed.
Additionally, the temperature switch shuts down the A/C system if the engine coolant temperature (ECT) exceeds
266°F (130°C). If the pressure in the A/C system is higher than normal, pressure switch A closes and the fans will run at
high speed only. See the A/C section for the description and specifications of that function.ProCarManuals.com

Cylinder Heads
Removal
Engine removal is not required in this procedure.
CAUTION: To avoid damaging the cylinder heads, wait until the engine coolant temperature drops below 100°F (38°C) before loosening the retaining bolts.
NOTE:
Inspect the timing belt before removing the cylinder
heads.
Turn the crankshaft so that the No. 1 piston is at top
dead center (TDC (page 6-25, 26). Mark all emission hoses before disconnecting them.
1. Disconnect the negative terminal from the battery.
2. Remove the expansion tank cap.
Use care when removing the expan-
sion tank cap to avoid scalding by engine coolant or
steam.
3. Raise the car.
4. Remove the right rear wheel/tire.
5. Remove the engine under guard, then remove the front exhaust pipe.
6. Remove the rear exhaust pipe.
CAUTION: Do not use an air wrench or hammer to
remove or install the exhaust system unless you
first remove the heated oxygen sensors.
