Replace faulty component.
Fan won't cycle on when airconditioning test is performed.
Outside air temperature is too low, there is alow refrigerant charge or refrigerant pressureswitch is faulty.
Check air conditioning system.1. Replace pressure switch ifrequired.
2.
Overtemp warning activatesbefore fan engages.
Defective overtemp warning switch. Replace overtemp warning switch.
Engine appears to overheat.(Fan won't engage whenengine coolant temp gauge isabove 195−205°F orovertemp warning activatesbefore fan engages.)
Air Solenoid valve may be plumbedincorrectly
1.
Overtemp warning switch faulty(warning light activates prematurely).
2.
Overtemp warning switch is too faraway from the fan temp switch.
3.
Temp gauge is faulty (reads high).4. Fan temp switch is faulty.5.
Check solenoid plumbing.Replumb solenoid valve.
1.
Replace overtemp warningswitch.
2.
Move overtemp warning switchas close to the fan temp switchas possible.
3.
Replace temp gauge.4.
Replace fan temp switch.5.
Fan engages at low enginetemperatures while vehicle ismoving.
Normal condition in extremely hotweather or at slow vehicle speeds inwarm weather.
1.
Faulty temp gauge.2.
A/C system overcharged or condensercovered with debris.
3.
Refrigerant pressure switch may befaulty.
4.
Fan temp switch is faulty, if fanengages at low engine temp and A/Cis OFF.
5.
Normal condition in hotweather.
1.
Replace temp gauge orsender.
2.
Check A/C system.3.
Replace pressure switch ifnecessary.
4.
Replace fan temp switch.5.
Fan won't run under anycondition. Air line may be leaking (Horton/Evans
air−on fan drives).1.
Wiring may be shorted and/or fuses,circuit breakers blown.
2.
Air solenoid may be faulty. Test airsolenoid valve by shorting across theterminals of the temp switch toenergize the air solenoid valve and toactivate the fan drive.
3.
Check air lines. Fix wherenecessary.
1.
Check wiring, fuses, and circuitbreakers.
2.
If solenoid does not activate,replace solenoid.

Normally Closed Fan Clutches
Problem Possible Cause Solution
Fan runs all the time whenthe air conditioning is OFF. Manual override switch is ON.1.
Air solenoid valve may be faulty orplumbed incorrectly.
2.
Air line to clutch may be leaking(Bendix/Kysor air−off fan drives).
3.
Fan temp switch may be stuck open;with engine temp below 180°F shortacross terminals, if fan turns off,switch is faulty.
4.
Pressure switch may be stuck open;turn off A/C system, if fan continues torun, short across pressure switch, iffan stops, pressure switch isdefective.
5.
Turn manual override off.1. Check air solenoid valveplumbing, replace valve iffaulty.
2.
Check air lines, fix wherenecessary.
3.
Replace fan temp switch.4.
Replace pressure switch.5.
Fan runs all the time whenthe air conditioning is ON. This is a normal condition in
extremely hot weather; spray wateron A/C condenser (fan shoulddisengage for a short period of timeand then re−engage after waterevaporates).
1.
Air conditioning system may beover−charged or condenser coveredwith debris. Turn OFF the A/Csystem; if the fan stops, therefrigerant pressure switch isfunctioning.
2.
Pressure switch may have drifted outof calibration; use pressure gauge tocompare actual fan−on and fan−offpressures vs. specified pressures.
3.
Normal condition in hotweather.
1.
Service A/C system. CheckA/C pressure and condenser.
2.
If out of calibration, replacepressure switch.
3.
Fan operation is erratic.Loose electrical connection.1.
Fan temp or pressure switch may befaulty.
2.
Check wiring; fix wherenecessary.
1.
If other system componentsand connections check outokay, (a) replace pressureswitch if erratic fan operationis associated with airconditioning at idle or (b)replace fan temp switch if theerratic operation occursprimarily when the engine ishot.
2.
Fan cycles frequently whenengine is hot.
The fan should remain engaged long enoughto reduce temperature 7−10єF. The fan tempswitch is defective if the fan disengages afteronly a 3−4є reduction.
Replace fan temp switch.
Troubleshooting 13−FAN CLUTCHES

Normally Closed Fan Clutches
Problem Possible Cause Solution
Fan cycles frequently whenvehicle is stationary with A/CON.
Up to 4 cycles per minute is a normal conditionfor conventional control systems; turn off airconditioning system and cycling should stop.
To reduce cycling by up to 90%, installan Index K7 fan control system.
Fan turns on wheneverignition is on (turns off whenengine gets hot).
Air solenoid valve plumbed backwards. Check solenoid installation instructions;plumb correctly.
Control system fuses blown.If fuse blows whenever the ignition isturned on, the problem is most likelyrelated to a fault in the wiring.
1.
If the fuses blow only when the fanengages, the fault is probablyassociated with the solenoid valve.
2.
Check wiring, fix wherenecessary.
1.
Use an ohmmeter to check fora shorted solenoid coil (thecoil resistance should begreater than 14 ohms). Ifshorted, replace air solenoidvalve.

Fan won't cycle on when airconditioning test is performed.
Outside air temperature is too low, there is alow refrigerant charge or refrigerant pressureswitch is faulty.
Check air conditioning system.1. Replace pressure switch ifrequired.
2.
Override warning activatesbefore fan engages.
Defective overtemp warning switch. Replace overtemp warning switch.
Engine appears to overheat.(Fan won't engage whenengine coolant temp gauge isabove 195−205°F orovertemp warning activatesbefore fan engages.)
Air Solenoid valve may be plumbedincorrectly
1.
Overtemp warning switch faulty(warning light activates prematurely).
2.
Overtemp warning switch is too faraway from the fan temp switch.
3.
Temp gauge is faulty (reads high).4. Fan temp switch is faulty.5.
Check solenoid plumbing.Replumb solenoid valve.
1.
Replace overtemp warningswitch.
2.
Move overtemp warning switchas close to the fan temp switchas possible.
3.
Replace temp gauge.4.
Replace fan temp switch.5.
Fan engages at low enginetemperatures while vehicle ismoving, with air conditioningON.
Normal condition in extremely hotweather or at slow vehicle speeds inwarm weather.
1.
Faulty temp gauge.2.
A/C system overcharged or condensercovered with debris.
3.
Refrigerant pressure switch may befaulty.
4.
Fan temp switch is faulty if fanengages at low engine temp and A/Cis OFF.
5.
Normal condition in hotweather.
1.
Replace temp gauge orsender.
2.
Check A/C system.3.
Replace pressure switch ifnecessary.
4.
Replace fan temp switch.5.
Fan won't run under anycondition. Air line may be leaking (Horton/Evans
air−on fan drives).1.
Wiring may be shorted and/or fuses,circuit breakers blown.
2.
Air solenoid may be faulty. Test airsolenoid valve by shorting across theterminals of the temp switch toenergize the air solenoid valve and toactivate the fan drive.
3.
Check air lines. Fix wherenecessary.
1.
Check wiring, fuses, and circuitbreakers.
2.
If solenoid does not activate,replace solenoid.

Troubleshooting 13−FAN CLUTCHES
13 − 73
Normally Open Fan Clutches
Problem Possible Cause Solution
Fan runs all the time whenthe air conditioning is OFF. Manual override switch is ON.1.
Air solenoid valve may be faulty orplumbed incorrectly.
2.
Air line to clutch may be leaking(Bendix/Kysor air−off fan drives).
3.
Fan temp switch may be stuck closed;with engine temp below 180°Fdisconnect wiring, if fan turns off,switch is faulty.
4.
Pressure switch may be stuck closed;turn off A/C system, if fan continues torun, disconnect wiring to pressureswitch, if fan stops, pressure switch isdefective.
5.
Turn manual override off.1. Check air solenoid valveplumbing, replace valve iffaulty.
2.
Check air lines, fix wherenecessary.
3.
Replace fan temp switch.4.
Replace pressure switch.5.
Fan runs all the time whenthe air conditioning is ON. This is a normal condition in
extremely hot weather; spray wateron A/C condenser (fan shoulddisengage for a short period of timeand then re−engage after waterevaporates).
1.
Air conditioning system may beover−charged or condenser coveredwith debris. Turn OFF the A/Csystem; if the fan stops, therefrigerant pressure switch isfunctioning.
2.
Pressure switch may have drifted outof calibration; use pressure gauge tocompare actual fan−on and fan−offpressures vs. specified pressures.
3.
Normal condition in hotweather.
1.
Service A/C system. CheckA/C pressure and condenser.
2.
If out of calibration, replacepressure switch.
3.
Fan operation is erratic.Loose electrical connection.1.
Fan temp or pressure switch may befaulty.
2.
Check wiring; fix wherenecessary.
1.
If other system componentsand connections check outokay, (a) replace pressureswitch if erratic fan operationis associated with airconditioning at idle or (b)replace fan temp switch if theerratic operation occursprimarily when the engine ishot.
2.
Fan cycles frequently whenengine is hot.
The fan should remain engaged long enoughto reduce temperature 7−10єF. The fan tempswitch is defective if the fan disengages afteronly a 3−4єF reduction.
Replace fan temp switch.

Normally Open Fan Clutches
Problem Possible Cause Solution
Fan cycles frequently whenvehicle is stationary with A/CON.
Up to 4 cycles per minute is a normal conditionfor conventional control systems; turn off airconditioning system and cycling should stop.
To reduce cycling by up to 90%, installan Index K7 fan control system.
Fan turns on wheneverignition is on (turns off whenengine gets hot).
Air solenoid valve plumbed backwards. Check solenoid installation instructions;plumb correctly.
Control system fuses blown.If fuse blows whenever the ignition isturned on, the problem is most likelyrelated to a fault in the wiring.
1.
If the fuses blow only when the fanengages, the fault is probablyassociated with the solenoid valve.
2.
Check wiring, fix wherenecessary.
1.
Use an ohmmeter to check fora shorted solenoid coil (thecoil resistance should begreater than 14 ohms). Ifshorted, replace air solenoidvalve.
