Do you need a solenoid valve for a fan clutch?
Freon Pressure Switch, and N.C. Solenoid Valve are the only controls absolutely necessary for Fan Clutch operation. The N.C. Manual Switch, Air Pressure Switch, and Indicator Light are all optional controls and may be left out of the circuit.
What are the symptoms of a bad or failing downshift solenoid?
An illuminated Check Engine Light is another symptom of a bad or failing downshift solenoid. If the computer detects a problem with the downshift solenoid circuit or function it will set off the Check Engine Light to alert the driver of the issue.
How to test a check engine light test?
Automotive Circuit Testing 101 – Check Engine Light Help 1 Open circuit (or partially open such as a chaffed line which causes high resistance due to heat when circuit load is on) 2 Short to power 3 Short to ground 4 High resistance (usually caused by corrosion or poor connections)
What causes an open circuit on a check engine light?
If you find a problem then check the wiring harness to locate the open wire and retest. Check engine light issues caused by open circuits are often caused by chaffed wiring harnesses or loose wire pins at the connectors causing intermittent or poor connection. So be sure to check for these.
What causes a hydraulic fan pump to go out?

What’s the best way to repair a hydraulic fan?
Remove Both Hoses. Spin the Fan Manually by hand and watch the old Fluid drain out. Add fluid as necessarily to the Opposite hose, continue this until you see New fluid. Unbolt the Hydraulic Fan Reservoir and Remove both Hoses attached. Set the Reservoir aside. Step 2 *Under the car you go!*
How to repair a hydraulic fan pump actuator?
Proceed by installing your new actuator in by first re-connecting your wiring harness connection and set your new Actuator in the old ones place. Then with your T-40 Socket Start tighting it in. Remember Tight is Tight and Too Tight is broken. You dont have to be super man here and tighten it so no man will ever be able to get it off.
Normally Closed (N.C.) NOTE An electrical system wired N.C. will require a normally open (N.O.) Solenoid Valve. Also note the N.C. Thermal Switch, N.C. Freon Pressure Switch, and N.O. Solenoid Valve are the only controls absolutely necessary for Fan Clutch operation.
Why is the solenoid on my fan not working?
The solenoid is normally powered up to pass air to the clutch to keep it from engaging. This problem is occurring when the solenoid is powered down. It is a block and bleed function where it blocks the supply pressure and then bleeds the output going to the clutch to cause it to engage.
How do you release the clutch on a Horton fan?
Allow 10-15 seconds for each application of the disc. To manually activate the clutch, you simply need to plumb a compressed air line directly to the fan hub. Then use a toggle switch to apply and release the air. This allows the internal spring to compress and release the clutch, with air vented to reapply it.
When does a fan cluthc turn on or off?
With a fan cluthc your fan will rotate constantly regardless. The clutch engages and locks the blade to it so that it spins faster than normal the hotter that it gets. The only time that your fan will not spin is when the motor is off. It is a common misconception that the fan will only spin when…

What does it mean when the solenoid fails on a truck?
Meaning, the solenoid is grounded, allowing air flow to the clutch to keep the fan off. If the fan solenoid fails or there is low air pressure, the fan will stay on.
What should the pressure be on a solenoid fan?
It should release it immediately when the solenoid is powered down. Pretty much must be a defective unit since it says it is rated for 140 psi. No way the wet air is that high of a pressure. Air keeps the fan off no air th fan should come on. Reverse from the m939 trucks.
