How does a hydraulic fan drive system work?
A hydraulic fan drive system allows variable fan speed independent of the engine speed. It provides only the cooling that is required throughout the operating range of the vehicle including such requirements as the maximum engine rated torque point where high cooling may be required at lower than maximum engine speed.
How does the GC cooling smart fan module work?
GC Cooling’s Smart Fan Module is easy to install with no programming required. All you do is replace the fan’s motor cover with the Smart Fan Module. The Module has additional inputs and outputs for a mechanical override switch, air conditioning input, output to control additional fans.
How does ramping Parker hydraulic fan drive work?
The full cooling control of hydraulic fan drives enables ramping Parker hydraulic fan drive systems are efficient throughout the engine and vehicle’s operating range. Traditional on/off clutch solutions operate only at maximum speed and can suddenly drain power to the vehicle and slow down the work cycle.
How is the speed of the fan motor adjusted?
In the fan drive circuit, fan speed is adjusted by providing a varying Pulse Width Modulated electrical current signal to the proportional relief valve which controls the flow to the fan motor. Excess flow is bypassed to the reservoir. Performance and Value:
How does a hydraulic cooling fan work in a hydraulic system?
Open type system cooling solution by fan: By specific function proportional manifold to controls the rotation speed and direction of fan motor in open type system. 1. Solenoid valve controls hydraulic motor steering. 2. Bi-directional pressure relief valve controls the pressure of hydraulic motor running.

Hydraulic fan drive systems enable full fan control yielding significant power and fuel savings. Parker hydraulic fan drive systems are efficient throughout the engine and vehicle’s operating range. Traditional on/off clutch solutions operate only at maximum speed and can suddenly drain power to the vehicle and even require downshifting.
Why is my engine cooling fan running at constant high speed?
There is no Schraeder valve on the sensor and removing the sensor allows the gas to escape into the atmosphere. Replace the sensor and confirm good location of the wiring connector. Locate wiring in order to avoid chafing of harnesses. Use the AssistPlus to check the reading in the climate control module.
What are the symptoms of a bad cooling fan?
Common signs include the engine overheating, cooling fan only working at certain speeds, and the fan never turning off.
What causes a car fan to run all the time?
If the relay shorts internally, it may cause power to be permanently switched on, which will cause the fans to run at all times. Depending on the wiring setup of the vehicle, this may cause them to stay on even when the vehicle is off, which will drain the battery.
What are the symptoms of a bad cooling fan motor?
Cooling fans do not come on The most common symptom of a faulty cooling fan motor are cooling fans that do not come on. If the cooling fan motors burn out or fail, the cooling fans will be disabled. The cooling fan motors work together with the cooling fan blades to pull air through the radiator.
What does it mean when Fan is running at constant high speed?
If it is higher, the air-conditioning control module presumes that the pressure is high and assigns the fan control module to run at 90% PWM actuation. Also check the AAC pressure at stand still / cold. This should be approximately 5 – 6 bar. Confirm that there are no wiring issues to the sensor. Pin 2 – Signal. Reference values:
What kind of motor does a cooling fan use?
It is the job of the cooling fans to provide that air flow, and they do so using electric motors. The electric motors found on many cooling fans are not much different than regular industrial use electric motors, and are often a serviceable or replaceable component of the cooling fan assembly.
