How can I tell if my GMB fan clutch is broken?
When the engine is off and cool enough to touch, a mechanic should be able to grab the fan and spin it only with reluctance. There should be no wobble laterally (front to back, toward and away from the radiator) in the fan clutch. A bound clutch is also a sign of problems. Any fluid leaking from the fan clutch is a sure sign of a broken clutch.
How does a spring operated fan clutch work?
Spring-operated fan clutches sense temperature from the bi-metal on the front of the fan clutch and electronically-controlled fan clutches are controlled by the vehicle’s Engine Control Unit (ECU), which measures temperature from sensors throughout the engine bay.
What should I do if my fan clutch is going bad?
Silicone fluid leaking from the fan clutch would cause this problem. When the engine is off, there are a few things you can do to check the fan clutch: Spin the fan. Electronic types might freewheel, but most fan clutches should spin with a little effort.
Are there different types of thermal fan clutches?
We manufacture four different types of thermal fan clutches: standard duty, heavy duty, severe duty and truck fan drives. Each type is engineered to simulate the performance, fit and appearance of the original equipment clutch that it replaces. All fan clutches are for specific applications and should only be applied for which they are cataloged.
How does a fan clutch work on a radiator?
A thermal fan clutch reacts to temperature of the air rushing over it from the radiator. As the radiator heats up, the air passing through it also heats up. This heats up a small bi-metallic coil in the face of the fan clutch, releasing an internal valve.
How does a torque limiting fan clutch work?
A torque-limiting fan clutch reacts to engine speed. A centrifugal valve opens to allow the flow of heavy silicone fluid, locking the fan blades to the pulley. At idle and low engine speeds, this fan clutch is fully engaged, gradually disengaging as engine speed increases.
How can I manually engage my Horton fan clutch?
To manually engage your fan clutch, first, disconnect & plug the airline to the fan clutch. Install two Grade-8 (5/16) Whitworth socket head cap screws by aligning the two bolt-holes in the front section of the fan clutch with the two tapped holes located in the pulley sheave.
How much air pressure does a fan clutch need?
This fan clutch requires 90-120 PSI air pressure to DISENGAGE (6.2-8.2 bar). The air pressure is vented to ENGAGE the fan. Any interruption of the air supply will allow the fan to run, keeping it in fail-safe mode. n Maintenance: Clutch Series.
What’s the best way to lock up a fan clutch?
Best way to lock up a fan clutch in a pinch. Got the 73 good and hot today on the highway – mild hills, AC on. How hot? I don’t know, gauge not to the red but definitely in the upper 3/4.
How can you tell when a fan clutch is going bad?
You should be able to audibly detect when the fan clutch engages, with an accompanying rush of air. At idle, as engine temperature increases, a thermal fan clutch will engage at a certain temperature. Torque-limiting fan clutches will disengage at a certain engine speed.
What causes oil to come out of a fan clutch?
Run your finger along the edges of the bearing seal on the backside of the fan clutch. If it comes away with a heavy coating of oil, the culprit is either a crack or a faulty seal. Radial streaks are another potential clue—this happens when oil escapes from the clutch and is then blown outward in all directions by the fan.
