Symptoms of a Bad or Failing Fan Clutch - YourMechanic.
A dual fan system from Speedway Motors can fit a variety of applications, and flow up to 2.400 cfm. At just under 3 inches thick, they are ideal for tight space applications, or if you want to do away with your mechanical fan altogether. Since you are thinking about electric fans anyway, we can’t forget to discuss the wiring side of things as..
Fan clutch stiff all the time - new clutch, or new silicone?.
You'd have to rotate it backwards to get the air to blow in the opposite direction. Installing the blade backwards just reduces the efficiency of the fan. That is correct. The fan is installed correctly. While setting in the car looking at the fan the fan will rotate counter clockwise. When the engine is running is the air blowing front to back? O. After I fixed it and booted the system ( haven't had any problems even though the PSU was in the wrong direction) I noticed the front fan which is facing in the heatsink ontop of the cpu was spinning normaly getting more air intake on the case as it was never cleaner until I started doing tasks like oppening browsers, oppening game launchers and even windows folders. Without a shroud on the engine side, electric fans have trouble doing anything more than stirring up under hood air. Mounted on the outside, it is recommended to not use a shroud. As a shroud on the outside will do little in assisting how well the fans push air, and will only block a good deal of airflow when the car is moving.

Answer (1 of 6): Basically an Aircraft Jet Engine operates in Five steps! The Diffuser (Front Part with a Fan, in a TurboFan) sucks atmospheric air and reduces the Kinetic Energy. The Compressor, increases the Pressure Energy of the air, getting it ready for Combustion!

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..

Engine rotation is viewed from the flywheel of the engine, clockwise would be Right Hand, and counter-clockwise would be Left Hand. Since you usually cannot see the flywheel with the engine in the boat it can also be determined from the front of the engine. If you are looking at the front of the engine at the belts and pulleys, clockwise would.
New challenge! Radiator fans spin continuously while in.
1 Answer. When you take off the serpentine belt (on a cold engine), turning various accessories and the tensioner by hand should identify any looseness or noise. Could be the water pump, fan, alternator, power steering pump, AC, etc. I would do this sooner rather than later, as one of those going out could be very inconvenient. This article is about the mechanism used in jets. For the turbo like air pressure blower sometimes misnamed Turbo fan, see Centrifugal fan. The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine.
Front hvac or ac blower fan speed problem.
This subject came up in the context of a swap I did to put a 1987 Mustang 5.0L engine with EFI and a serpentine belt drive into a 1979 F100.By the time it came to installing the engine driven cooling fan, I had a ton of parts laying around from various Ford V8's - some standard "clockwise rotation" fans and some reverse "counterclockwise rotation" fans from engines with serpentine belt drives.
Water pump pulley size? Does size matter - Pro-T.
The rational behind throwing a change up with backspin is two fold: 1. A ball that is traveling slowly but spinning fast looks faster than a ball traveling slowly with little or no spin, thereby throwing off the batter's timing more effectively. 2. The ball is spinning backwards slower the longer it travels. When the air/fuel mixture burns it expands in volume, forcing it's way out of the combustion chamber, through the turbine blades, causing it to spin. Because the big fan in front and the compressor behind it are connected to the turbine by a common shaft, they will keep supplying air for combustion, as long as the combustion is turning the turbine.
Fan Clutch Replacement - Popular Mechanics.
Ceiling fan direction summer = counterclockwise (downdraft) Ceiling fan direction winter = clockwise (updraft) To keep cool in summer, your ceiling fan should spin counterclockwise. The counterclockwise direction combined with the blade pitch on fans creates downdraft, which you feel as that welcoming, cool breeze in summer. The jet engine propulsion process begins with fan blades spinning at over 2000 rotations per minute at take-off speed. Typically, an engine is composed of between 16 and 34 fan blades , depending on their aspect ratio, among other factors, drawing in air at a rate of about 2500 pounds per second.
Should a Fan Clutch Spin Freely When Cold or Hot? (Answered).
The wiring harness itself can go bad. Your author has personally had a shredded tire completely pull the fan wiring out of his vehicle. It can happen. The fan wiring is some of the more vulnerable wiring in your Enclave. You can test the voltage going from the fan relay to the fan itself. If it is getting 12+ volts, the fan should be coming on. The radiator fans on cars, being behind the radiator, are sucking - following the natural path of the air that flows as you drive. (Electric fans in this position can then be turned off as the car motion moves enough air already). On indoor fixed installations like diesel gen sets, the fan blows or pushes air from the engine side to the outside. If the fan doesn't come on, you need to look for a broken fuse or breaker. In older cars, you might have a fusible link - this is wire within an insulated block of rubber. If the wire stretches, the wire link could be broken, and you'll need to replace it. A sign of the wire link needing replacing is if your radiator fan fails to turn on.

If they don't come on after about a minute or so then you likely have a problem. The ML has a much larger mechanical cooling fan behind the rad which handles most regular cooling duties. The two front fans come on when extra cooling is needed, either when idling or when A/C is on. HTH. Dobie I ikhan77 Registered 98 ML 320 Joined Feb 4, 2003 6 Posts.
Should a fan clutch spin when hot - Strikingly.
Check the fan clutch front and back see if it looks like a oil leak. The fan clutch it's got a small amount of oil when the oil gets hot because of the engine running the fan clutch gets harder to turn to cool down the engine. If the fan clutch spins freely when the engine is cool down fan clutch might be bad. 8. If your AC offers different fan settings, check if it is set at low speed. If that isn't the case, it could mean the motor bearings need to be oiled or that the capacitor is failing. 4. The fan runs intermittently. When the fan runs intermittently, it could be one of two problems.
Brain fart.. what direction does a s.b.c. rotate? - NastyZ.
The engine cooling system is normally triggered by the temp control sensor/sending unit or ECM/PCM depending on system, but virtually works under the same premise. Once it reaches a 200 plus or minus depending on vehicle the fan will kick on. Many single electric fan systems normally have a high and low. I was thinking that a 6 or 5.5 inch diam water pulley may help to get the water thru the block a little faster. The junkyard had pulleys but were 3 groove but were smaller diam. You want a 1.2 to 1.351 waterpump to crank speed ratio. I use a 6.25" wp pulley and a 7.75" crank pulley to get a 1.24:1 ratio. Your fan has an electromagnetic clutch that should cut the fan in at around 95/100. It is controlled by a fan switch at the front of the engine next to the thermostat. 9 times out of 10 it is this switch that is at fault. The fan will spin freely and be easy to stop when the clutch isn't engaged.
Why does the radiator fan have to start when turning the A/C on?.
There are really two switches in one - one is the pressure safety switch across #1 and #4, the other is the condenser fan switch across #2 and #3. There should be continuity across #2 and #3. However, it may be easier to try this. With the engine off, remove Fan #1 and Fan #2 relays. However, some longitudinal (front to rear) mounted engines use the electric fan as well, but they usually have an engine-powered cooling fan. The electric cooling fan uses a direct current (DC) electric motor with a thermo switch, module or computer control to turn it on or off, depending on coolant temperature or AC operating condition. The fan only keeps running when the engine is off because it is working to get the engine coolant temperature down. This is because the vehicle is equipped with a due Coolant Temperature Sensor, activating the fans when the water and antifreeze reach high temps.
