	Jaguar XJ-S Electric Radiator Fan Installation
		Electric fans have several advantages over belt-driven fans, including a reduced load on the engine and reduced noise, but improved cooling is not likely to be a result.
		Electric fans also have the benefit that they can operate after shutdown to counteract heat soak, but the small stock electric fan on the XJ-S is adequate for this purpose.
		Note that the GM electric fan is not very compact or "flat"; in fact, it protrudes rearward about 4" from the surface of the shroud, as well as about 1" forward (right up close to the back side of the radiator).

		Fans became made of all materials such as parchment, silk, lace, ostrich feather and often mounted fans on carved handles of ivory, tortoise-shell, horn, bone or sandalwood.
		In centrifugal fans, air is led through pipe to the center, or eye, of the impeller, which forces it radially out into the spiral casing from which it flows to a discharge pipe.
		Fans are used for circulating air in rooms and buildings; for cooling motors and transmissions; for cooling and drying people, materials, or products; for exhausting dust and fumes; for forced draft in steam boilers; and in heating, ventilating, and air-conditioning systems.

	FORDMUSCLE.com web-magazine - Electric Fan Installation for 5.0 Mustangs
		Perhaps the greatest level of apprehension regarding electric fans, is the fear of their ability to sufficiently cool the engine.
		While it is true that selecting the wrong electric fan can cause the engine to run hotter, selecting the correct fan for your application will actually cool the engine just as well as a stock fan, and in many cases will alleviate problems with a engine that runs too hot.
		The fan also needed to have an AC activated switch (air conditioning places additional cooling demands, thus you want a fan that switches on automatically when then the AC is turned on.) Finally the fan had to be a direct, no-hassle, bolt in.

	The Myth Of The Electric Fan
		The fan to cool a 400HP engine is the same size fan as would be used to cool a 200HP engine since both engines are producing the same amount of heat during idle and light cruising.
		Recall that the fan is not even used when at speed, as the natural flow of the of air through the radiator is more then enough (much more then a fan, in fact) to keep the car cool.
		Without the stock fan shroud in the way, there is much more room in the engine bay, as well as room to route things like intercooler piping, cold air intakes, etc. An electric fan may also be required when going to certain aftermarket radiators that do not have provision for mounting the stock fan shroud.

	Jeep 4.0 Dual Electric Fan Conversion
		The main fan is a 15" diameter viscous clutch fan that is mounted to an engine-driven pulley.
		I bolted the electric fan onto it using the mounting tabs that came with the fan.
		The fan was wired up so that it was triggered by a second relay (I had a spare relay handy) when the A/C is switched on or when the engine temperature reaches 220F. You can add a switch to operate the fans* manually if you wish, but I didn't apply that option.

	Electric Fan Systems FAQ
		An electric fan is needed for those times when there isn't enough airflow (cfm) through the radiator to maintain the proper coolant temperature.
		A pusher fan is a fan that is installed ahead, or in front of the radiator, and wired so that when it is running, the air is "pushed" through the radiator core.
		It is possible to gain clearance by moving the electric fan up, down or to the side of the radiator, thereby avoiding contact with the water pump or exhaust system.

		Fan is mounted as close to the rad as possible.
		The fan's upper brackets were bent to bring the mounting bolt hole forward on the car and to lower the fan about 1" so it is not eclipsed by the bulkhead.
		The fan's negative power wire is grounded to the chassis, near the fan on the front bulkhead.

	Vintage Fan Restoration Process - Vintage Fans, L.L.C.
		Whatever the fan needs to make it run and operate as it did when it was new is the rule that we use in determining what each fan will need to complete the restoration.
		The body of the fan either goes through a process of cleaning, or the old finish is removed completely and the parts are bead blasted in order to prepare them to receive the new finish.
		The electric motor and speed coil is cleaned, inspected, and a series of tests applied to check them for grounds, open circuits, etc. Once it is determined what the motor and speed coil need, they will be repaired and reinsulated to insure that they are electrically sound.

	Electric Fan
		Even after getting out and turning the knob so the fan stayed on all the time and running with the AC off, the remainder of the trip was spent right near the max point on the temp gauge and I shut down several times to cool a bit.
		First thing you'll notice about the fan is that it mounts on two square tubes that run from one side of the shroud to the other.
		I'd been fighting overheating problems since switching to the electric and after trying several things, the engine driven fan was the only thing to cure it.

		Because the cooling fan is ECU controlled on the 940 I also had to get a temperature sensor from a different vehicle.
		To install the fan on the radiator I had to cut the size of the shroud down quite a bit because the 940 turbo has a wider radiator than the 740.
		The fan was fastened to the radiator using stock mounting fasteners on the top and zip ties on the bottom.

	Electric Fan Install — Engine Cooling Tech - Custom Classic Trucks
		The advantages fans provide are that they work well in tight clearance situations, most have their own shrouds, they are available in various sizes, and they are very versatile in regard to mounting locations.
		With the fan properly centered using the scribed guide lines on the mounting-bracket surface, a 1/4-inch transfer punch was put through the fan mounting tabs and gently tapped with a hammer to make an impression on the mounting bracket.
		Once all the fan mounting tab location holes were marked with a transfer punch and hammer, a spring-loaded center punch was used to deepen the impressions made by the transfer punch.

		I used a 350 Camaro cooling fan along with some aluminum to bolt the electric fan to the factory cooling shroud.
		Instead of using a fuse for the power source of the electric fan, I used a 40 amp circuit breaker.
		To power the electric fan controller, I tapped into an existing circuit in the fuse panel.

	How To Properly Install An Electric Fan
		If you are installing an electric fan because you want more power or better cooling, you should read The Myth Of The Electric Fan before you continue, and make an informed decision on whether you want to go through with this mod.
		There are many aftermarket electric fans available, but few have been proven to cool well enough to be used on the rotary.
		The fan should turn on around 190 degrees or so in most cases as the thermostat is supposed to open around 177-183 degrees F. The fan should not fight the water-thermostat in maintaining temp, and should only run for a few seconds after the car is turned off (unless the car is very hot).

		With the engine and the fan running, you can put your hand on the ground in front of the rear wheel and feel the warm engine air that the fan is blowing out of there (and yes, I have both lower engine compartment covers in place).
		If you want the fan to function when you are away from the car, just hook the lead up to a source that is always hot.
		The only problem I've had is that the thermostat in the fan died and the fan just wanted to stay on all the time.

	2004 Ford F-150 Electric Fan Install - Project Dark Horse - Sport Truck Magazine
		The main reason for removing the belt-driven fan and installing electric fans is to reduce drag on the engine, which translates into more usable power to the wheels.
		However, by installing the dual 11-inch SPAL electric fans, we also increased the airflow to 2,780 cfm, which is 50 percent more than the factory belt-driven fan.
		Fans are available in 12- and 24-volt DC and 9- to 16-inch sizes, with straight or curved blades.

	Mustangmotorsport - Mustangs and a whole lot more!
		The last year that the Ford Mustang utilized a mechanical fan was in 1993 when the motor was cooled with a heavy blade fan and clutch fan which was bolted directly to the water pump pulley that was spun off the crankshaft.
		When the fan is activated initially, there exists a current spike in excess of 100Amps for a very short period of time (on the order of microseconds), and this is the reason why there should be a relay used that is rated at an amperage close to the spike.
		In order for the fan shroud to slide into the two metal lower radiator mounting tabs, the bottom bolt that was used to compress the overflow tab to the new shroud, had to have the bolt head grinded down very flat using a belt sander.

	Volvo Electric Fan Conversion
		With this conversion, the belt driven mechanical fan and fan clutch is eliminated, and the electric "puller" fan mounted in it's place.
		The plan is for the new fan shroud to be fastened to the radiator by four such screws, two at the top and two at the bottom.
		Should you still decide to go ahead with the conversion, this second link covers a lot of relevant information and some material on how to perform an electric fan conversion using a GM puller fan (behind the radiator, towards the engine), but much of the information is relevant to a pusher fan as well.

	Electric Fan Conversion
		This fan is intended to replace the belt driven fan that is stock on the engine.
		The stock fan is set up so that is will draw a sufficient amount of air through the radiator at low vehicle and engine speed to provide sufficient cooling.
		However, when the fan is engaged and the engine speed is dramatically increased as in full power acceleration, the fan will be spun much faster then needed and it can consume a great deal of power.

		Scrapyards were no help for 2 reasons; the first is that most cars have their front ends and hence the fans totaled and the next is that if you can find a fan the damn thing will set you back about R1200.
		Then I tried moving the entire fan closer to the radiator but that couldn’t work since the fan would interfere with the straps that hold the top and bottom ends of the radiator together.
		This was made up of the fans, temp switch, relays, fuses, marine ply, alu strips, belt, stainless steel cap screws and nuts and some electrical wire.
