All of Hayden's Electric Fans feature:
As a primary cooling source our electric fans provide:
As an add-on cooling source our electric fans provide:
Our 12V dual fan kit contains two, twelve inch, Thin-Line fans on an adjustable bracket. Typical application is supplemental cooling on G.M. and Ford powered class “A” motorhomes.
Performance Electric Fans. ULTRA-COOL 14” and 17" fans offer the highest airflow outputs in a very low profile. Under 3" thick they fit a wide variety of primary and supplemental cooling applications including cars, trucks, SUV's and custom vehicles. The unique design allows the fans to be installed as either a puller or a pusher without having to reverse the blade or wiring. A powerful 130/270 watt two-speed motor provides high airflow even with thick or dense radiators. Four Mounting Hardware Options Included: Adjustable ratcheting mounting system, Direct mounting through radiator, Radiator frame rail mounting, Angle bracket mounting.
The "DAWG" is the perfect transmission cooling system when space is a limitation and "RAM Air" is not readily available. The unit provides maximum cooling protection in all conditions. Whether mounted as a conventional transmission oil cooler or remotely placed on the vehicle, the transmission is continuously protected.
The combination of a "high-flow" electric fan, and either a high performance cooler or plate style cooler, gives every consumer one of the most economical and effective add-on cooling products ever introduced.
The "DAWG" can be manually controlled with an optional switch or by using our electronic fan control, part number 3651 (not included) to provide automatic operation when cooling is needed. The unit is perfect for the every day consumer, or gives the experienced owner the ability to use installation parameters with VERY specific objectives.
Ideal for motorhomes, offroad vehicles or light trucks and SUV's, this unit will provide added peace of mind knowing your vehicle's transmission is protected by the number one name in cooling products, Hayden Automotive.
Over 14 million transmissions fail every year, 9 out of 10 from overheating. Every 20° drop in operating temperature can double oil and equipment life. Use a transcooler if you:
Ultra-Cool® Transmission Oil Coolers. The industry's first transmission cooler, the Ultra-Cool® transmission oil cooler is available in six sizes to fit a wide range of applications from sub-compacts to motorhomes.
Rapid-Cool® Transmission Oil Coolers. Rapid-Cool®’s unique plate and fin design offers excellent cooling efficiency in a compact, space-efficient design.
Rapid-Cool ® Heavy-Duty Transmission Oil Coolers. Hayden’s 37mm heavy duty plate / fin coolers are ideal for Transmission and Engine oil cooling applications requiring higher flow range and increased heat transfer capacity in a compact space.
High Performance Transmission Oil Coolers. Available in three sizes for medium to heavy duty applications, our high performance cooler is designed to provide outstanding cooling, as well as to complement other high performance accessories.
Remote Transmission Oil Cooling Systems. Our remote mount cooling systems use the most advanced stator fans to evenly distribute airflow over the cooler surface for maximized cooling. Both units can be remotely mounted away from the radiator. Compatability with model 3651 adjustable fan control, or can be operated with a manual switch (not included).
Power Steering Oil Cooler
Our power steering oil cooler removes destructive heat generated within a power steering system, especially in vehicles with large tires such as, motorhomes and off-road vehicles. Installation of a power steering oil cooler will prolong the life of the system’s pump, hoses, and seals.
Ultra-Cool® Engine Oil Coolers - Light Duty
Ultra-Cool® Engine Oil Coolers - Medium Duty.
Swirl Cool® - Heavy Duty
Most of today’s vehicles use Idler Pulleys to assist in belt routing and tensioning within the accessory drive system. Air conditioning compressors, alternators, power steering pumps, and water pumps are aided by the function of Idler Pulleys. All Idler Pulleys are of the highest quality and meet or exceed OE specifications.
Over 100 million vehicles on the road today use a belt tensioner. Belt tensioners maintain constant tension on the belt to extend both belt and accessory drive bearing life. We offer a full product line covering most domestic and import vehicles. All our belt tensioner assemblies are original equipment quality for long life and easy replacement. Refer to the following application section for the correct belt tensioner assembly or replacement pulley for the tensioner.
Fan Clutch Operation & Troubleshooting
The Fan Clutch is a component of the cooling system that varies the fan speed to meet the cooling needs of the engine. Nearly all rear wheel drive vehicles use Fan Clutches to control fan speed because of their ability to provide high volumes of air and good fuel economy. Despite their popularity, they are one of the least understood cooling components. There are two types of Fan Clutches, the Non-Thermal (also called centrifugal clutches) and the Thermal Fan Clutch.
Non-Thermal Fan Clutch
Thermal Fan Clutch
The air temperature coming through the radiator is sensed by the bi-metal thermal spring on the front of the thermal fan clutch. It expands and contracts with the change in air temperature operating a valve inside of the clutch. When cold, the silicone drive fluid is pumped from the working area to the reservoir. When hot, the valve opens allowing fluid from the reservoir to be transferred to the working area thereby increasing the fan speed. The clutch disengages as the air temperature decreases, closing the valve and allowing the silicone fluid to be pumped back into the reservoir.
A thermal fan clutch is engaged on a cold startup because the fluid drains into the working area when the engine is shut off. The fan clutch will slow down shortly after startup as a result of a pumping action produced by a difference in speed between the shaft and the body of the clutch.
Most models are designed to duplicate original equipment performance. Some Chevrolet/GMC truck models are specifically designed to engage at lower temperatures than the original equipment parts that they replace.
Thermal Fan Clutch Design Types
We make three different types of thermal fan clutches; Standard, Heavy and Severe Duty. 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. Use of the wrong fan clutch may result in poor cooling, excess noise, reduced mileage, or fan clutch failure.
Standard Duty Thermal
Severe Duty Thermal
Hayden now has available Truck Fan Drives for Ford and General Motors medium-duty trucks and buses.
