If you are adding an electric fan to your ride, you can First things first. If your engine is designed to run at 200°F, a 14-16-pound cap should be sufficient. Contact . Pusher-style fans mount on the front of the radiator and blow air through the radiator core. For example, on a '32 Ford, the area of a 15.50" fan is about 189 sq. 9. drive. 10. Running a higher pressure cap to prevent boil over is putting a band-aid on another problem that needs to be fixed. /* RT66-Link120x90 */ 8) Overdrive the water pump 20-30%. Primary electric fans (pullers) are designed to mount behind the radiator and replace a factory belt-driven fan. google_ad_slot = "6369798871"; and provide less wind resistance. This overdrive provides proper coolant flow from the engine and through the radiator. A pusher-style fan can be used as an auxiliary cooling source, but you should sure make the fan covers as much of the radiator … A 50/50 mix of coolant and distilled water provides the best overall cooling efficiency. A manual fan is connected to the engine drive pulleys and is controlled by a thermo fan clutch which senses radiator heat and engages when the engine is running at higher temperatures. 4. To answer this, it seems like the consensus is in favor of the pull style fans. Selecting the right thermostat for your engine's operating temperature range means better performance and longer life. Mechanical fans operate off of the engine's power and are usually connected Higher operating pressure places additional stress on the entire engine system and increases the potential of hoses bursting and possible injury. designs to address these issues: - these fans have flexible blades that as engine rpm increase, the blades flatten out Contact . This means that the fan is only on directly to the front of the water pump. the vehicle was running on the road. The thermostat controls engine coolant temperature. Fan #1 turns on first and if the temperature rises past a second set point, then fan #2 turns on to increase the cooling. the 12V at their terminals or physically reversing the fan blade. You must consider how the heat will be evacuated from the engine compartment. It allows you to turn your thermostat up a few degrees. If the fan is mounted between the engine and the radiator, then it is a puller, if it is mounted between the radiator and the front bumper, it is a pusher. //-->. You need sufficient openings to the radiator that channel adequate air to the entire surface of the radiator. During 90% of the time, the fan free wheels and takes a minimal amount of energy from the engine. Likewise, if the blade is angled down and the fan turns the opposite direction, the reverse is true. An unshrouded fan is moving air through only the portion of the radiator equal to the surface area of the fan. Should cooling problems persist, it may be time for a new performance radiator from Griffin. It is a setup where the radiator is sandwiched between 2 sets of fans, which blow in the same direction. /* RT66-Link728x15 */ The Intake-exhaust direction should go front-to-back and bottom-to-top. Legal | Privacy. when it is needed. 4) Check your radiator cap. Your order may be eligible for Ship to Home, and shipping is free on all online orders of $35.00+. Another issue is that at high rpm, there could be the larger the CFM rating of the fan. The Rear or Exhaust side (the side that the air comes out of) of our fans will always be the side that houses the fan motor. This means that it is This means that almost 49% of the unshrouded radiator is not receiving any benefits from the fan. A puller fan on the other hand sits right behind the radiator. the clutch engages and the fan starts turning. If a blade is angled down and the fan turns in the same direction as the blade angle, it will blow forward. You may You will also be able to identify the Exhaust side as you will see power wires entering the fan motor. Fans that move 2000-2300 CFM's are worth the investment. //-->,
