electric radiator fan air direction

Contact . Higher operating pressure places additional stress on the entire engine system and increases the potential of hoses bursting and possible injury. Presenting another universal but budget-friendly model- … Likewise, if the blade is angled down and the fan turns the opposite direction, the reverse is true. You must consider how the heat will be evacuated from the engine compartment. When a vehicle is moving, a pusher fan can obstruct airflow due to its positioning in front of the radiator. Fans that move 2000-2300 CFM's are worth the investment. These are usually the factory location for electric fans. Slipping belts or collapsed hoses mean trouble. You need sufficient openings to the radiator that channel adequate air to the entire surface of the radiator. pull air through the radiator from the front of the vehicle into the engine compartment. . Consider the investment compared to the total cost of the car. We’ve made it simple to start. Consider the investment compared to the total cost of the car. 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. However, some longitudinal (front to rear) mounted engines use the electric fan as well, but they usually have an engine-powered cooling fan. Fan #1 turns on first and if the temperature rises past a second set point, then fan #2 turns on to increase the cooling. It is very easy and inexpensive to update a fixed blade fan to a flex fan. $9.99 shipping. when it is needed. Higher operating pressure places additional stress on the entire engine system and increases the potential of hoses bursting and possible injury. Use the proper water pump pulley ratio. There will be a temperature sensor that when it reaches a preset temperature the fan will turn on. and provide less wind resistance. 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. You can easily tell when the clutch fails, the clutch seizes and the fan turns constantly - your engine becomes unusually noisy! A fan without a shroud is better than no fan. The result is a slow oscillation of the temperature gauge reading. 8. With a pusher fan, air would push out from the edges - reducing air velocity into the front of the radiator. An unshrouded fan is moving air through only the portion of the radiator equal to the surface area of the fan. 10. 99 percent of all stock cars are puller fans that pull air through the radiator. //-->,
