Can an auxiliary fan be used as a cooling fan?
These are Flex-a-lite electric fans designed to be used as auxiliary cooling fans, mounted in front of the radiator, to help a belt-driven fan with additional airflow through the radiator at idle or slow vehicle speeds.
What does an AUX fan do?
In a nutshell, an auxiliary fan supplements the airflow and cooling that is provided by the belt-driven fan. It will be essential in drawing the extra air that is needed by the engine, especially when you are moving slow.
Can you run a pusher and puller fan?
Can You Run a Pusher and Puller Fan? Yes, you can technically run a pusher and puller fan in conjunction. Because of that, the mechanical fan can only pull so much air through the radiator at idle and low speeds, making an additional pusher fan a useful addition.
When do you turn on the engine cooling fan?
So, extra cooling is not needed, when a cold engine is first started. As a result, the engine cooling fan, does not come on until the engine reaches, normal operating temperature. The fan will then cycle on and off as needed, to maintain the proper coolant temperature.
When to turn on the cooling fan relay?
The cooling fan relay is an electromagnetic switch that controls the power supply to the engine’s cooling fans. It ensures that the energy-intensive devices only run when needed, usually when the vehicle is immobile. When the engine temperature approaches unsafe levels, the vehicle’s computer or temperature switch turns on the cooling fan relay.
What do you call an auxiliary cooling fan?
-Michael Harding, June 2017 A couple of decades ago, it was popular to simply add a switch under the dash to control an electric cooling fan, often referred to as an auxiliary fan. This was a mediocre way of doing things, primarily because the current required to spin the fan was drawn through the switch itself.
What should the temperature be for a fan to shut off?
The temperature sender, if used, is designed to provide a ground signal at about 185 degrees, and will shut back off when the temperature drops below 165 degrees. This wire (gray in our kit) supplies the ground signal to trigger the relay.
