How does an electric engine cooling fan work?
An electric fan operates independently, controlled by a switch at the engine thermostat. These fans are usually lighter, and they release energy drained by mechanical fans or fan clutch systems, giving a clear performance benefit and more effective cooling. What does the fan include?
When to use electric or belt driven fan?
The electric fan would be a cooling solution for vehicles that typically drive at low vehicle speeds with low engine rpm, such as cruising. If you have a 4-core radiator or towing heavy loads then we recommend you stick with a belt driven fan. Finally, if you have a cooling problem, watch this blog for future articles that will help.
How many CFM does an electric radiator fan need?
Summit Racing carries a huge selection of electric radiator fans to complete your cooling system upgrade. Cooling fans are categorized by cubic feet per minute (cfm) ratings. A general guideline to follow for cooling a stock engine is 2,500 cfm for an 8-cylinder, 2,000 cfm for a 6-cylinder, and 1,250 cfm for a 4-cylinder.
How big of a cooling fan do I need for an 8 cylinder car?
A general guideline to follow for cooling a stock engine is 2,500 cfm for an 8-cylinder, 2,000 cfm for a 6-cylinder, and 1,250 cfm for a 4-cylinder. Of course, high-performance engines require more airflow. Many electric cooling fans are rated by recommended horsepower to help you choose the optimum cooling fan for your vehicle.
When does the cooling fan come on or off?
I’ve read that the cooling fan will run the whole time when either the A/C is on or the vent control is set to defrost, regardless of whether the engine is cold or hot. In my case, the cooling fan comes on when the engine is cold, even with the HVAC off and it will remain running at full speed when the engine is running, again with the HVAC off.
How often should my radiator fan come on and off?
An electric fan SHOULD NOT run all the time. A mechanical fan WILL spin as long as the engine is running, but it will only ‘lock up’ when needed. Furthermore, why does my radiator fan turn on and off?
Can a mechanical fan keep an engine cool?
Mechanical fans rely on engine rpm and when sitting at idle, they just don’t spin fast enough to keep your engine cool. Mechanical fans also rob your engine of horsepower and fuel economy since they are driven off the crankshaft.
What’s the best speed to run a cooling fan?
A. Generally, cooling fans do the most work at idle and speeds up to 35 mph. The faster the vehicle is moving the less important they become. At speeds over 35 mph, the ram air effect is much great than the efforts of the fan.
