Does the fan cool the engine?
Your car’s cooling fan, or radiator fan, plays an important job in keeping your engine cool. If it stops working, your engine could overheat and be damaged.
Can an electric fan cause an engine to overheat?
Engine overheating: A bad radiator fan can cause the engine to overheat, especially at low speeds. If your car starts overheating, pull off the road as quickly as you safely can and turn off the engine.
How can I improve my engine cooling?
Let’s dive in.
- Increase flow through the cooling system. The flow through the cooling system can be increased by installing a water pump impeller designed to increase the flow rate of the coolant.
- Increase the cooling capacity of the radiators.
- Increase the pressure of the cooling system.
How much horsepower does an electric fan add?
In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a maximum of about 5 horsepower from the engine. This significant savings improves fuel economy, and, in turn, reduces emissions while improving vehicle performance.
Does the fan cool the engine or radiator?
The radiator fan (or fans) pulls cooling air through the car’s radiator. Positioned between the radiator and engine, cooling fans are particularly helpful when the car is stationary or moving at speeds too slow to force air through the grille.
Why is an electric fan better than mechanical?
An electric fan completely removes the mechanical load of spinning the fan from the engine. It places an additional draw on the electrical system, but this is a more efficient means of spinning a fan, and it has a smaller impact on engine drag. An electric fan can cycle on and off, reducing the electric load.
Why is my engine cooling fan so loud?
One such problematic issue, the excessively loud radiator cooling fan, is a common plague many automobile owners will experience. Your radiator fan should be audible. Worn bearings, bent or broken blades, and unbalanced rotating assemblies can cause a fan to screech, howl, or otherwise make noises it shouldn’t.
What tells the cooling fan to come on?
The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees. You may have heard of a part called the radiator fan switch or temperature fan switch. This is linked to a thermostat and works much like your home’s HVAC system.
How do you fix high coolant temp?
What to Do When Your Engine Overheats
- Kill the A/C and crank the heat. Immediately turn off the air conditioner to reduce stress on the engine.
- Find a safe place to pull over. Pull over and shut off the car.
- Check and add coolant (if you have it).
- Restart the engine.
Can I pour water on my engine to cool it down?
No, Do not pour cold or still water into a hot radiator or engine — it could cause the engine block to crack due to the sudden change in temperature. This phenomenon is known as thermal shock.
How many CFM do I need to cool my engine?
As a general rule of thumb, follow these minimum cubic feet per minute (cfm) ratings when using an electric fan as the primary cooling source on a basic engine: 1,250 cfm for a 4-cylinder. 2,000 cfm for a 6-cylinder. 2,500 cfm for a 8-cylinder.
What is the main advantage of having an electric cooling fan compared to a directly driven fan?
A key advantage of electric fans is increased engine cooling and improved air conditioning cooling at idle, when it is most needed. In addition, replacing an engine-driven fan can increase horsepower and improve fuel economy as the engine drag from turning the fan is eliminated.
Are dual electric fans the best option for cooling your car?
As many of you know, clearance between the front of your engine and radiator can be very tight. Most of the time your first thought is to find the slimmest single electric fan possible that’s powerful enough to cool your car, but wait, there’s a second option! Dual electric fans could be the solution to your cooling issues.
Do electric cooling fans keep cars cool at stop lights?
For some, however, electric cooling fans are not only keeping the engine cooler in traffic, but they keep the engine cool at stop lights, too. Mechanical fans only cool as much as they can based on the engine speed, but electric fans draw the maximum cfm at idle because they operate independently of engine rpm.
Can you use a mechanical fan for high horsepower?
Using a mechanical fan for a high horsepower application can work just fine if a couple of things are considered. A larger radiator, a larger clutch-fan, and a shroud would probably keep your engine cool; mechanical fans can sometimes work better than electric fans.
How do you install a mechanical fan with an electric fan?
The first part of the installation is to install the electric fan to your radiator, and remove the mechanical fan. It’s unlikely you would have room for both, but you should never run a mechanical fan with an electrical fan on the same side of the radiator. If your mechanical fan had a fan spacer, it can be removed with the fan.
