Why are both radiator fans supposed to work at the same time?
One of them is, and one of them is not. Obviously if the car is designed for two fans to run at once, then it’s not getting enough airflow at standstill and that causes my car to overheat. But if it is supposed to be that way, that means it’s something else. 1986 Chevy K20, 350 4×4 on Megasquirt. Brings the car home when it breaks. Future cars?
When does a high speed fan kick on?
Cooling fan motor testing (low and high speeds), relays, harness connectors…it’s all here. Generally, the low speed fan kicks on when the A/C is turned on or when the coolant temperature hits around 200 degrees F. High speed kicks on around 220F. This video is being performed by an experienced tech.
Can a stuck relay cause a Rh fan to run?
No relays are “stuck on”. There’s only one that could stick on, and cause the RH fan to run, but it would run at all times, regardless of key on or off. It doesn’t, so it’s not a stuck relay. The ECM grounds the dk grn wire for low speed (one relay), and the dk blu wire for high speed (two relays).
Is it worth it to get a Honda fan?
Do it for Cheap- don’t make it cost more than it has to. Do it Yourself- It pays off in Knowledge, Skills and Abilities. Pass these skills to the younger generation! They need them now!
What kind of ceiling fan is big air 96 in?

How many blades does a big air fan have?
REVERSIBLE FAN: It has 9 blade designed for high volume air movement and rotates in reversible direction for changing seasonal needs and has remote controlled operation – functional for multiple fans at one time. BIG AIR FAN: DC motor is energy efficient and ENERGY STAR and has convenient wall holder for remote storage. It is for indoor use only.
Why does my Dell Computer have more than one fan?
Your Dell computer may contain several fans to keep the internal components cool: Desktop computers have more than one fan – processor (CPU), dedicated or discreet video card (GPU), power supply (PSU), and one or more chassis (case) fans. Laptop computers may also have more than one fan and may vary between different models.
Which is better big air or ICF fans?
BIG AIR FAN: DC motor is energy efficient and ENERGY STAR and has convenient wall holder for remote storage. It is for indoor use only. These new ICF fans save on operating costs with energy efficient DC motors. They save up to 65% more efficient than traditional AC fan motors.
How does a condenser fan work with a radiator fan?
The condenser fan relay provides power to the condenser fan. Both fans ground receive ground at G109 located on the right radiator support. If the radiator fan relay is activated and the ECM detects that the fan can’t provide adequate cooling, it will activate the condenser fan relay to provide supplemental cooling.
What should I do if my radiator fan is not working?
If the radiator fan relay is activated and the ECM detects that the fan can’t provide adequate cooling, it will activate the condenser fan relay to provide supplemental cooling. If both fan can’t provide enough cooling and the temperature gauge rises into the danger zone, stop driving the vehicle and have it towed to a shop.
Where does the ground come from on a Hyundai radiator?
The ECM then provides ground to the control coil on the condenser fan relay. The condenser fan relay provides power to the condenser fan. Both fans ground receive ground at G109 located on the right radiator support.
How does a radiator fan work when the AC is on?
The electric radiator cooling fan assembly is controlled by a thermoswitch located in the side of the radiator. At higher coolant temperatures, the switch closes to start the cooling fans. Any time the coolant temperature rises to higher than normal levels, the fan will start and continue to run until coolant temperature returns to a normal range.
Do you have to run radiator fan all the time?
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? To avoid a further rise of temperature, the fan induces air flow.
Where are the pusher fans on a radiator?
Many of the fans are electric. The electric radiator fans mounted in the front of the radiator are known as pusher fans. Those located at the rear of the radiator are called puller fans.
How many blades does a radiator fan need?
The cooling fans, with between four and eight blades, spin rapidly to provide cooler air to the engine. The fans do not work alone. They are part of a larger overall cooling system in the vehicle. All of the parts need to be working correctly for the fan to be able to do its job and cool the engine.
