When does a Gm F-body coolant fan engage?
The coolant fan does not engage until 222°F or higher (depending on year and engine). It’s been shown that at these high temperatures, air and fuel burn more completely and therefore producing less hydrocarbons. However, these temperatures severely reduce engine life and kill performance. So why not just install a lower
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.
How does a rear wheel drive radiator fan work?
This type of fan is used in both front and rear-wheel-drive cars. Activated by a coolant sensor via the computer, the coolant sensor is in charge of monitoring the temperature of the engine’s coolant. If you have coolant sludge, then this is a sign of a broken radiator that might need replacing.
What happens if you cant turn the radiator fan?
If you can’t turn the fan blade, then the clutch has locked, or there might be an excessive movement that is erroneous to the function. If any of these cases hold true, then a replacement of the radiator fan is required.

What happens if a radiator fan burns out?
If the cooling fan motor burns out, the cooling fans will then, in turn be disabled. Since the cooling fan motors work in tandem with the fan blades to pull air through the radiator, the blades will then not be able to spin or cause any airflow to cool off the car.
What should I do if my radiator fan is not working?
A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.
Is there a way to test a radiator fan?
You can test the electrical radiator fans by taking a wire from the car battery, unplug the radiator fan connector, and put 12v+ and ground into the connector. This is the fastest and easiest way to test your radiator fans. Because the radiator fan is often drawing so much power, there is often a relay that is powering the coolant fan.
