At what temp should my fan kick on?
about 200 degrees Fahrenheit
Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.
Why is my clutch fan not engaging?
If your fan clutch is not operating the way it should, it’s likely due to a fluid leak or a bad thermostatic spring or valve. This premature clutch engagement means the fan spins faster than it should, but that doesn’t make the engine or a/c run hot.
Can a bad fan clutch cause an AC to not work?
The guy calls back and says the fan clutch for the radiator is bad. He can run a hose on the radiator and the air is cold but the truck doesn’t over heat. Does that sound right to anyone? Why wouldn’t the engine over heat if the fan wont spin, and why would this problem cause the ac not to work?
How can you tell when a fan clutch is engaged?
You should be able to audibly detect when the fan clutch engages, with an accompanying rush of air. At idle, as engine temperature increases, a thermal fan clutch will engage at a certain temperature. Torque-limiting fan clutches will disengage at a certain engine speed. Alternatively, an optical tachometer can be used to measure fan speed.
How does a thermal fan clutch work on a car?
When the fan clutch engages, it spins up greatly, increasing air flow through the radiator and over the engine. A thermal fan clutch reacts to temperature of the air rushing over it from the radiator. As the radiator heats up, the air passing through it also heats up.
Is there a bad clutch on the radiator?
No A/C…Bad fan clutch??? Ok, so I have an 06, 6.0 and the a/c wont blow cold so I took it to a shop. The guy calls back and says the fan clutch for the radiator is bad. He can run a hose on the radiator and the air is cold but the truck doesn’t over heat.
