What are the components of a cooling fan?
What are the components of a cooling fan?
The operating components in the cooling fan circuit include the cooling fan fuse, relay, coolant temperature sensor and the computer. Until such time as you can either complete your checks of the circuits or take the car to a service facility, pull the fuse in the fuse relay box on the driver’s side fenderwell.
What to do if your cooling fan won’t turn on?
Pull the cooling fan relay out of the box. Replace the cooling fan relay with a new one. A stuck closed relay is the only thing that can operate the cooling fan continuously with the key off. The computer looses power with the key off and the same applies to the coolant temperature sensor.
What does it mean when your radiator fan is not working?
This is what we call a blown fuse. 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.
When does a computer turn on a cooling fan?
When the temperature exceeds a specific value — usually 215 degrees Fahrenheit — the computer will turn the fan on. The operating components in the cooling fan circuit include the cooling fan fuse, relay, coolant temperature sensor and the computer.
How to troubleshoot an electric cooling fan problem?
1.Has the Cooling Fan Actually Failed? 1 If the fan comes on when the AC is running at MAX, but doesn’t run when the engine is hot, check the temperature sensor… 2 If the fan fails to come on, first check for a fan blown fuse or triggered breaker. On older vehicle models, you may… More
What kind of fan does a Gen III GM truck use?
Many GM trucks equipped with a Gen III PCM use a mechanical fan. They use the typical high-speed-fan control output (red PCM connector, pin 33) as A/C automatic recirculation.
When does the cooling fan turn on on a Toyota?
The Toyota’s fan only turns on when the coolant reaches a certain temperature, which is measured by a sensor. This sensor switches the cooling fan off and on as needed.
What causes the fan with the resistor pack to overheat?
The fan with the resistor pack is the cabin fan and it us used to provide cool or warm air to the cabin. The engine overheating might be caused by a problem with the radiator fan. Can you separate those two fans and their related issues?
