When should your radiator fan come 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.
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.
Why is my radiator not working when the AC is on?
I checked it while it is on cold state, but then when turn the AC ON the Radiator Fan turn on, so I let the AC ON while i drive my car, after 30mins driving if i turn the AC OFF, the RADIATOR FAN still dont work, even the Radiator Temp was hot. The coolant temp has to be hot for the fan to come on.
Is the fan supposed to be on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. Both radiator fans should always run when the coolant temperature sensor in the bottom tank of the radiator reaches about 212*F. Click to see full answer. Similarly one may ask, is the fan supposed to be on when AC is on?
Can a convection fan be used to cool a radiator?
If it’s cold outside (but not so could that it would prevent using the A/C), natural convection should cool the radiator adequately. Well the short answer is yes. The A/C requires the fan to run as part of the heat exchange process. The A/C runs on a separate circuit and is triggered by A/C system.
Can a radiator fan be turned on when the a / C is on?
Yes, the fan will come on when you turn the A/C on, so that proves the fan works. Leave the A/C off for the rest of the test. Start your vehicle, and let it idle for 10-15 minutes. Depending on the ambient temperature in your location, this should be long enough for the coolant temp to get hot and the thermostat to open up.
When does the fan turn on when the AC is off?
What a nightmare. The fan is automatic, depends on the coolant temperature. That is when the engine is running while the AC is off. Then the radiator fan will turn on when the engine is warm enough. But when AC is turned on, even the engine is icy cold, both fans turn on immediately, am I right??
Why are my coolant fans not turning on?
If both fans operate then it is time to take a look at the pressure transducer. Don’t let this strange name fool you, it is simply a sensor that relays the amount of pressure in the system to the PCM and the PCM decides when to turn on the fans and or compressor clutch.
How often should my radiator fan come on and off?
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?
