Do you turn the radiator fan on or off?
Do you turn the radiator fan on or off?
The coolant temp has to be hot for the fan to come 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.
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.
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.
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.

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??
