Radiator fan

Featured Replies

Anyone know what temperature does the fan meant to kick in ?  It works when the A/C on. I got the car temperature up to 94 degrees but can’t didn’t come on.

Which fan? The low speed should run whenever the a/c is on regardless of coolant temperature, but the high speed won't kick in until the coolant reaches more like 105C.

Mine does not run all the time whenever the a/c is on. I don't know what the parameters are for it to kick in.

Coolant temperature is usually sensed close to the radiator outlet in the context of fan activation.

On cars with traditional radiator-mounted thermoswitches the first (low) speed operation tends to be at about 95/96C at that point.

For the coolant temperature to be that high at the outlet, it will obviously need to be even hotter at the radiator inlet or engine head.

Not sure if your car has this type of thermoswitch,  or a sensor in an adjacent hose.

Probably the latter.

Depends on refrigerant pressure when A/C is on. In cold ambient temps this will not necessarily approach the threshold for fan activity.

I’ve only on fan, so just tying to work out if there something wrong with it as that code came up when I scanning tool
