Engine cooling fan active at start of engine

[Invité gronbek]

Hi,

 

Sorry no French speaking

 

On my new C4 2.0 VTR the radiator coolant fan is starting when I start the engine. Even when it is cold. This is strange to me. Should it not start when the engine is hot?

 

Thanks, Anders

Hello Gronbek,

 

is it warm outside ?

 

On my car it isn't always active, only when the engine is hot.

 

My engine is a 1400 16v gasoline

Its about 15 degrees celcius outside.

And the fan start when I start a cold engine.

Thanks,

 

Anders

Air conditionning at start, maybe ??

[Invité gronbek]

Yes, Air condition is on at start.

Is that the reason for the radiator fan running when starting engine?

I thought the coolant fan on the radiator only purpose was to cool the water when the engine is running hot.

 

Thanks, Anders

Hi,

Is fan always running or it stops few minutes after starting ?

Try to start without A/C ; fan should be off.

[Invité GG1975]

yes I confirm the problem is: you start the car with A/C on.

You have to know that A/C radiator is VERY hot, and it gets hot VEEERY fast!

Engine coolant reaches 100 degrees, AC gas is hotter thats why fan is always on when u start AC.
