cooling fan
 

Hi all I have a question,could somebody tell me when the cooling fan is supposed to cut in,only I ran the engine for about 1/2 hour after changing the fan motor(the one in the car packed up and I only noticed when the car overheated in traffic)the temp stayed at normal,but the fan does not cut in,but when I press defrost it does work?the car is 1.8 turbo 52 plate,and the motor is three wire.Only all other cars I've had the fan cuts in after some time because the engine is getting hotter as it is running.There are no leaks either??. Many thanks in advance all.

On your engine Alan, at 104°C.
I'm not surprised in the current cold weather conditions. You'll need to drive the car to put the engine under load to generate some heat. Monitor the actual coolant temperature using the instrument pack diagnostics.

When you said--"stayed at normal" you probably meant the 9 o'clock position on the gauge. This can range from 80 to 100 degrees plus WITHOUT moving.---:eek:

Ignore the gauge and do as in post above.--:D

Many thanks Cheers

Fan failure is quite common on 75/Zts. For example I'm on my third (Revotec) and my car has covered 125000miles. Original fan lasted 60000miles and the Kenlowe was not much better. To test the fan switch the ignition onto the second position (engine does not need to be running) and switch the screen demist button, and the coming fan should always spin. Search out posts in the Technical Forum on cooling fan issues - there are lots of them. Jules in North Wales is a guru on cooling fans.

Correction
 

That is true for your diesel Big Al., but not for the OP's 1.8T. His engine must be running for the fan test which he doesn't need to do anyway because he's already done it! (see his first post).

Hi Simon.
Does that relate to my V6,

Cheers.

Yes Julien. All the petrol engines need to be running when carrying out the 'demist' test.

Cheers Simon, having two diesels on a learning curve.
