What have you done to your mk4 (golf/bora) today?

Got a quick question on the radiator fans after doing a coolant flush ive noticed the fan dont come on once the car is at temp, they do when the ac is on and when the recirculation is on and also when I turn the car off just not when its running any ideas im thinking the sensor might be gone

i had similar issues recently, could be your switch, also make sure your thermo stat is opening to allow the hot water to pass by the switch. feel the hoses top and bottom of rad to confirm...

Yeah both hoses are hot and the heater is blowing hot air so the heater core is working also the coolant is flowing back to the expansion tank, im really hopeing that means its the sensor

I am currently not having the fans come on at all ....

so today, replaced old fan with a new fan



Problem is, still not turning on at all. So next stop is a new cooling fan relay ....

Whilst I was busy on the car, fitted the new bottom front spoiler I had sitting in the garage for a month or 2 ....

I was tidying up the shed and came across my lamda sensor tool, and thought hey that looks like it could fit the strut top nut. I could not torque it correctly when i replaced the struts recently.
Allen key through the middle, torque wrench at 90 degrees and it worked a charm.
And 44 ft lbs is not a lot.

Here is the tool

Hey sharkie, if you check through the forum there is a section on mk4 AC and fan issues. I think there are some links in my build thread. If you have no luck pm me, I have a lot of saved links....

Thanks mate, all fixed .... forgot to change the fuse (on top of the battery) that blew as a result of the fan motor issue discussed in that thread.

Worse, I ordered the fan controller already .... oh well another spare won't hurt
