Fan isn`t working please help!!

[Yolo_8p3]

ok so i need some advice my fan isn`t working its a a3 2011 1.6 tdi the full rad pack was removed and refitted and before i disconnected the fan pack they were fine but now since re-plugging them back in its(only 1 big fan)not working at all and even though the temp is still on normal its getting pretty hot under there...

any ideas what to check?

Diesel fans take years to kick in if your just letting it stand ticking over,one works on engine temp the other works with the aircon,but i cant remember if when you put the aircon on if they both jump in to action,without been stupid how do you know its not kicking in and do you know what point it kicked in before ? we have to leave them running for hours to get the temps up in diesels and even taking them a run you'll struggle to get them to over heat,maybe take it for a run get temps up and then let it stand ticking over but this again isnt that good for the car neither.

i picked the car up from garage yesterday and drove like 22miles home the temp didnt go over half but when i got back home to check the water and oil under the bonnet was extremly hot and you could barely touch the plastic cover of the engine so then i tried my ac button and the fan wasnt still working weird how i only have 1 large fan ?

Cars do get warm under the bonnet mate ,but if the temprature is normally around 90 for normal driving if it starts going above 95 etc thats when the fan should kick in,i dont know how many fans it should have but i thought they all had two from memory but i am probably wrong ,is the aircon working ? i would ring up and just mention your concerns maybe ?

cos its a 1.6 tdi i assume that's why its got 1 fan but the fact that it was really really warm under there gets me a bit worried that i may cause damage cos of the fan not kicking in and when the car is running the fan used to work immediately but now its nothing

In nearly five years of ownership my fan never kicked in even on hot days and after long drives. Mind you it's 2.0 TDI.

Does anyone know where the thermostat plug is cos if I loop that it should work

 

[Yolo_8p3]
