You've got all the info you need, if you can't work it out then there's not a lot of options shot of a mechanic.

so the fan isnt always on? on works at a certain degree the engine is at?

correct, it isn't supposed to be on all the time, just when it feels it needs to be.

Found out today that I have a dead fan switch. While I'm waiting to get the part in, is it ok to just short out the fan switch connector so that the radiator fan is on 100% of the time?
Also when replacing the fan switch, will I need to drain all the collant fluid out of the system first?

Keeping the fan on 100% of the time is fine as a short term solution. It wont damage anything, though the engine may run slightly colder than usual. You'll have to drain the coolant too.

I took the radiator fan switch out today and tested it and it was actually working fine. I boiled some water, suspended the probe above it and when the water was reaching its boiling point, the switch activated. So now I'm a little confused as to why my radiator fan never turns on?? Is it beacause the weather is cold at the moment? I don't get overheating issues, but I've only had the car for about 3 weeks.

I leave the car to idle for over 10mins and the engine gets warm, but my temp gauge reads "normal" and fan doesn't turn on (despite the service manual saying the fan should turn on at least twice in the 10min span).

I've tested the fan by hooking up power to it and it spins, I've tested the relays and all working ok. Fuses are all ok as well. If I unplug the radiator fan switch and short out the connector, the fan turns on so I thought it was the switch problem, but turns its not? Where to go from here....

the fan will only turn on if it detects your car getting too hot.

the fan will only turn on if it detects your car getting too hot.

Yea I know that..it turns on when it detects temps of 91-95 degrees celcius. But my question is how long does it take for the coolant to reach those temps under normal idling and air temps we are experiencing lately (approx 14 degrees air temp). I thought that idling the car for 10mins would cause the fan switch to turn on. Perhaps I should rev the car to 3000rpm and hold it there to bring the heat up more?
