My 2001 volkswagon beetle is over heating the fan isn't moving
The temp warning keeps going off, the first fews times I couldn't see anything that was wrong, now it is very hot and there is a slight whistle noise like a tea keetle, but there isn't any fluids coming out.

Check your fan clutch- is it engaging when idling and at op temp if not then chances are the clutch is bad.
Replace your thermostat it's usually a cheap and easy fix
it just sounds like you have enough air going through into the engine compartment to cool it down but when you have no air going through at idle it heats up which leads me to believe it's something to do with the clutch fan or thermostat.
How much more does it heat up at idle as opposed to driving on the highway? check your thermostat ratings if possible i believe my firebird's thermostat is rated for 195 degrees. If the engine temp is exceeding the temp your thermostat is rated for then something else is going on.
Always look for the small things first and replace them if you need to before replacing anything big like the water pump which isn't too hard but is time consuming. Hope this helps. Good luck.
I have a few beetle ( vw and audi too) customers who are regulars for headlamps. I first had this problem on my 96 audi a4 and I came up with a simple solution If you have fog lamps leave them on all the time. my headlamp failures went way down when I did that.
Try this if you have fog lamps, my customers did not have fog lamps so they could not try it.
Hope this helps, it it does please leave feedback and vote Thank You and Good Luck
If all those items are good then you have to test the following items :Low pressure switch , compressor clutch and refrigerant quanity,pressure and restriction free circulation (any icing on the lines).
