There is an electrically operated clutch on the input shaft of the compressor. Although the pulley spins all the time, the compressor should be running only when called for. The possibility remains that there is something wrong with your system and the clutch is engaged all the time. If you can feel the compressor kick in and out when the A/C is running (you should feel the idle speed change) then this is a certain sign that the system is working properly and there is no real need to remove the belt in the winter. If you take a look at the edges of the holes where the belt passes thru the pulley housing, I think you will see that these edges are cut somewhat roughly and were not painted after cutting. This would be what I would consider signs of a "non-factory" installation. The fact that these hole are "small" needs to be considered along with the fact that they are right above the exhaust system and the fact that there is a considerable amount of vacuum in that housing when the engine is running at speed. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Pitch in!
