    Quick Service On The Correct Fan
    This fan was purchased and installed on my 2003 VW Passat Wagon. This was the third vendor I had tried for this part. The first two vendors sent a fan whose electron motor was significantly larger than this one (the motors on those fans were much "deeper", or said another way, the motor extended back from the fan blade much further). This product arrived quickly and looked exactly like the one shown in the picture. The connector from the fan fits to the cable running to the fan control module. In addition, the fan fits nicely onto the rectangular fan assembly–the bolts were exactly where they should be. I have, now, used the fan for about two weeks and all is well. The fan comes on and runs as expected.
