Re: 2001 VW Passat leakin water
I would highly suggest a pressure test to really pin point this leak. I can tell from diagram that the coolant expansion tank line goes right thru that area. I would also caution you to the obvious with this vehicle- everything is a tight fit and coolant leaking from the t-stat housing and or water pump could look similiar. I strongly suggest a pressure test to keep from throwing good money away.

So far since VW started using phosphate free coolant (pink or red), I haven't seen the need to flush it. This depends whether it was mixed with tap water or other coolant. Anyway, there is a drain valve at the bottom left side of the radiator along the lower hose. Just turn it lefty lucy. Just make sure it isn't hot and pressurized or it will scald you, so open the reservoir cap first before you attempt on opening the valve.
NOTE: Make sure you use only VW G12 coolant and if you need to mix water, the best is filtered drinking water (reverse osmosis), not bottled but something like Brita.
