I used a leak sealer to buy some time on the inevitable valley gasket replacement on my 2001 540i

OK, I admit it, I was bad my mechanic told me so and I used a leak sealer to buy some time on the inevitable valley gasket replacement on my 2001 540i. Now I want to do a very thorough flush of the system by running water through it for a while before having this job done to clear out the gunk that the sealer introduced to my system. Once I have drained and recycled the existing coolant, my plan is to: 1 connect a garden hose to let the water in and 2 disconnect a hose or open a drain plug to let it flow through the entire system before exiting. My thoughts are to let this flow continue for about a half hour or so to make sure it is as clean as possible. What would be the best entry and exit points for this flow? Any thoughts? Should I use an additive to help remove the gunk? Should I use warm water? Any photos or diagrams you could provide would be greatly appreciated. Thanks in advance - you guys run a great site!

I would remove all the hoses and flush each component separately. Radiator, heater, core, and engine. This will be your best shot at getting the sealant out.
