When replacing a radiator, does cooling system need to be flushed and bled?

What is your question?

I had to replace a leaking radiator on my 2011 BMW 528i. In addition to being charged for a new radiator, I was charged for 1. Bleeding the cooling system (0.50 - $90) 2. Flushing the cooling system (1.20 - $216 at $180/hr) 3. Reverse clean and flush cooling system. (1.50 - $270 at $180/hr) Are the aforementioned services necessary when replacing the radiator? Does the radiator replacement quote I received on your site include these services? Thank you.
