Question Cooling system maintenance-needed yet??

My 330 has about 26k on it, and is 2 years old.* I live in the panhandle of Florida, and it's very HOT.
*
I'm wondering if I should flush out my cooling system, just drain the radiator and refill, or do nothing.* I was thinking about going with 25% glycol/74% water/WATER WETTER.* I want the system to run cooler because I have heard that our cooling systems are not the absolute greatest, and we all know heat destroys engines.
*
If doing the whole system, any suggestions?* How-tos available?* I don't really have experience with this motor yet.
*
Thanks!

Your car is still fairly new, all you need to do is flush the cooling system and replace with 50/50 mix of BMW coolant and distilled water - do this every two years. BMWs run hot, no way around it. Water Wetter is nice but the 50/50 traditional mix is the best thing for you car. When you start getting past 60,000 miles then you can think about replacing parts (water pump, etc).

Abby normal? Classic.

From Young Frankenstein:

Dr. Frederick Frankenstein: [to Igor] Now that brain that you gave me. Was it Hans Delbruck's?
Igor: [pause, then] No.
Dr. Frederick Frankenstein: Ah! Very good. Would you mind telling me whose brain I DID put in?
Igor: Then you won't be angry?
Dr. Frederick Frankenstein: I will NOT be angry.
Igor: Abby Someone.
Dr. Frederick Frankenstein: [pause, then] Abby Someone. Abby who?
Igor: Abby Normal.
Dr. Frederick Frankenstein: [pause, then] Abby Normal?
Igor: I'm almost sure that was the name.
