flushing radiator

Want to replace my coolant. can anyone tell me how can I drain the coolant in my radiator properly?

I always take my car to a shop to do this, just because I don’t want to have to deal with the disposal of the used coolant. They don’t charge very much.

You gotta drain the radiator (rad. drain plug), and if you want to do it complete, drain the coolant in the block too (17mm bolt ont the front of the engine block, behind and to the left of the header) … need a torque wrench for that one tho.
Also, remember to loosen the bleed bolt when you refill the coolant, and fill the rad until it is flowing water constantly (no air bubbles).
