To be honest with you, on a newer vehicle like yours, I would suggest taking it to a reputable repair facility to where they actually hook up a piece of equipment to flush the system out. A 'do it yourself drain and fill' is better than not doing anything, but most national chain shops probably charge 50-65 dollars for a coolant flush which exhanges 99.9% of the fluid where a drain and fill only changes half. A well worth investment for such a minimal charge.

You should flush the entire engine and radiator. If you simply flush the radiator, you are not flushing out old rust particles and debris from the engine. You won't get the benefit of a full change if you only drain and refill the radiator. You pretty much answered your own question. There is a blend of radiator fluid and if you only put new in the radiator, what about the engine...how much is exactly in the engine...what percentage would you have to put back in to get the right blend? I have a tester with a bulb squeezer on the end and gauge on it that tells of the right blend for the temperature of your location. Do a full flush and the fluid will last longer, and the heater works more efficiently.

on that new of a vehicle i wouldn't think that it would be necessary to have this done,and no flushing the radiator doesn't flush the block out,unless they flush it as a closed system,and that should be done at a repair shop,and when you re-fill the system all the engine and the radiator will re-fill its self,if a shop does this they can drain everything and fill with the proper mix,good luck on it.

Once you drain your radiator it will drain your block too. There should be a plug on the bottom of your radiator. If your goingto do a flush go to any auto parts store and pick up a radiator flush and follow the instructions on it.

Your radiators plug is lower than your block it will empty out. When replacing your coolant and water mix ( i prefer to use distilled water) Make sure to turn on your heater so you wont get an air bubble in the line or it will take forever to get it thru and warm up..

unless you have alot of buildup (which you shouldnt) in your radiator, just empty and refill the radiator with 1/2 and 1/2. But bleed your system of course so you dont have any air pockets
