How to tackle this job:
1- Remove the left side "slidable vent cover". First twist the dzus fastener hidden on the lower portion of the fairing, then pull and remove fastener (don't lose it) push cover forward and remove, this gives you access to the coolant reservoir for checking and topping off.
2- Pull the reservoir cap and the tube attached to it completely out (tube is some 2 inches long, going into the reservoir).
3- With a 50 cc syringe and tubing (amazon) remove all the old coolant. Be thorough, its easy.
4- Now fill the reservoir to slightly above (1/2 in.) "full" mark with new coolant, use the syringe and tubing or a funnel with long, thin, flexible tube available at any auto store, then replace cap with its tube back in securely.
5- Remove the front bezel panel.
First remove the headlight adjuster knobs, then the 4 big allen screws and the few quick connects, make sure to remove all quick fasteners, there are some hidden on the low portion of the bezel.
6- "pop" the bezel from the fairing by gently pulling/separating the two parts. I used my hands only, some people use a tape-covered screwdriver to separate bezel from fairing, not really necessary if you are careful and patient, it does take some effort but they "pop" out, just by prying apart, start about halfway from mid line on each side. To remove it you will need to open and then close the glove box compartment to make it easier on the left side.
7- Once top bezel is removed, open glove box and remove the large phillips head screw easily seen with door open.
8- There is a screw holding the corner of the glove box perimeter to the fairing out in the front portion of the perimeter, remove it.
9- Remove the large Allen bolt holding the fairing on the side.
10- This gives enough free play of the plastic parts to remove the perimeter of the glove box (black piece) and once this piece is out, there is enough wiggle room/space to get under it to the radiator cap.
11- Remove radiator cap.
12- Go steal some nail polish from your wife, put a tiny mark on the drain bolt and the block, that way you will know exactly how far to tighten the bolt after draining the coolant. RETURN SAID POLISH TO ITS PREVIOUS LOCATION!
12- There is a copper washer on the drain bolt, manual says to replace but it is perfectly reusable, remove drain bolt and out goes the coolant!
13- Once it completely stops draining and dripping, give a generous swig of coolant to the radiator, you will see another stream of coolant pour out, with this maneuver you do not need to remove the lower radiator hose, all the old fluid sitting in that tube has been rinsed away with new coolant.
14- Replace drain bolt with the copper washer, tighten to the mark you placed previously, do not over tighten!
15- Fill radiator SLOWLY
, a few ounces at a time, stop and seat on motorcycle, swinging bike side to side, you will hear fluid gurgling inside, squeeze hoses gently if you want, again to burp as much air as possible, continue this way until you see coolant at filler neck.
16- Replace radiator cap, ensuring its fully
screwed back in.
17- Start engine, let it warm up, give it a few revs once warm, get it to 220 F or until radiator fans kick in (now it's a good time to check if both fans are working properly and ensure hoses are not leaking) leave engine running at idle until fans stop, then maybe another minute, shut engine off.
18- Start buttoning her back up while it cools and draws coolant from the reservoir. If you overfilled the reservoir it will probably end up in the middle of the range and no further topping up will be necessary, this however may take several hours, so be patient.
19- After several hours, if reservoir is under the low mark, top up with coolant, otherwise you are done!
20- Put the side vent with dzus fastener back, clean up any spills and wipe fairing clean.
Dispose of used coolant at parts store.
As Russ says; "This is how I
do it, you may have other options and that's perfectly fine" with 2 years of use and 10,000 miles fluid was crystal clear, no need to mess with flushing or adding distilled water, removing hoses etc. Again this is my opinion.
Judging by the amount used, I feel with this method 85-90% of the coolant was replaced.
