[scott_son]

i know this is basic. but please i wana make sure i am doing the right thing for this temp...

Its currently 32 degrees, i left my water wetter in WAY to long...i need it out ASAP...

please someone explain to me in deatail how i am supostue change/flush the coolent on my RC 51.


this is how ive done it over the summer....take both radators off, flush them with garden hose....let coolent drain from engine...then flush the engine block with the hose. then refill threw the cap on the ratiator? do i fill the resovior too?

[robfromsc]

WOW, thats the long way around, no need to take the rads off.. search thers a thread. but in short, pull the hose from the pump and the right rad, refill with clean water, start, pull them again, repeat till its all clear, drain the bottle, fill it, smile

[scott_son]

thanks buddy.. yah i relized after reeding the service manual that ive been doing shit the rediculiously long way...

I drained the coolent like you said, but i didnt fill with water to clear the system i just filled it up....

[robfromsc]

Yeah, its kinda messy and you need to be sure the t-stat is open so be careful not to burn your tootsies! But with the fill and flush you get the block and the left rad clear. I would not use a hose, you don't want tap water left in the system. I always just flush it with distilled, pickup two of the big containers...2.5 gal? From the store and your golden. Stuffs cheap too! Good luck, just make sure you check it the next day or something to be sure there isn't a bubble.

yup, always use distilled water!! 2gallons should be waaaay more than enough to flush it and fill it (w/ waterwetter or engine ice or whatever your gonna use). but dont use tap water.

also, let the bike heat up to 180 and then flush it again (after it cools a bit)... you'll get almost 100% of the old stuff out.

dont forget to bleed it.

Just a tip to avoid you troubles: drain the system, take the thermostat out and then flush the system as many times as you want. Then you'll have all winter to put the thermostat back in.
Extra smart*** tip: why does everybody insist on using these miracle coolants and nobody uses the genuine Honda stuff? It works, it's expensive but still cheaper than many aftermarket products, it won't leave nasty deposits and it will really help keeping corrosion at bay. If you want a cooler bike run some radiator scoops.

Most race clubs and many trackday events require watter wetter engine ice or equivelant

a tip from the service manual as i just did this before my track day a few weeks ago, with the radiator cap off, blip the throttle to get the air bubbles out. it took me 3 times to get her all clean.

Not living in the US I assumed that you had the same track rules as around here: just distilled water as coolant, though many lazy gits (including one typing right now) can't be arsed and will just stick to whatever they are using at the moment, hoping in their good star.

If there is ethelene glycol that gets from your engine to the racing surface you will put other riders at risk

Several orgs I've ridden with also state that you will be the one out scrubbing the track, if you crash and have glycol coolant still in the bike.

Now, I've never seen anyone out on the track scrubbing. But I have a feeling that the peer-pressure works pretty well....

Besides, it takes all of a half an hour or so to flush & change the coolant. It's not rocket science.

Never ridden an event that required anti-freeze removal. I don't race, only do track days and schools.
