Fluid flush

[Scootergptx]

Had my sister in laws car over at the house this weekend and did the brake flush I told her I would do last month. Figured it was a good time to do the bike too. Flushed both brakes and the clutch.

Didn't bother me that the fluid was dirty, I expected that. I was surprised that the inside of the clutch reservoir was coated in a black film. First thought was the lid wasn't sealed. Hasn't been leaking any since I bought the bike, but I have no idea about before then. Cleaned it out and filled it back up.

Had changed the oil last weekend, so I guess next weekend would be a good time to flush the coolant system. Haven't looked at the service manual yet, but I remember on my old 750 vulcan it said to put sealer in with the anti freeze. The reasoning on that was it had lubricants as well. Is it the same on the bigger bikes too?

no need for addatives but as u know everyone has an opionion
no rad. drain on mine [010] nomad -- I took rad off to back flush good because the coolant had LOTS of paint flakes in it -- with filler cap off and thermostat out u can use water hose to flush both directions both engine and rad. -- some paint flakes as big as corn flakes -- took a while to get it clean--I use green long life coolant 30-40% -- it cools better than 50% and protects to below zero [read the chart on bottle] and will not damage the engine -- in the past I used water wetter but could not see any improvement at all in 2 different bikes -- fyi im a retired master auto tech with over 50 yrs experience on us and Asian products and don't believe in wasting money on snake oil treatments

I have tried quite a few but none performed as advertised for me

Had same issue with black stuff in the master cylinder.

Plan on flushing the cooling system out 4-5 times to get most of the black flakes out. Little dis-concerning when you see so much crap come out with the
coolant, but just keep flushing. To me it seemed that the lower coolant pipe(where I disconnected hose to drain fluid) looked like the source of the flakes, so I used a bottle brush to clean it and flush it out. Lots of flakes on 1st flush.

Really no need for adding the additive.

Hope this isnt an issue because its on a different forum, but this is a good step by step description of flushing the coolant on the Voyager.

On my Vaquero, I just did the brakes and clutch last month (Feb.) complete flush and yes, there was a little teeny bit of black silt in the bottom of the clutch reservoir all clean now. I also just did a complete coolant flush. You have to pull the tank, and you pull off the lower cowling in the front around the radiator completely away. This will expose the cross brace at the base of the radiator. You take off the bolts, one 10mm holding a wire harness, and a pair of 12mm bolts holding the brace on and once this is unbolted, you pull it down to the side out of the way so the bottom of the radiator can come forward a bit. You can now put your drain pan underneath the radiator and then loosen the hose clamp at the bottom. Pull the hose off to drain. Then put it back in place and fill your radiator to the top up at the backbone completely with diluted water, then pull the hose and drain again. I did this twice to make sure everything ran out clear. Place the hose back on, tighten the clamp, and fill with your coolant of choice which in my case, I put in non-glycerol "ice water" racing coolant. The system takes just over a half gallon. In the interim of all this you also have to remove your spare coolant tank that sits inside the left side cover, clean and flush, blow out the hose that runs to it from the fill port, replace it and fill to the top line with the new coolant. After filling the coolant, squeeze the top hose to make sure no air bubbles remain in the system. Make sure the fill port is full right to the top then replace the cap on tight all the way. Replace the lower shroud and fuel tank and you are done. Start and run the bike all the way to full temp range, then shut off and check the spare coolant tank and if necessary, fill back to the top line.

Hey , I remember you from the 750 forum, looks like you have picked up a pretty sweet bike too!

That is two I remember from the other forum now, you and Chuck A. Good to hear from you again, Denny

Good to see/hear from you again as well.

Nice looking Voyager you have. :tup:

Think I still have parts for that old 750.
