I had the overflow tank off yesterday to do some work under it, and when I drained it the coolant that was in it was cloudy and full of debris..!! I should have poured it through a coffee filter to see what the debris was, but threw it out before I could think as that takes awhile ..... did have enough time to take a picture. Any ideas what might be going on here? I replaced the coolant last year about this time,, it was nasty looking then, but don't remember any junk in it.  |

Whatever it is, maybe it didn't come out with the last coolant change.
Did you flush with a hose? (Is that even the right method?)

That could be rust particles from the water pump impeller.

I've run it about four hundred miles in last last couple of days,, that will have gotten coolant back and forth from the engine into the overfill. I will take a look at what is in there, if anything, again in the next day or so,, this time if anything is there, I will filter it out and see.

Well. I put 8 or nine hundred miles on the bike last week and took the coolant reservoir off to clear the decks for a rebuild of the clutch slave cylinder. I drained the coolant and it is full of trash again.  This time I filtered it out and what I found was what looks like aluminum powder mixed with "glittery" particles...??  I did a search on the net and found several reports of "glitter" in the coolant,,, some have suggested that it may a stop leak product that had been added, but I found no instance of anyone defiantly pinpointing the source. Anyone run across this before?? The coolant that I am showing, is just out of the reservoir,, I have not drained the system yet. |

Can't imagine what would cause that.? If there was a failing water pump you would probably see an externap leak. The stop leak idea might be the answer. ???  |

I fill it with distilled water and run it around town for less than a day. |

I fill it with distilled water and run it around town for less than a day. Not too long ago, Motorcycle Consumer News suggested flushing with 50/50 distilled white vinegar and distilled water. After bringing it to operating temp, drain it and rinse with distilled water. Drain it again, and fill with coolant. The vinegar will remove the oxidized scale that forms in the passageways. |

I finally got around to draining the coolant from the motor and here is a picture from the bottom of the barrel.  No trash, so that is good. I have done some research and I think I know what was happening. It was just about a year ago that I was finishing up my bike, and put the coolant in. This being my first liquid cooled bike (Harley and Moto Guzzi's previously) I was not aware of the requirement for silicate and phosphors free anti freeze and probably poured in whatever was laying around. Well the action of hot expanding coolant moving from the system to the overflow tank where it would rapidly cool and de-pressurize, was causing the silicates to condense and participate from solution and that was what I was finding collecting in the tank. As the coolant had not been in there that long (one year) it had not started happening in the motor yet, so no damage done,, abrasive on water pump seals etc. So .. be aware .. the requirement for silicate and phosphors free coolant is real with a purpose behind it. I found Peak 150000 mile coolant to meet the requirements and be cheap, so that is what I used. |

Good to hear your bikes okay. Thanks for the write-up, and the heads-up too.

Jay Leno's Garage had a video on cooling system corrosion and how to prevent it with an expensive but permanent waterless coolant called Evans Coolant. Unfortunately NBC in their supreme wisdom couldn't leave it alone and acquired and redid Jay's website and now there's no search function so I can't link or put up the video for you. The video was interesting, particularly when Jay showed how much corrosion happens with aluminum in the cooling system. I'm sure the video still exists, just there's no quick way to find it. Nope, now I'm not sure it exists. Doesn't appear they set up any archive of older videos or articles - no wonder there's no search function. Just one more reason to say F%#& NBC. The link from http://www.evanscooling.com is broken too. Why the hell Jay would let his ex employer which he repeatedly proved he hated, would let them f with his website is a mystery to me. Well, delete that from my bookmarks. I have installed the coolant in my Valk and Wing and now cooling maintenance is no longer. At least until something breaks. |

evans cooling since '01, same color, same performance, never a problem. now if only the stuff in the fuel tank would last as long  |

Be sure you have a good ground ( YES , an electrical ground) to the engine and radiator. There is a term called silicate drop-out. It is not as common on the smaller engines , but it is caused by the dis-similar metals , aluminum ,brass,steel.
Who would ever think that a missing ground wire would effect the cooling system.

Is there already a ground from the radiator that we just check, or is this something we're adding? |

No , if the ground is there , just make sure it is clean. I have in the past seen several grounds left off for lack of knowledge. I have seen many radiators turn to dust thru electralasis. Some of the new anti-freezes are designed to prevent this. Do not take a chance.
