I recently drained my coolant and replaced my water pump. I'm filling the system (2013 model) back up with coolant and as it works its way through the system it gets speckled. I haven't dealt with this before so I wondering if this is normal. I'm not sure if I'm being paranoid and it's just bubbles from it getting so hot, or it's something else. It got progressively worse as it went on.

Another question: the manual does not say how high to fill the coolant. As I'm pouring it in the access neck, how high should the level be?

This stuff wasn't present in my old coolant that I drained. It was pretty clean.

I think that you are right in that it is just turbulence in the coolant, not something like metal shavings or something else. Besides, if a gasket is letting coolant into the oil, you will see and smell it in the engine exhaust.

Like a car, you basically just fill it up to the top. I tend to leave a couple cm from the neck top. Remember that warmer coolant expands so it will look fuller than it is, until it has had time to cool.

I drained it and am flushing it. There are a lot of metal shavings in my coolant.

So I'm on my third flush. Coolant is gone basically and I still have a lot of metal coming out. When I fill up the radiator cap, sh*t keeps showing up on the top, like what's pictured above.

Maybe the previous water pump ate it's bearing and it's just the leftovers from that piece?

I don't know what to recommend, other than continuing to flush with distilled water until debris stops showing up in the water. Also, recommend charging your battery, many starts in a short period of time likes to eat up your battery

I don't have a charger but thanks for the heads up. If it doesn't start I'll know why haha.

Drained the oil to see if it had any metal shavings and it did not. However it was extremely frothy and has a green hue to it (I have oem green coolant / however the oil is Mobile 1 Racing 4T and only has a few rides on it). I did a little test of mixing my oil and coolant in a pan to see what it looks like and it turned into a thick brown substance with the consistency of honey, so I don't think I have much, if any, coolant in my oil. I would like to get an oil test performed on it though to be sure. Anyone have any suggestions on who to use?

Took the radiator off and found a bunch of chipping paint on the inside of the low exit port. I believe that's causing the "floaters" on the top of whatever fluid goes in the system. I'm going to finish flushing the radiator by itself in the morning, along with each side that'll let water pour trough it. Then I'll put it all back together and flush it some more until the metal flakes stop coming out.

Try flushing with distilled water and vinegar. The vinegar will help to carry all the particulates faster.

Just add a tiny bit (couple of ounces of vinegar) to the distilled water. Then I would flush with JUST distilled water 2-3 times to get it all out.

I did this with an 08 R6 I had after it had set for 3 years...pulled all sorts of junk out of the system...

To answer the level.. Keep filling it until it's full on the neck, the burp it a couple of times to get rid of the air bubble (rev is sharply and release)

and also keep filling it until it's about 75 degrees celcius when the thermostat open as well.

You'll notice that when it hits the thermostat open, the level suddenly dropped :)

So I flushed the system about 15 times. I was still getting a "metal flake" in the water. I did some more digging and found that it could be a product called Alumiseal that is put in the radiator at the factory. I was still having slivers and a couple larger metal pieces come out up until the 13th time. I took off the new water pump and took it apart to make sure there were no metal slivers on any o-rings or anything like that. I've got coolant in it now and will take it out for ride when I get the fairings back together. (I'm going back to orange)

If anyone wants a 600rr, I've got one I'm looking to sell hahah.

Just and update to this thread:

I'm buying a new radiator to install soon, and will probably do another flush.

When I did my oil change, the oil came out frothy and had another darker, heavier liquid in it that could be stirred up with your hand, most likely old oil from the previous oil change (this oil was only ~100 miles old). I'm sending a sample to Blackstone to see what's going on. My guess is that a small amount of coolant entered via the water pump / crankcase o-ring as it was covered in coolant residue. It was replaced alongside the entire water pump. The bike runs perfectly, no smoke on startup, no oil in the coolant, no visible leaks or seeps, so I've pretty much ruled out head gasket. Still have zero idea where the metal shards & chunks came from.

the junk came from a cratering water pump.

a bit of schmoo in the water won't hurt anything. the cooling passages in your engine are large, there aren't any small orifices that have to handle water. the pump is solids tolerant by design, no worries there.



the stuff in your oil is probably water. remember water sinks in oil.



just flush the crap out of it and be done with it. no need to buy a new radiator. the new one will have nothing that your current one doesn't.

The old one had large chunks of paint flaking off the inside of the mounting hose. I got what I could off, but I was still getting crap in the coolant even after a **** ton of flushing.

Did you try the vinegar route? It will eat all that **** up and wash it out in the flush...vinegar is an acid and will work to break it all down with a couple of flushes.
