Glitter in coolant?

Postby bob850 » Fri Apr 21, 2017 12:56 pm

In my 1999 V70 that I just bought, which has a 2004 or 2005 S60 T5 engine in it, I replaced the radiator and heater core, since they were both leaking.

When I drained the coolant, there was a bunch of silvery specks in it, looks like glitter. I think it is aluminum since it did not attract to a magnet.

I'm guessing either the previous owner used "stop leak" at some point (which has similar looking particles), or the water pump is going bad in some way. I flushed the coolant and am going to see if it comes back in the coming days.

I was told the engine has about 80K miles on it, and the water pump is original as far as I know.

Any other ideas on what the glitter could be from?

There is a lot of Al in these engines Bob.

I wouldn't worry about it too much - maybe drain a liter of coolant in a few months and see if it is still there? Ill bet it is gone.

The pumps on these cars are robust and last 200k miles. If the coolant isn't really crappy and dirty it has been maintained, and I would run the original pump until the timing belt is due or more.

Ok, thanks. I will continue to monitor it. We have two 850s and I have never seen this glitter in the coolant of their engines.

Mm. hopefully not metal particles. The original pump is solid, but a replacement non Volvo/Aisin/Hepu one is a ticking bomb. I can only see metal shavings coming from a water pump in the coolant, the only rotating metal thing that touches this fluid. Unless the coolant mixed with some transmission fluid inside a broken radiator.

The water pump is a Volvo pump (says Volvo on it). I'm guessing its the original pump. They previous owner who replaced the engine said he pulled it from a 2005 S60 T5 with about 70K on it.

Rethinking. You can get a quick answer by flushing it for 15 minutes, the filling it with just water, running it around town for 30 minutes, then checking the water for glitter.
