Unbelievable... Brand new colling system!

After 2 weeks of normal driving, I find THIS in my radiator... I changed my entire cooling system 2 weeks ago. EVERYTHING except the heater core. I did flush it with water and vinegar though. Compression tested good and oil is still fresh and clean. Your thoughts?

Probably should flush out the block.

When you had the water pump out, do you remember how clean it looked inside?

Of course I also forgot to mention, I always drain from the radiator AND the block plug.

I was gonna take a picture of the old pump, but I guess I tossed it. The fan was VERY deteriorated. The "bent-in" parts of the fins were gone completely. Leaving a razor-thin fan.

The coolant was turning this color before I swapped everything out. That's what made me replace everything in the first place.

How well did you flush the heater core? Looks like stuff that might have been loosened by the vinegar, and is finally disolving into your system. Could also be that the improved waterflow caused by the new parts, is causing errosion of the built-up sludge in your block? How well did you flush your block, did you just drain and refill with water/coolant, or did you dump, refill with water and run till hot (with heater on full), redump and run water through block until clear? My bet; that is sludge from the block.

This was the fresh coolant I just put in after five minutes. Flushed engine and radiator with hose. But did NOT let the water heat up. Just flowed it through, drained and filled with coolant.

Again, EVERYTHING is new. Besides the heater core. Everything was flushed extensively. No stop leak has been introduced.

You probably had a bunch of this stuff in the engine block. You may want to remove the thermostate, pull your radiator hoses off and use a garden hose to push a lot of water through the block. There are cleaning products made for that too, if it becomes necessary.

How many miles? The only thing I can come up with is the new fluid/flushing broke up some debris in the heater core/engine block. I agree that it looks like Stop Leak, but you said you flushed everything and didn't use that? I've also heard that you should flush new radiators before installation, but that's quite the amount of "sludge" there.

185,000... Does that prestone cleaner work? Not the FLUSH but the one you mix with water and drive for 3-6 Hours?

All that stuff collected in your block because the pump had no impeller. Now she's flowing and all that crap is moving around. Flush it good with thermostat out.

Some may have come from the heater core too, if it's stop leak.
I agree with the others, pull the thermostat and get that water hose in there for a while. You wont get all of it, but I bet it gets a lot of it.

If you haven't already installed one, I recommend a flush and fill kit available at any parts store for around 5 bucks. It's basically a t-fitting that gets spliced into the highest point of a heater hose. I put one on every vehicle I own, and it allows you to hook up a garden hose and really flush out the system. As a bonus it makes refilling the system a lot easier because you can purge the air just by leaving the cap off while you fill it.
