98 S70 N/A: Question about coolant and expansion tanks

[theWIFES_S70]

Marco..drop coolant off up here, we can discharge into drains up here. No for that in NYC, of course.

Just don't do that on my side of the river on a rainy day - as it will end up in the river after the plant has to go into bypass after exceeding capacity. =p

Makes for an interesting swim in the Hudson as well...

I'm actually pretty careful about chemicals! And now that NYC takes it four times a year, I take advantage of that stuff! But yes, I think I'll drop off some bottles next time I drive up to Albany. I figure I can just leave them on his driveway, no?

Hey everyone, just wanted to update this:

2K miles later. No sludgy sediment at the bottom of my expansion tank. So yes, sludge can get stuck into the crevices of the expansion tank.

Hope everyone is doing well!
