Re: IML: Cooling system "cleaning"

[sosmi@xxxxxxxxxxx]

Sorry to mis-direct my reply, I prefer not to use the more aggressive flush chemicals, some require a neutralizer flush, which simply adds to the procedure. It also can damage gaskets, heater cores, radiator, and water pump seals.I would rather do several Cascade flushes, on a really bad system.The t-shirt filter is a good idea, but an old sock in the return hose at the t-stat end, would give more filter area, and not plug up so quick. Everyone has a lost sock in their sock drawer, now I found another use for it. Dave.
