I posted this issuein my new SD thread, but figured I'd get better/more responses if I make one for the issue... The water pump on it failed while I was coming home, and after taking it off, its obvious why. The inside is completely rusted, and its making grinding sounds when it turns. It seems like the inside of the engine is also very rusty... How do I de-rust inside it!? This is why you do not use the green coolant!
