So this morning I flushed the radiator on the wife's car ... last time I did it the twin towers were still standing (actually I think Clinton was still in the Whitehouse) ... oops.

Had to drain it, fill it with the clean & flush + water ... ran it for over an hour ... drained it filled it with water ... ran it for a bit ... drained it and filled it with water again ... drained it and filled it with water AGAIN and drained (pouring water into the radiator until I got clean water coming out). Had to pull the overflow reservoir off and clean it in the kitchen sink. Its amazing how dirty a coolant system can get with two decades of neglect.

I never think of the wife's car since she puts so few miles on her car (I do oil changes once a year even though she doesn't put 3k/yr on it). Thankfully its a 1990 Nissan 240sx (probably the best car Nissan ever made) and the coolant system is way over built for the car. Hell it took 45 minutes of sitting there idling in the driveway to get the heat gauge to move off of C.
