Reply to "Radiator fluid change"

Finished the dirty deed yesterday just going with the Prestone extended life coolant. Actually it wasn't too bad. Since my Fluidine doesn't have a lower petcock, I just inserted a plastic wedge between the hose and pipe connection under the car until the fluid came out (that way I didn't have to monkey getting that old hose off as the hose was still good). Before I did all this though, I drained and cleaned the overflow tank as it had rusty color water in it. This was quite different color than what came out of the main fluid pipe under the car. Maybe because the coolant overflow tank can rust some on the inside? I would think that water would be recirculating in the system from the overflow, but apparently not due to the different water color I saw. Anyway, for those who just drain and then refil without flushing the entire system, maybe consider trying to dran and clean the overflow tank before refilling the system.
