My wife was speaking with a mechanic when she took the car in for a safety and emissions inspection this past week and the mechanic told her that we HAD to take our Ford Taurus to a Ford dealership or to one of their shops (she was at a chain) to add or replace antifreeze in the car, otherwise it would apparently ruin our radiator.
As this is the newest car I've ever owned, I don't know if this is some peculiarity of newer vehicles or maybe something specific to Fords.
Can anyone provide some clarification?
