I have a 99 Taurus, the plain vanila 12 valve engine. It is time for me to do something with the radiator before the radiator does something to my wallet. Last winter I pulled the hoses from the heater at least 3 times to flush the thing in order to get heat. Inside the radiator reservoir there was the common sign of brown poop that others have called "death."
Well, I want to prevent the next cancer stage from occurring by flushing this thing out. My thought is that whatever is added for a flushing detergent it should be left in the cooling system for a couple of days or so to get this crap out. Next, I don't recall seeing a radiator drain cock on the radiator but maybe it is hidden out of sight.
Questions-- what is the recommended way to drain the radiator? Next what is recommended for flushing the radiator along with how long should the flushing substance be left to circulate before draining? Finally, is one flushing deemed adequate or should the flushing be repeated?
