I have a '96 4.0 with 70k miles and the coolant isnt looking to good. So I'm going to give it a good radiator flush.
I picked up a case of Prestone's 50/50 mix antifreeze and distrilled water. I also bought a bottle of Prestone Radiator Flush. The napa counterman warned me against using this product unless the coolant is really bad. Mine isn't horrible, just needs changing.
He said it's such a strong flush that it would put additional wear and tear on my cooling system. He recommended I just run water in it and use no cleaner.
I will be using a 100% fluid exchange machine. I plan to fill the machine up with water, and possibly the cleaner, and let her run for 15 or 20 minutes. Then fill the machine back up with 6 gallons of antifreeze and let that flush through.
Should I use the prestone flush or not?
I also plan to replace the upper and lower radiator hoses, radiator cap, thermostat, and the thermostat housing. All parts will be from the dealer. Should I replace these parts before the flush, or afterwards and just top off with additional coolant? How much will drain out with both hoses removed?
Thanks for the help
