if your truck has the gold antifreeze to begin with you dont need the SCA if you change the coolant every two years. you only need the SCA if you have the regular green antifreeze. you can get the test strips at international dealer,

That being said, some people have switched their 7.3's that came with green to gold, myself included (I use Zerex G-05 brand from Autozone). It is extremely important that you throughly flush your system of all green coolant before changing to gold (I flushed my system 5 times with tap water and 3 times with de-ionized water), and I also added a coolant filter. If you are interested in making the switch, search this 7.3 forum, there are several threads about it.
