HI
SCA's is Supplimental Coolant Additives.Fleetguard and Napa Cool are the two that I have used.Take the truck to a big truck dealer and have them test it.You can buy the test strips from Fleetguard but you get 50 of them and they are only good for 1 year.You'll use 2 of them and then throw the rest away.Most truck mechanics will test it for free or less than $10.00.
They can't test G05 coolant, thats the new gold colored anti-freeze.Test strip don't read right.But there is talk of coming up with a new strip for this type of coolant.Ford doesn't recommend using SCA's in the G05. It took them 5 years to recommend it for the old 7.3L with the green anti-freeze so I've been adding it anyway.After they started haveing to replace pistons and heads while under warrentee.Ford.com has a FAQ on their site that shows pictures of the damage that was caused.
I changed the waterpump a couple of weeks ago.Found some light alkaline deposits but that could be because I forgot to add SCA's for about 50,000 miles.I usually have to add 8oz every 20,000 miles.Hope this helps.
