Coolant Additive
I changed my anti-freeze this weekend in my 2001 F350 Crewcab Diesel Pickup. How much of this additive should i add. I ran water through the system to flush the old anti-freeze out and added new. So in other words i currently have none in my system. I have been told 2 bottles by one dealership and 4 bottles by another. The maintenace manual says if the system needs recharging add 4 oz. per gallon. There are 16 oz in a bottle. Since there is 8 gallons of coolant (4 water/4 anti-freeze) i am assuming that i need to add 2 of these bottles. i am also assuming that since the coolant system has no additive currently in it that it need to be re-charged. Any feedback is appreciated.

OK, What additive? I've heard of it before but can't find what it's all about. ie: what, why, where, when. What happens if not. 2000 7.3L 4x4 CC; My owners manual says nothing about it.

Can someone tell me where I can order the test strips online? I went to about 5 different parts stores locally and the Ford dealer. No one had them, or even knew what I was talking about.

I believe NAPA may sell them as well.

CAT, Cummins, Detroit Diesel and truck lube shops should also have the strips. NAPA has the additive, if they can't find it in the catalogs, they should be able to cross-reference it from Fleetgard P/N DCA4.

I got test strips at NAPA, but you can get them online from Fleetgard.

Buffalo,
As others have mentioned any of the Internationals or NAPAs have the kits. I bought mine from Carquest. The kits are expensive and have expiration dates so buy no more than you need. Also try to get a sample of the coolant in the block vice the expansion tank. The water in the tank is stagnant and will not give representative results.
Rocker: The D in DCA stands for Dry not Diesel. The acronymn is Dry Chemical Additive. In this case the "dry" chemical is added to a liquid to make addition easier.
What is being tested for along with pH and glycol is the change in nitrite level. Not the concentration of the additive. And more is not better. Too much is as bad as too little as chemical corrosion of the engine will occur.
Be careful and go slowly. You can always add more but taking it out . . . .
Or you can just use the gold antifreeze and avoid all of this.
