Additive Headache
It has been a long time since I added sca to my coolant so I tested it and something is up. After adding three bottles of motocraft additive my test strips are coming up the same as it was before the additive. The middle pad is almost white and the last pad is black. What is up with this? No change in the strips after three bottles? I don't recall how much I had to add when I first got the truck but I don't think it was that much. And no change in the strips after three pints? Please help
Thanks
PS What is the coolant capacity? Cant seem to find that info.

Thats strange. I am still finding info that says 1 pint to 4 gallons. We have a little over 5 gallons so 1.5 pints sounds right. That means I have twice what we should have! What will happen If you use too much??

Hmm... I run coolant that has the SCA's already precharged so I have never messed with the test strips before.
I wonder if it has something to do with the actual SCA? Ford says to use FW-15?

Correct. Its 4oz to a gal on a full coolant change/charge.
Overcharged is hash on the pump seal. It will shorten
the pumps life with a seal leak.
Test strips do go bad. Also be shure its the correct test strips.
Molybdate, Nitrite and Freezepoint.
I have been told that DCA has a shelf life and can go bad.
But i have never seen a date code on any DCA.

Thanks, must be the strips. One pad is brown and I recall that means its bad. They are the right strips. What can I do to avoid this whole situation? I think Motorcraft premium gold won't need the additive. I am due for a flush.

I believe the gold contains SCA's.
So I just stumbled on this thread...??????????? Check it out
Anti freeze & driveline fluid ?? - Diesel Forum - The Diesel Stop.com
I believe I use the red colored fleet guard which is ELC if I remember right (it has the picture of the big rig on the front). According to these guys we shouldn't be using this of G-05?

Everytime I read these debates I wonder if my last decision on antifreeze was a good one. I wish someone would know for sure what to put into these trucks. By the way, where do you get the test stripes, my source ran out? Thanks
