Coolant test strip for VC-12 additive
Looking for correct test kit to test for corrosion inhibitor (VC-12). My truck's cooling systems have not been touched by anyone so I am not concerned with testing for contamination. After some light reading I bought R071-ELC, aka Ford Rotunda Part Number 328-071ELC (formerly 328-00008) hoping it's 2 test would do both. It appears the RA test if just part of the contamination test.
What test kit do I need for corrosion inhibitor?
Ford Rotunda 328-2050 (CTS-3) (was 328-00001)???
Assuming 328-2050 is correct, does VC-12 have both Nitrite and Molybdate? Or just Nitrate?
What is pass/fail criteria of the color chart, specific for Ford Orange coolant/VC-12
If <3 SCA units/gallon -> add 48/12oz VC-12
If >3 SCA units/gallon -> do nothing
???

Not trying to be a butt....but sometimes the answers can be found by searching the forums.
This topic was discussed recently about the additive and what is needed to test the coolant. You are using strips to test for nitrates only. Then testing the condition of the ELC.

Test procedure here.

Larry,
Thanks for the help. I have done a lot of searching however did not see the procedure on stroke.org.
In the Coolant Test Primary system.pdf it states to use 328-R071-ELC, and in the flow chart it specifically asks "Does the coolant pass the corrosion inhibitor level?"
The color card in my R071-ELC has only pass/fail identification for 'Contamination test'. Nowhere in the kit's (paper) instructions is the phrase 'corrosion inhibitor', hence my corn-fusion.
The R071-ELC instructions on the web are different that the paper copy in my kit, specifically for step 3 (or 'C'):
(Paper)Report results: PASS – your system does not show excessive contamination
(Web)Report results: PASS – your corrosion inhibitor does not show excessive contamination
http://www.acustrip.com/res/pdf/ELC_Card_011615.pdf
The test procedure states that Orange coolant uses carboxylates for the corrosion inhibitor.
Carboxylate is an organic acid.
https://en.wikipedia.org/wiki/Carboxylate
R071-ELC paper copy step 3 states 'The amount of organic acids remaining is a measure of contamination'.
So, one (well, me the over analyzing engineer type) would then ask is the contamination 'pass' result the presence or lack of organic acids? Would seem to be the lack, but appears to be the presence to according to Ford's procedure....

Justin,
If you follow the test procedures and your test strips do not show anything, I would keep on trucking till time to test again. From all indications of the owners who have tested their coolant, there have not been any that I have seen with low mileage that indicated any problems UNLESS they or dealer used the wrong coolant test kits. The coolant is suppose to be good for 105,000. I suspect some out there have run it many more miles than that as orange ELC has been around a number of years in the GM vehicles.

That's the plan. I though about just adding VC-12 at 35k and 70k...
But, my curse is that I have to know why? WHY? Aghhh!
Why do the highly trained dealership techs screw it up? Documentation?
