CALLING ALL COOLANT EXPERTS!!!

So, like the title says, I want to know exactly which coolant test kits I need to perform ALL the coolant tests for both cooling systems for my 6.7L. I have spent time researching posts and have come up with several opinions on how to do the test but I would really like somebody to step up and walk me through this, including, the correct test kits I need to buy . Like most of you, I don't feel comfortable with the stealerships telling me they tested and everything looks fine! I want to learn how to do this myself correctly and know for sure it is being done right! Thanks in advance for all the help.

My dealer told me that while I could test it myself and if it indicated the need for additive, I would be SOL as Ford does not allow it to be sold to te public.

I trust that dealer very much. They tested it for free every time it came on(13k miles or so) and added some around 45k.

Three products are available for ensuring the life and
health of the coolant: one tool, a test kit and a coolant inhibitor additive:
• Rotunda tool ROB75240 available from your dealer – recommended
refractometer to test coolant concentration.
• Rotunda 328-00008 (Antifreeze Coolant ELC Contamination Kit) –
Evaluates the corrosion inhibitor additive strength. Note the first step
is to verify the vehicle’s coolant concentration is in the correct range
of 40 – 60%. Coolant concentrations outside this range will not
provide valid test results. If the report results in a pass (i.e., the
cooling system does not show excessive contamination/the corrosion
inhibitor additive strength is sufficient), no action is required. If the
report results as insufficient (does not pass), the corrosion inhibitor
additive strength of the coolant is too low. If the ENGINE COOLING
SYSTEM corrosion inhibitor additive strength is low, add 48 fluid oz. of
Motorcraft Specialty Orange Engine Coolant Revitalizer. If the
SECONDARY COOLING SYSTEM corrosion inhibitor additive strength
is low, add 16 fluid oz. of Motorcraft Specialty Orange Engine Coolant
Revitalizer. The coolant can be recharged with this additive up to two
times before the coolant must be changed-out. When exchanging the
full coolant volume, the system must be flushed and refilled per the
instructions in the Workshop Manual.
• Motorcraft Specialty Orange Engine Coolant Revitalizer – Additive to
boost the corrosion inhibitor level based upon the test results of the
Antifreeze Coolant ELC Contamination Kit. The revitalizer may be
added two times over the life of the coolant. If additional dosages are
required, the cooling system must be flushed and refilled per the
instructions in the Workshop Manual.

I don't think it is plagiarism to copy and paste from the owner's manual

Why not go with ELC coolant and not have to worry about testing and adding sca's? I run caterpillars ELC. It's 300,000 mile rated and needs a caterpillar additive at 300k interval and changed after another 200-300k miles

Does the Cat ELC have the Carboxylates that coat the internal metal of the CGI block?

The main corrosion inhibitor is the Carboxylates. They slowly coat the internal metal and prevent corrosion.

On Edit, CAT ELC does contain their version of Carboxylates
CAT still recommends that you add the CAT extender at certain mileage to improve the Carboxylates and that you test for the Carboxylates periodically.


CAT says no need to add SCA since they are used with Nitrite based coolants. Which CAT's ELC and Ford Speciality Orange are not.

So what is the Advantage of using the CAT ELC vs the Ford.
Both products require periodic testing
Both products require the adding of Carboxylate boosting additive at certain mileage.
Neither product requires any SCA's, in fact the use of SCA's will require a flush and refill on the Ford system.

CAT does show 600,000 mile life vs Fords 105,000 life for the coolant. How much of that extended life if because of Larger capacity cooling systems, hiway mileage vs stop go mileage typical of pickup and other wear factors? I personally think I'd trust my Ford designed engine to use Ford Coolant.


I'm not sure I see the reason to swap out the Ford Coolant that this engine was designed around in favor of using a CAT coolant that was designed for a CAT engine.

Painted horse- frankly I'm no coolant expert, I'd have to research that and get back with you.
