Coolant & SCA Additives!!

After doing a good flush, very little contamination will occurr in the new coolant, and the HD ELC will continue to be very effective at inhibiting cavitation and corrosion. I would not recommend any type of chemical flush to "clean" the engine block any better.

Thank you Gooch. Since i'll be converting to the HD ELC, I'll go ahead and pass on the coolant filter in order to save some $$$. Sounds like the coolant filter isn't necessary with HD ELC.

Just for completeness, and so maybe someone can compare the Ford
info with what has been posted so far, here is what the Diesel Supplement
to the Owner's Manual says:

Coolant specification:
Use only a permanent-type coolant that meets Ford Specification
ESE-M97B44–A such as Ford Premium Cooling System Fluid
E2FZ-19549–AA. Do not use alcohol or methanol antifreeze or mix them
with the specified coolant.
Use of the wrong coolant may cause radiator and/or engine damage.
Plain water may be used in an emergency, but replace it with the
specified coolant as soon as possible to avoid damage to the system. With
only water in the system, do not let the engine run hot or remain parked
in temperatures below 0°C (32°F).
Coolant conditioner (liquid)
A supplemental coolant additive FW-15 has been added to the coolant in
this engine.
This additive aids in the prevention of rust and scale buildup on the
internal parts of the cooling system. Prevention of rust and scale buildup

allows for proper dissipation of heat generated by combustion.

A coolant mixture of 50% coolant concentrate and 50% water is
recommended to maintain best overall performance. A 60/40 antifreeze
to water ratio is acceptable for extremely cold climates, but must be
returned to a 50/50 ratio at the end of the winter season.
Vehicles with diesel engines typically are used to carry heavy loads and
accumulate mileage rapidly. These two factors cause the additives in the
coolant to “wear out” in a shorter time. Ford recommends an interim
service interval performed at 12 months or 24 000 km (15 000 miles),
whichever occurs first.
Add 237–295 ml (8–10 oz.) of supplemental coolant additive FW-15
to the cooling system. For vehicles with extensive idling time, add
237–295 ml (8–10 oz.) of coolant additive FW-15 after every 500 hours
of operation.
Operating engine with insufficient coolant and/or coolant additive can

cause severe engine damage.

Okay, I printed out this message thread, read it carefully,
highlighted which coolants Gooch recommended, and after
culling data, here is what I came up with...

"There are Heavy Duty Extended Life Coolants (ELC)
specifically designed for diesels. "

From this message thread:
CAT ELC
Chevron Delo ELC
International's Fleetrite ELC
Mobil 1 ELC
Prestone Heavy Duty ELC
Shell Rotella ELC

Almost all heavy duty diesel manufacturers use Heavy Duty ELC's
meeting the most strict requirements in the industry...Caterpillar's EC-1.

For reference, here are some TLA's used in this message thread:
ELC - Extended Life Coolant
G-05 - Ford's Gold (universal) coolant
HD - Heavy Duty
IDI - Intenational Diesel?
PSD - International T444E Powerstroke (Ford Powerstroke)
RMI - RMI-25
SCA - Supplemental Coolant Additive

BTW, how does this apply to other Diesels like Chevrolet 6.2, 6.5 & Duramax
and Dodge Cummins engines?

so if I have read everything here correctly, if one does a full flush, pulls the block plugs to drain the block down, and fills up with a good ELC diesel coolant, there really isn't much of a need for a coolant filter?

Walmart by me has Peak Final Charge Global on clearance right now for $4.50 a gallon. Which from reading up on it is an ELC coolant that meets the Cat EC-1 specs

Can I use the green Walmart 5yr/150mile extended life (ELC) antifreeze (label that shows ASTM D-3306 ASTM-D4985 spec) with SCA (Wix (aka NAPA brand) ?

-Thanks

No coolant filter needed?? I have to disagree.
The filter still catches sand casting particles that break away from the engine.

Yes, you can use it. Be sure to use the test strips on a regular basis and add the SCA as needed.

I have been advised by someone else not use the Walamart EL 5/100 antifreeze ( HOAT ) in my Ford IDI . This person told me it may accelerate the deterioration of of the oil cooler seals and it is not compatible with the nitrite type SCA ( NAPA Kool, Penray etc ) . Those cooments sounded reasonable . I decide to play it safe and purchasedthe Peak green (non-EL old type inorganic antifreeze at Advance Auto Parts and will use it with the NAPA SCA .
