medicrxdoc It sounds like the reciept has Zerex G-05 which is the same as the Ford gold coolant.

Here is a link to the Zerex website Valvoline.com > Products > Zerex > Antifreeze Zerex > Zerex G-05 Antifreeze / Coolant.

Are you sure the coolant is green? If so, it wasn't the G-05 or it wasn't flushed properly. Since you found green in the brake fluid, its possible somebody topped off with conventional green and probably should be flushed and changed sooner rather than later.

joonbee Awesome info 2 Stoker. Thanks.

Sounds like I am in the testing category for now. Like I said it was just done, so I will get some SCA strips and test it. But when the money comes along I will get rid of this and go to the ELC or Evans. Will have some time to get some more reading and feedback in before I have to make that choice.

I am usually the guy who changes everything when I get a new truck, but if this coolant checks out on the SCA scale then I will run it. I have changed everything but the coolant. Paid off cause I found out that whomever worked on the truck last (FORD) topped off the brake fluid with green coolant. GENIUS. The next oil change I plan to go with amsoil and their bypass, then I will have a match set from nose to tail.

Thanks again for the help.

2 Stroker There are 4 choices for your Powerstroke....

Conventional coolant (usually green) with the addition of SCA at initial fill. Frequent SCA testing and maintenance there after.

Pre-charged coolant (usually purple or pink). Comes with an initial dose of SCA. Frequent SCA testing and maintenance required thereafter.

G-05 coolants. Comes pre-charged with SCA package. Fush required at 50K miles. Semi-annual SCA testing and maintenance recommended.

Heavy Duty Extended Life Coolants. Come pre-charged with carboxylate inhibitors. No testing or maintenance. Super protection. Super long life.

Specialty coolants. Evans. Waterless, pressureless. Long life. No maintenance or testing. Expensive.

Not to be used - Dexcool, Universal coolants, All-makes-all-models, etc.

I use Chevron's Delo HD ELC. Good for 750K miles/8 years or 1M miles with addition of an extender.

Get yourself some test strips so you know where you stand, i get them from the International dealer most get them from Napa and test the coolent before you add it may be good if you over dose you may take out the water pump should be checked about every 6 months. I use them on my 97 and with the Ford Gold but with the ELC coolent good for about 300k or 3 to 4 years then redose good for another 300k, it's your call.

joonbee IF it helps anyone figure this out. The coolant they used to refill is listed on the receipt as G-05 ccolant. Thought I read here somewhere that it was in fact a new green coolant they use adn you use this G-08 additive.

Not that money is no object, because it certainly is, just trying to make sure I only do this once and am trying to make this baby reliable for a LONG time. If this G-05 is ok then it is $5 for additive vs. the $$ to flusk and refill again. this work was doen about 5k miles ago.

thanks.

Just figured this was new and all the parts were new, so I could keep them clean. I have done the coolant bypass from dieselsite also.

This greens gotta go?

If so, it just had the VC-9 flusk when they replaced everything. Flush again or just drain out all the green and put in ELC?

This may be something new from Ford but i think they only have 2 the old green that the 7.3 take and the Ford Gold for the 6.0 & 6.4 If it were me i flush with distilled water a few times if everything is new EGR & oil cooler then do the Restore need to clean the heater and raditator cores then flush then add ELC coolent. Maybe someone will chime in on this one.

I bought a bottle from Ford and my question is, How much? It says on the bottle to use some test strips? and oz. per gal. blah blah. I have leared that the people here are typically much smarter than Ford in general. So I come to you for a recommendation. Should I find these strips or just put in the bottle?

Thanks alot, Jim

You had better do some here and get this right and dump the Green cxxp, and get some ELC coolent in it, read this and look at all the post about it.


ELC is the coolant recommended and used by International for this engine. .


Coolant Flush for changing to ELC

Drain coolant by removing lower radiator hose. Drain block from plug on drivers side of the block. Remove the thermostat. Replace plug in block and put lower hose back on. Put thermostat housing back on without thermostat. Fill with distilled water. run for 5 minutes then drain as above..Fill and run 5 more minutes drain. Put in 1 gallon of Restore an top with distilled water. Drive it for an 60-90 minutes then drain. Flush 2 times with distilled water or whatever it takes to come clear. Put 2 qts of VC-9 and fill with distilled water. Drive it for about 60-90 minutes. Drain and flush after. Flush 3 more times with distilled water untill it come out clean. Replace thermostat or put in a new one. Put hose back, make sure block plug is tight. Add 3.5 gallons of ELC concentrate and top off with distilled water. Make sure to run engine for 5 minutes between flushes to circulate the water good. Have heater on set to hi while doing this to flush the heater core too.
