Bismic: My coolant temperature / oil temperature has been approximately 7 - 9 deg different running unloaded on level ground at 65mph. Do you think I should redo my flush with VC-9 to get as much coolant / rust residue out of the system as possible? Especially to remove any deposits from the oil cooler.

I had the same question to answer for myself. At 50k I flushed the system without the VC9. I decided I would not re-do it MAINLY because I have a coolant filter and the last 3 filter changes did not have much solids. Also when I drained the fluid the first time during the flush procedure, I did not see any solids.
Do you have a coolant filter? Did you see any solids during any of the drains?
Your temperature differential does not seem too bad to me. Have you ever seen it over 15 *F - even before the flush?

It seems like some are getting confused by my procedure. The last flush left 15.5 quarts of distilled water in the system when the pet**** quit draining. I then added 2 gallons (8 quarts) of pure Ford Gold Antifreeze.
8 quarts/15.5 quarts = 52% Antifreeze / 48% Water
I continued filling the coolant reservoir with a 50/50 mixture of Ford Gold Antifreeze and distilled water until the reservoir was full.
I checked my freeze protection using a coolant tester and it indicated that I was slightly over a 50/50 mix as was indicated by the freeze protection of ~-42deg F. A true 50/50 mix will yield a -34deg F freeze protection.

I think your reading with the coolant tester is correct. You will really never get all the antifreeze out of there... You calculations are not correct though.
50/50 is: half the capacity of the coolant system is water and the other half is straight antifreeze. Not 50% of the water left in the engine after you drain the radiator (thats where you got your 52/48 - 8 divided by 15.5). If you have 15.5qts of water and only 8qts of coolant you have 29.09% coolant in there (but there is still some old coolant in the "clear" water). It is essentially 50/50 of the 27.5 quarts not 50/50 of the 15.5 quarts.
Did you run the heat when you were heating it up? If not then you still had old coolant in your heater core.

I have a coolant filter. I changed the filter after my flush / refill procedure. I didn't see any sediment / deposits coming out while draining nor in the filter when I cut it apart. Since I didn't see any deposits and my EOT / ECT hasn't varied by more than 7-9 degrees, I do not think I will redo and flush with the VC9.
Thank you bondsman, I was just getting ready to do that. Also, are you testing the coolant in the tank? As the 50/50 concentration that you last put in may not be mixed with the rest of the coolant yet; you should test it from the pet****. Not to Hi-Jack but since so many people are watching this thread, what kind of filter systems do ya'll like best? And to help me not be an anal retentive ass what's the most efficient, quick and dirty way to change coolant if you plan on doing it every year. Thanks in advance, Eli.
I just had a re placement thermo stat + a power flushing , by the dealer. ( now there is a good chance i will have heat .
The dealer worksheet / invoice states they put in 2 gallons of gold.
I was thinking thats not enough , not sure.
**********************************
New NAPA anti freeze tester. Hey it was $9 and i wanted to know about my freeze protection situation
Tested from pet**** into small clean container Yelded freeze protection to minus 35-45 F
So i guess i'm good to go , and the dealer may have done it correctly. Corrosion protection and exact pure coolant percentage vs water , i dunno. At least it will not freeze.
I did a small container of 50-50 mix while i had my handy dandy tester out , just for giggles. 50-50 yielded -25F protection But most likly would not have the corrosion protection that seems nessisary in these engines.
thats all i know about that.

My apologies - I did not read it that way. Good job!
your math should be 8qts out 27.5 not 8/15.5. if you take 15.5/27= 57% water and 43% antifreeze.

new 06 PSD same as above only it's a Lariat, this one started puking as well.

He left 15.5 quarts of pure water in the block after flushes - undrainable.
He added 8 quarts of pure antifreeze.
So far he is close enough to 50/50, but the system is not full yet.
He finished filling the system w/ a 50/50 mix.
this math is good for a 50/50 final mix.
