Just would like info on what coolant is the best to use on my 06' Six-O,,,Going on 45k miles now,,and see some posts about it should be changed,,,,now apparently !

If I let Ford do it,,,I wont have to mess with getting rid of the old Coolant,!

Last time I let them touch my truck,,,I had oil spots all over my driveway,,,(oil change,,drain plug leaked)

Lets hear some opinions on what type of coolant is preffered for the Six-O.

Thanks to all,,,,,,Mark

 

Motorcraft Gold coolant and distilled water in a 50%/50% ratio.

 

or Valvoline Zerex G05....its also 100,000 miles gold color coolant. Meets Fords spec. Cheaper.

 

Here is what you do....

1) Buy 4 gallons of Ford Premium Gold coolant at dealer.

2) Buy 15 gallons of distilled water at local grocery store.

3) Drop lower radiator hose until empty.

4) Reconnect hose and add distilled water to degas bottle until full.

5) Drive truck until temp guage goes to normal and thermostat opens.

6) Repeat steps #3 through #5 no less than 4 or 5 times (depends on distilled water amaount used) - I can't remember?

7) You now have 100% distilled water in you system.

8) Drop lower radiator hose 1 last time, drain and reconnect.

9) Look in manual for your system capacity and for a 50/50% refill of coolant just add the coolant straight into your degas bottle up to the amount that equals a 50/50% concentration.

10) Start motor and add distilled water to bring system level to the MIN mark on degas bottle (do not add coolant as you already added 50% of the total capacity of the cooling system).

11) Drive truck around to open thermostat and let cool once or twice to purge any air. May need to add more distilled water... but when done you have flushed your entire system and have a perfect 50/50% concentration of coolant and distilled water!!!!

I did mine at 50,000 miles, 105,000 miles and is due to do it again at 150,000 miles. I do every 50,000 and never worry about testing for nitrates or other stuff. FYI - I also use a dieselsite.com coolant filter for extra protection, but that is an entirely different topic/thread.

The dealer only uses tap water and so does most other places... distilled is best in order to keep the minerals out of your system.

Good luck,

 

Do you think R/O water would be ok or would the PH be too low?

 

Not sure what RO water is????

Just use distilled water... all minerals removed and costs less than $1.00/gallon.

 

Reverse Osmoses.

 

I do not think this would work.

RO is just highly filtered water, but minerals are still left in it.

Distilled water is water that has been "super-heated" to make steam and then as the steam cools it is captured. The minerals and other impurities are "cooked off".

This is why distilled water is used in all appliances and is factory-fill by Ford... for reduced mineral content and less "fouling".

I also assume that the companies that make distilled water are also filtering to some degree if not RO as well????

If money is an issue, I would use RO instead of tap water... but for only $15 - $20 I would just buy distilled water at the grocery store and not worry about it.

 

gotcha!

Thanks! I have an R/O system at home so the wheels were turning..... You know how that goes. I will get the distilled.

Have a good weekend!

 

U wonder why they bother with all the crap they leave in the block and don't include a coolant filter. Think they missed the boat. Could have factory installed coolant filters and made a killing on filter sales like they do on all the other filters.

 

I would not use Ford Premium Gold coolant the anticorrosion does not last
and you can't add additives to it this will lead to failures. There a lot of other suitable coolant that would work.

 

Such as?

 

Motorcraft Premium Gold or Zerex G05. Don't use anything else. These coolants meet specified Ford standards and they work well. Using anything else is risking problems (that will become major eventually) before you ever know that they are going on.

Why would you even need to experiment - you have two legitimate choices. One of them is readily available. They last a long time - even Ford says so.

 

Would be nice if people like this could post scientific proof to back their statements. Ford is recommending the addition of vc-8 depending on nitrate levels. Still, blank statements are like drunks. Will it be remembered tomorrow.

 

In the trusty owners guide it says{do not add extra inhibitors or additives to the coolant} but maybe Ford came out with a bulletin because the found out that they where having issues like the last bulletin that i am assuming every on got where Ford says how to stay on top of PM which includes doing coolant samples. My coolant after 3-1/2 years and 30k nitrite levels where at 0ppm. I change it to a coolant that exceeds Ford and it allows you to add SCA maybe that is why people have had troubles with failures from corrosion.
