Oh... I guess I did forget to state my point in the post above....

The point is.... using common sense and changing fluids makes for a good performing motor and truck that will last.

I know that brake fluid collects moisture and one needs to get rid of any contaminants and moisture to prevent premature wear of the braking system.

I know that clean fresh p/s fluid prevents excessive wear of the power-steering system... and its cheap and easy to do.

I also know that pulling and even normal driving will one's diff's down and changing fluid will keep it running cooler, quieter and performing as designed.

I also kow that changing one's coolant allows for maximum protection and removes any "deposits" that built up over time.

The point is.... common sense and changing one's fluids early (regardless of what the marketing and engineer's state is good practice). We have all been changing coolant every so many miles and years previously... and I believe that there is no special chemical out there that will last for 100,000 or forever... I guess Ford is just now finding this out!!!

I also use PowerService fuel additive in every tank and use it for the increased cetane boost and lubricity properties... even though Ford stated in the old manuals to NOT use any... then they revised it and even started selling their own additive.. so I guess they learned to that lubricity and cetane boosters are key!!!

 

So very true... if one's coolant is low on protection one is to flush and refill with the proper fluid to maintain proper protection.

Just adding some "additive stuff" is not what the notice states if below 300ppm... and heck... if mine was running low but still acceptable.... I think I would still just flush it with distilled water and refill with new Premimum Gold coolant.

 

I'm just curious that if you r running a coolant filter how important is this iron cleaner??

 

Last July I had my truck state inspected at the dealer and I had them change the coolant at 103,400 I had test strips but never bothered to check the nitrite levels. I never bothered checking because I was under the impression you didn't have to with 6.0's using the Ford Gold coolant. I would check my 1989 IDI and my John Deere 332 sometimes 2 times a year and would have to add some NAPA additive. Last week I check my coolant on my 2003 6.0 at the degas bottle and at the petcock and both readings showed the same at around 1200 PPM nitrite level after 12,000 miles since the change. Then I went in my basement and mixed a cup of 1/2 and 1/2 distilled water and Ford Gold and I got the same reading as whats in my 6.0 but I would bet the dealer used tap water instead of distilled. Since last fall I have changed my 7.3IDI and the JD 332 over to Gold and I get the same readings. Maybe other people can chime in on their nitrite levels after 75,000 miles with the original factory coolant to see if the levels went down from age and miles.

 

Where can i get some nitrite test strips. I dropped in at the dealer and they told me they don't carry them.

 

Fleetguard DCA4 Test Strip Kit CC2602A (FleetPride or DieselManor). NAPA also sells them.

 

Some NAPA stores also sell Wix coolant strips, I would buy the least quantity package available because there is a shelf life on them. The only one available to me at the time was a bottle of 50 which was around $20. I got them 1 1/2 years ago and they will expire 11/09 with about 30 left.

 

I don't have my diesel supplement manual. Can someone tell me how much coolant I will need to do the flush on my 2005?

 

Coolant system capacity is 27.5 quarts plus a little if you have a coolant filter.

Is it safe to add the additive to Ford's Coolant? I am going to check mine but I remember the 7.3L guys had to add something to the coolant. Should we be doing this too?? I use fuel additives every tank. I only have 50,000 but I plan on a coolant change next oil change. Trying to keep up on maintenance I need this truck to last a long time.

Additives are not required when using Ford Premium Gold coolant with the 6.0 PSD. Keep if changed as required and you'll be good to go. I think the recommended interval is 100K for the first change and 50K after that, however I do mine every 50K.

 

I agree... I change every 50,000 miles and never worry about it. I thought Ford's service interval was to good to be true... I think I have been proven right?

By the time we buy the test strips, add or change as needed... one may as well just change/flush their fluid with distilled water and new Ford Premium Gold coolant.

(That's my story officier and I am sticking to it)
