Im sure its in here somewere but dont forget to use DCA!!(diesel coolant additive). I would highly recommend Redline water wetter. Prevent cavitation etc. and keep your coolant temps happy. Test strips are available at all autoparts stores and so is additive.

 

just to clarify, that only applies to a 7.3

DO NOT USE A DCA on the 6.0 or newer PSD!

 

You may want to read a little before throwing down a gauntlet you can not defend.

Just sayin'

I am glad to know you were here "when the earth was flat" tell us about it?

Which of the small block chevys had no provision for an oil filter...the 265 cid or the 283 cid? Or was there another...please enlighten.

Do you think the reason cars did not have 'cabin filters' was because...they did not have air conditioning? Because they had this thing called "cowl induction." Oh, and a little history lesson that's just the last 50 years. The previous 50 years they were pretty much open air.

Show just a little respect (to Snowseeker) before making provocative comments that will only get you rejoinders like mine...and I am the nice guy.


Hope you get your EX on the road soon.

 

To clarify even further, only use a Supplemental Coolant Additive (SCA) for a 7.3L that is filled with a traditional "green" coolant.

It's not a bad idea to check the SCA's if you're running the Ford "gold" (H-OAT coolant) or the Zerex G-01 gold/yellow colored coolant (same as the Ford "gold"), but usually it isn't necessary unless it has a lot of miles on it.

As for a heavy duty OAT coolant meeting Cat EC-1 specs, DO NOT ADD ANY SCA's to the coolant. You also do not check it with test strips.

Aww shucks, I'm not used to someone defending me.

I would like to add to my earlier posts that I will agree it would be a good idea to add a filter to a 6.0 if you just got the truck and it never had any work done to it.

Now if the motor has been torn down for gaskets and such I honestly don't see much use for the filter since most "stuff" should be well flushed out by then. Like my truck, at 188K miles I don't think there is much casting sand or junk left in the cooling system. If it hasn't had a coolant problem by now I am pretty confident it won't ever will especially after being all drained, taken apart, rotated a bunch of times, and whatnot. Personally I would rather skip the added lines, connections, and parts that could possibly cause a leak or issue. But also like I said if I just bought a lower mile 6.0 without any problems and were just going to drive it I would be tempted to install a filter if even just for a year or two just to see if there is any junk floating around and to make sure the system is clean. But if after a couple filter changes and all the debris was gone and there was nothing caught in the filter any more I would be tempted to pull the filter system out and put it back to stock. But once again here everyone has their own opinions and ideas and I am sure many would want to have and leave the filter in all the time.

Besides, a little debris in the coolant keeps the coolant passages walls clean.

 

But the oil cooler's coolant passages are where debris can collect, and it is way easier to replace a spinoff coolant filter..

First, let me say I am sorry if I came across as an *** but it's me that has a problem. From an early age I have always gotten bent when I was told to do it this way because that's how it has always been done. B.S. I'm not a kid any more and I'm free to voice my opinion. I don't much care if I'm not one of the cool kids. I normally refrain from responding to posts that I find irritating. There is nothing to defend in my first post. I responded to a statement by pointing out that his signature contradicted the statement he just made about OEM being perfect.

Statement made.

Signature line.

Both vehicles show mods to fluid systems. I may not be part of the in crowd, but I can read. OEM is not perfect. If it was, all of these fixes for the 6.0 costing thousands wouldn't be necessary. I saw a 2003 F250 last week with the cab off and the motor torn down. The heads were cracked. It was getting the whole bulletproofing treatment with new heads. Price tag, over $12,000. If a coolant filter had been installed, could it have saved this poor guy from tearing his truck down? Who knows, maybe.


I will reply to my second post later. Just sayin'

 

Leave the air filter alone, do not replace it with K&N filter, if your Ex is a 6.0 PSD.

 

Or on a 7.3
