Don't know if this has been posted before or not.


I am replacing this as soon as I head out the door after typing this. My normal temp is around 194 degrees based upon my H&S gauge and I haven't noticed any coolant loss but I also have only 46k miles on my truck


I hope once I put this on I do not have new issues pop up b/c the next weak link gives.

$5 PART WILL SAVE YOUR POWERSTROKE FROM SELF DESTRUCTION - YouTube

 

I saw that too and it is a very interesting find that I haven't seen on any of the forums....

 

I think Im going to pick up a new cap today at Advanced Auto. I was going there anyways, so for $5, I might as well.

 

There has been some discussion on degas cap replacement, but this is a great explaination. I will go purchase a new one Now!

 

I plan on buying one on the way home today. I will then check to see if I have one of the newer caps already installed. If I do then I will hold on to the one just purchased, just in case.
Interesting video. great information. Any further research out there on this issue?

Where do I get it? What kind of brand? Can I get it from ford?

 

WOW if ford is putting an inferior cap on to begin with I would not put another ford cap on

 

Great Info! Just looked at the cap on my 2008 6.4L, and it's one of the old type. Picking up a new one this afternoon.

 

Getting this when i pick up my truck today from the body shop.. advance auto parts is on the way... i'll be replacing it today.. i wonder if this is whats causing my puking problem when i get close to 40+ lbs of boost

 

As well as the cap I suggest a light sanding...very lightly where the cap goes before you put it on.

You want to ensure it is smooth and free of any coolant and rough edges.

Does not take much.

 

Just got mine

 

Just ran out to the shop and checked mine, old cap and a little residue of coolant dried around top of resevoir. New cap tomorrow.

 

I am going to check mine today!

 

Checked mine last night , had the old cap, stopped and picked up the new cap yesterday and took it out for a test drive! New cap holds pressure no problem... The last cap wouldn't hold the pressure just like explained on the video ! I was able to boost all the way up to 45psi according to my livewire without issue ... I thought for sure my head gaskets were gone a few weeks ago ! But this simple $5 part saved me a TON of $$$$! I reccomend this cap to everyone !

 

At the OP, great post, thanks for the info, will be checking my cap today!
