Coolant 'burp' when degas uncapped

Hey guys-

2006, with SCT Looney, got the EGR and everything.

I've noticed the truck seems to have been running 10* warmer for the most part- AND

If I open cap on the degas, occasionally it will blarp out coolant, like there's air somewhere in the system pushing it out.

Coolant hasn't been needed to be added in the past 10K miles I've put on it, pulling a camper and such, and I don't see any sort of residue around the cap..

It should be noted I always fill it on my driveway, to the high mark, and that's at an incline so I might be overfilling..

Could this be the incipient stage of a headgasket issue? Or am I just paranoid?

I'm taking it apart now for the dummy plugs/standpipe/EGR/STC work, thinking about going all the way and doing heads now as well.

Greg

Is it the original cap or the updated ford one with orange writing and the yellow "updated fill line approximately a half inch below the old fill line?

It's the original.

Didn't know there was an update to that one- I'll have to pick it up, as I understand these things fail pretty often..

From my knowledge, they updated it to a lower pressure release to prevent the coolant burp.

The old caps purge at 15 psi, new ones at 16 psi. If the cap pops when you take it off, thats normal, if it feels like its about to take your hand off, thats a sign to at least test coolant psi. If its bubbling air into the degas, it might be from either two small hoses going into the top of the degas but shouldnt be. If you are getting air into your block, thats very bad. That might mean a pump issue??? (Someone else might answer that), or a common problem, one I noticed with ELC type coolant, is that less than 50/50 can flash boil inside the block, causing air pockets. I always use the old fill line and even with a bad HG it never ever "burped" it just shot the cap off everytime I opened it after driving. I would try to isolate where the pressure is coming from, and look at making a $20 collant gauge just to see (very crude, not something to keep on)

Good ideas.

I watered down the coolant pretty good when I had a coolant leak with my filter install...

I would get an electrolometer from autozone for like 2 bucks, compare the freezing pint with the chart on any coolant bottle, theyre all the same when it comes to freeze points. After I did my HG and studs I was running about 43/57 and I was still getting high psi, got it at 65/35 now and I cant get it above 8 psi. Hot tunes will increase the hotspt temps of your cylinders too. Id check your coolant ratio and go from there
