6.0 Coolant Level

[jd4010]

Want to confirm what I've read on other sites....that the "new" max is the min line on the coolant degas bottle. If I read these other threads right, the level should be at min when at normal operating temp.

Thank you....just trying to avoid puking.

yes that is correct

Unless you're runnin Evans Waterless coolant...I fill that sucker all the way to MAX, no more sporadic cold spots out of the heat vents in the winter !

All liquids expand when they heat up. Since this is a pressurized system, you need a fair amount of vapor space or the pressure build can be too high (and you puke). The fill line is the minimum line. You will have no adverse performance issues from doing this.

No boily, no pukey.

Sorry, but that is not correct. you can easily do the liquid expansion calculations and see what 100 *F temperature rise will require in volume to keep the pressure from rising beyond 16 psig. It is between a quart and two IIRC.

Well chemistry class aside, I haven't had problem one since switching . Engine actually runs a little hotter (good) without overheating or puking.
The de-gas bottle is a bit higher when hot, but all good. And the other benefits are lifetime coolant without additives, no water, no rust, no scaling, and alot higher boiling point.

To each his own...

dont mean to hijack the thread but my coolant was a little low the other day (and with this being my first powerstroke) i added a little of the advanced auto green (ethalyne glycol) but heard u had to use only propylene glycol. I planned on getting a coolant flush tomorrow but what do i have to worry about with this crap? Ive only driven about 200miles since with no loads

The factory fill coolant is Ford Premium Gold. It is not propylene glycol - it is ethylene glycol. This misconception seemed to begin on Powerstrokehelp.com.

The green coolant will absolutely NOT protect your system from corrosion. Also, if you mix the green with the gold, you stand a very good chance of precipitating out silicates which will plug your oil cooler.

Flush it soon and use the VC-9 cleaner from the dealership.

Some folks are using the ELC coolants recommended by Navistar and seem to like them. As posted, lordVader likes the Evans (several others have also posted they like it). Hopefully they are effective in corrosion protection. Only long term usage data will tell.
