Coolant Level

Help me out. I know per the new tsb the coolant level at normal operating procedures should be at the min mark. Now here is what I'm seeing. At cold obviously the level is below the min mark. Mine is roughly about a 1/4 in below. When hot it's just under the min mark, but if I unscrew the cap (slowly of course) to add a bit more water (distilled) it'll raise up to the min mark. So is this good or do I add? Help.......

Mine stays about the same as yours. I just look at it to make sure it doesn't go down any.

I would honestly leave it as it is. My coolant level changes because the system holds quite a bit of fluid that you can't see. How long do you let it set to be "cold"? You'd be surprised how long that stuff actually stays warm. I've left the truck for a day and a half and 2-3 days and the levels were different from each other.

I guess my question is, is normal operating procedures with or without the cap on? Because with the cap on it's under the line, with the cap off it's at the min line?

I turned my truck off last night around 7:30 and didn't start it back up until 7 this morning.

That cap needs to be on. Imagine overflow without that cap on, it'd probably flush the majority of the system out.

That's really not that long to set. If you can, let it sit an entire day/day and a half and see where you're at. I'm saying you're fine where you're at.

topdwg, i see you have an EGR Delete and you are not burning coolant you are just not happy with the line. This is my opinion, winter is coming, top the bottle off with some ELC (Flush and refill if thats what your looking to hear) and call it a day. You have coolant in your degass bottle it is just up and down with the level by a 1/4". Not an issue in my opinion. I have pulled my cap off and watched the level go from the min line to well below it then put the cap back on started it let it run and the level is back.

No coolant comes out. Do a slight turn and the air will start to come out. While it is the coolant starts to raise. By the time all the air is out and the cap is off the coolant is at the min line.

So while the truck is pressurized (cap on) it should be at the min line?
