Question Elevation affects coolant level?

Can anyone tell me how much the coolant level would be effected by a change in elevation?

Eg: Would going from sea level to ~1,500m (~4,900ft.) on a road trip cause the overflow tank to expand all of the way near the top?

No, it shouldn't.

I've driven many long distance trips, over the rockies and the continental divide and have had no issues like you speak of.

Same answer. I drive from Oklahoma to Window Rock at least twice a year, going from under 2000 feet to almost 7000. I also drive around the mountains of southern Colorado several times a winter. I've not ever seen the problem that's described here.

Thanks for the input guys.

They say it all checks out. The pressure tested it, ran it up the local mountain to the ski hill and the radiator itself is full as it should be, no matter what the level is in the overflow tank. So it doesn't look like it's an air bubble or clog in the system to keep the coolant from flowing. They installed a new block 3,500 miles ago under warranty, so it's not like the water pump is shot or anything, and the gaskets can't be blown already. The heads are from my old engine and were resurfaced. In any case if it ever does overheat (like it used to on the old block) when I let it idle, and throws a CEL, then I'll be going back and pissed. They're going to mountain fight it this afternoon again just to make sure.

I think what they said about the coolant expanding, related to elevation is a bit BS...

I've noticed on the TS wagon i'm driving today, the coolant level only rises about an inch in the overflow tank when driving around town.

Any more input?
