Despite years weekly inspections under the hood, I noticed something
about the coolant tank tonight that I'd never noticed before.

I always look at the end of the coolant tank to check the level - where
it says "Cold Fill Max/Min ". I just realized that inside the tank,
immediately to the left of the pressure cap, there is an internal
vertical divider. And all of the tank that is on the right side of this
divider - which comprises about 75% of volume of the tank - is empty !!!

What the heck is up with that ? What have I overlooked all these years ?

The coolant bottle has two chambers. The Coolant will normally only be in
the inboard (smaller) of the two. The outboard chamber is only to recover
coolant in the event of an overheat or after a recent service fill. The
outboard chamber should normally be empty.

Phew ! Thank you Glenn.

How would coolant get into the outboard compartment after a recent
service fill ? Is there an overflow weir or passage near the top on the
inside ?

I also notice that molded into the top of the tank, there is mention of
using a special Miller Tool for "proper fill". What's the deal with that ?

Thanks again....Phil

I think it's the tool to bleed air out of the cooling system where it
gets trapped in the block/heads when you drain the coolant and refill.
