[s-cars] No Heat at Idle?

[Bob Rossato]

By raising the level in the reservoir you provide a little more force
due to the additional coolant, which will allow a small portion of any
existing pocket of air to be displaced through the system.  Once you
button up the system again and run the engine that small bubble will be
moved around until it makes it back to the reservoir.  So, if you do
have a pocket of air in the system the level in the reservoir should now
have dropped back down a little due to whatever portion of the air
pocket you displaced.  Repeating this a few more times you eventually
drive it all out.  At least that's the idea.

Now typically an air pocket doesn't just appear where none was there
before, so unless there was recent work done on the coolant system, and
the system wasn't filled properly, there may not be an air pocket.  But
it's worth trying to rule that out before digging in any deeper.
