Right now the car is cooling down. When it is cold again, I will
repeat the process correctly.


Update - the car cooled down.

I repeated the procedure and followed directions.

I let the engine idle, with the pressure cap off, until the upper hose
was hot. Then I opened the bleeder valve.

The coolant spurted with air for a few seconds, then ran nice and
steady with a solid stream of coolant. I closed the valve and replaced
the pressure cap.

Lots of heat from the blower. A 15 minute drive showed no signs of
over or under heating.

It worked!
