I've temporarily re-installed my coolant recovery container (I found a spot) as a catch can.
Added 2 qts water to Expansion tank, measures 2 1/8" from bottom of tank.
Went for long drive. After letting it cool down, measured water level @ 1 3/4 ", maybe an ounce or two in catch can. Missing water maybe was in the form of steam escaping ?
