The thermostat set up is a fail safe. Bellows fail or cable snaps, flaps
are open. Thermostat pulls flaps closed when it contracts as it cools.
If the t-stat is fully expanded when cool, that means engine previously
overheated and melted the solder plug allowing air to enter and bellow
will stay permanently expanded.

Subject: Engine air control flap question (somewhat urgent :^)

Hi all.

  Am really enjoying road trip!

  Fairly urgent question.

  I'm travelling through Oregon now. OUtside temp is higher than
previous in WA.

  Cable connected to bellow for controlling air flaps in engine is
broken. Have removed bellow and hope to replace cable but...... I have
wired the flaps in what I believe is the open position to allow air to
cool engine better. (I assume bellow contracts, pulls cable and opens
flaps)

  Am I doing the right thing? It idles rougher when cool, but otherwise
seems fine. I want to keep things as cool as poss.

  Running an 81 air cooled 2.0 litre gas.

  TIA for any help!

  Neil Nicholson.
