What is the correct mounting position of the thermostat jiggle valve for a 2003 Buick Lesabre with a 3.8L engine. Is it 12, 3, 6 or 9 o'clock?
Thank you.

you could speculate that the plane of the thermostat will have a bearing on the valve position. a horizontal installation would benefit from a 12 position since air rises to top.
