SJM does specify the cross bar to be vertical.

His question was about an arrow. SJM doesn't specify arrow

from SJM's site:

Install the thermostat with the cross brace vertical, orientated at 12 and 6 O'clock

I was wondering if there was an arrow on the thermostat, this info is just as good.

I'm glad I went back in to turn it the way Bentley was showing it.

OK, so final conclusion is:
for 20V - vertical;
for 32V - horizontal.

I hope to never have to change the thermostat again... huge PITA!!!

Prior to replacing my thermostat, my temp gauge was hovering just under the large hash at 11:00 at idle and would drop if I hit Auto on the CC or started driving. Heat was somewhat tepid but I didn't think anything of it since I had the temp set to 66 degrees.

with the new thermostat, I get up to normal operating temp in about 5 minutes of driving. The temp stays at slightly above the large 11:00 hash mark and the heat comes on strong and hot even though it's set to 66degrees.

I'm currently experiencing a 3-4 mpg improvement and expect that average to drop down to 2-3 mpg improvement once I work some heavy footery into the mix.. but I did replace the coolant sensor at the same time.

so prior to thermostat replacement, I was getting around 14.5 mpg on 2 days of short conservative driving style trips in town and today I'm looking at 18.5mpg.... not terribly scientific or even consistent but a definite and clear difference.

I should pay myself back for the parts and labor in a short time if the mileage improves with the warmer weather in the spring.

interestingly, Boost is the same as before, but the car feels much more lively. I guess it's timing related but who cares.
