Another taxi test was performed, this time watching the coolant temps closely since they were a bit high last time when running with the top cowl off. This time, we kept the top cowl on to keep airflow as it would be during normal taxi, and the results were very good. Coolant temps remained within the green. Outside temps were about 10 degrees cooler (87) than the last test, but coolant temps varied between 204 and 217 during taxi test which was over 35 degrees cooler than the last test.

Also, we double checked the fittings that were tightened last time (at bottom of left fuel tank, and at bottom of header tank). No fuel seepage was detected so looks like these are now fixed.
Lastly, we attached a small zippered plastic pouch to the left footwell panel which will hold our airplane registration and other documents that need to remain in the airplane. Hours: 3
