Brief Description:  Engine Test With The Propeller

Plans:
1 Engine test with the propeller.
Status: Complete. A successful engine test with the propeller installed was performed. The objective was to determine if the coolant level is adequate and would circulate. Additionally that the engine operates in a safe temperature range. This test was conducted sitting in the cockpit using the controls and instruments. Idle RPM was 1200 however I cycled the RMP between 2000 and 3400 over several minutes per the manual direction. While doing this I monitored the indicated coolant level and temperature and oil temperature. I also used a handheld digital thermometer to look for hot spots in the engine compartment. The coolant temperature appeared to stabilize at 210 degrees F. Oil temp indicated a little under 200 degrees F. Using the heat gun I found that the hottest temps were generally 300 degrees near the exhaust manifold. Near the thermostat it was around 170 degrees. The coolant was circulating as I could feel the radiator and coolant hoses were hot to the touch.

While the test was successful I also found two issues. First is the overflow bottle for the coolant needs to be mounted more rigidly. Second it appears that the engine block is resting on the motor mount slightly.

The engine run-up was video taped. It is posted on Facebook.
