The engine temp is 180 deg. The upper level of the engine room is probably 200 while the lower may be 120 . Lectrosan as I recall does not allow discharge in our area . That may not be true where you are . To get accurate temps get a infared heat reader , about 100 bucks . these give instant temp by pointing and hit the button . These devices are great for engine diagnostics ,you can spot a stuck thermostat by watching temp rise at the hot spot and cool on the other side . Also can be used to verify instruments accuracy .
