70% to passWhich of the listed diesel engine operating conditions should be checked immediately after any diesel engine is started?
ALube oil pressure
BExhaust temperature
CLube oil level
DWater level in the expansion tank
AI Explanation
The correct answer is A) Lube oil pressure. After starting a diesel engine, the first thing that should be checked is the lube oil pressure. This is critical because proper lubrication is essential for the engine's safe and reliable operation. Low lube oil pressure can indicate a problem with the lubrication system, which could lead to engine damage if not addressed promptly. The other options are not as time-sensitive. Checking exhaust temperature, lube oil level, and water level are also important, but they do not require the immediate attention that lube oil pressure does after engine startup.
