Engine Compartment: Complete Verbal Checklist
The engine compartment is one of the most failed sections of the pre-trip inspection because it contains the largest number of individual components in a compact area and requires specific knowledge of each component's function and failure indicators. The complete engine compartment inspection covers: engine oil level (dipstick pull and verify on gauge), coolant level (surge tank level indicator or cap inspection, never open a hot radiator), power steering fluid (reservoir level), windshield washer fluid, battery (case condition, terminal corrosion, secure mounting), alternator and alternator belt (mounting, belt tension 1/2-3/4 inch maximum deflection, no fraying or cracking), power steering pump and belt (same criteria as alternator belt), air compressor (mounting, belt or drive gear condition, output lines), water pump and fan belt (condition and tension), air cleaner (secure mounting, condition), radiator hoses (upper and lower, no cracking, softness, or swelling), all drive belts (any cracking perpendicular to belt direction is a defect), block heater cord if cold weather (stowed and no fraying), and visible engine mounts for security. The verbal component requires stating each item's name, what you are inspecting for, and the result. Practice the engine compartment section separately from the rest of the inspection because it is content-dense and easy to abbreviate incorrectly.
