Study Notes

Engine Compartment Inspection

Check for leaks and conditions in the engine compartment with the engine off; look for puddles and dripping fluids.
Confirm oil level is above fill mark, located using the dipstick.
Inspect coolant level in the reservoir or radiator cap when the engine is cool.
Verify power steering fluid level is adequate and above fill mark, using the appropriate dipstick.
Assess the condition of belts (power steering, water pump, alternator, air compressor) for snugness, cracks, or frays. Identify any components not belt-driven.
Ensure components such as power steering, water pump, alternator, and air compressor operate properly, are not damaged, leaking, and are mounted securely.

Cab Check and Engine Start

Perform a safe engine start by depressing the clutch and ensuring the gearshift is in neutral or park.
Verify the oil pressure gauge functions; it should show increasing or normal oil pressure.
Confirm the temperature gauge is operational, with readings climbing to the normal range.
Check that the air gauge builds pressure to governor cut-out, around 120-140 psi.
Ensure ammeter/voltmeter shows the alternator or generator is charging; warning light should be off.
Mirrors must be clean, adjusted properly from the inside; windshield should be free of obstructions and damage.
Emergency equipment should include spare fuses, three red reflective triangles, six fuses or three liquid burning flares, and a properly charged fire extinguisher.
Check for steering play: Non-power steering should have no more than 10 degrees of play; power steering should also be under the same limit with minimal wheel movement.
Wipers and washers must operate correctly; check wiper arms and blades for security and smooth operation.

Lights and Horn Functionality

Test dash indicators for left/right turn signals, four-way flashers, high beam headlights, and ABS indicator to ensure they function correctly.
Inspect all external lights and reflective equipment (clearance lights, headlights, taillights, and reflectors) for cleanliness, functionality, and damage.
Confirm the proper operation of the air horn and/or electric horn.
