Reading Your Results: G1 Auto Maintenance and Light Repair, Test 2
This test covers the same breadth as Test 1 but leans harder on the judgment calls maintenance work actually turns on: what a fluid is telling you, whether a part is worn out or simply out of adjustment, and which shortcuts create a comeback. Reading your misses that way is more useful than sorting them by system.
If you missed the questions about identifying a fluid
A leak is identified by the fluid before it is identified by location, because fluid runs and airflow spreads it. Red or pink and thin is usually transmission fluid or power steering fluid, amber to black and heavier is engine oil, sweet-smelling and not oily is coolant, and clear and slick with a distinct smell is brake fluid. That first call narrows the possible sources immediately, and it matters on a maintenance exam because the same drip near the front of a vehicle can come from three different systems. Confirming which system is actually down on level is what turns a guess into a diagnosis.
If you missed the questions built on a measurement
Three questions here compare a reading to a published figure, and each one is asking whether you know what the specification is protecting.
If you missed the questions about the right way to do the job
Several questions on this test separate the correct procedure from the shortcut that seems to work. Belt dressing quiets a squeal for a few days and does nothing about the tensioner or the glazed belt causing it. A fluid exchange moves fluid but does not remove the filter that has been collecting debris. A cooling system is refilled with the bleed point open so air can leave, because an air pocket produces an overheat that no amount of coolant fixes. A halogen bulb is handled by the base rather than the glass, since skin oil creates a hot spot that shortens its life. On the exam these questions are asking whether you know why the correct method is the correct method.
If you missed the EXCEPT and LEAST likely questions
Four appear on this test, and the method is the same one that works on the real exam. Identify what the three real causes share before you look for the odd one out. On the sinking pedal question, three answers all let fluid escape the pressurized side of the system, and one affects how the brake applies rather than whether it holds. On the refrigerant leak question, three answers are all evidence that refrigerant and oil are escaping, and one is a condition that appears with a full charge. Naming the shared trait first is faster and far more reliable than working through four options one at a time.
