What visual cue can indicate engine or transmission leaks during an initial inspection?

• A. Looks for puddles
• B. Listening for noises
• C. Check coolant level
• D. Observe tire wear

Answer: (A)

Visual cues are the quickest way to spot leaks during an initial inspection. A fresh puddle under the vehicle is the clearest sign that fluids are escaping from either the engine or the transmission. This visible evidence is reliable because it shows a leak without starting the engine, and you can often infer the general area of the source by where the liquid pools or leaves a stain. While other checks have value—listening for unusual noises can indicate a problem, coolant level can drop with a leak but doesn’t show the leak itself, and tire wear relates to traction and wear rather than fluids—they don’t provide the immediate, observable confirmation that a puddle does.
