What would be the most likely indication that a shell-and-tube lube oil cooler had in internal leak permitting mixing of the two fluids?

🔍 Key Concepts

• Shell-and-tube cooler flow paths: which side normally has higher pressure (lube oil vs cooling water) • How a leak inside a cooler would show up in fluid LEVELS, not just properties • Secondary effects of water getting into lube oil (what else would change besides level)

💭 Think About

• If cooling water starts entering the lube oil side, what would happen to the lube oil sump level over time? • Which choice describes a primary, immediate indication you would see on your gauges or sounding — not a long-term consequence? • Which options could be caused by several different problems, and which one most specifically points to an internal leak in the cooler?

✅ Before You Answer

• Compare which system is typically at higher pressure during normal operation • Decide which symptom would be seen first at the engine, before damage or chemical changes occur • Identify the option that most directly reflects a change in quantity (level) rather than only quality (condition) of the lube oil
