Lube oil accumulating in the cooling water system of a diesel engine will result in __________.

Question 1 of 27070

Lube oil accumulating in the cooling water system of a diesel engine will result in __________.

🔍 Key Concepts

• heat transfer between engine metal, cooling water, and lube oil • effects of oil contamination in a water-side cooling system • difference between heat transfer problems and mechanical failures (cooler, lubricator, camshaft)

💭 Think About

• Think about what happens when oil mixes with or coats a cooling-water passage—does that improve or reduce its ability to carry heat away? • Which of the listed failures would be a direct and immediate consequence of oil building up in the cooling water side, not the lube oil side? • Ask yourself: is the problem more about removing heat from the engine, or moving/measuring the oil mechanically?

✅ Before You Answer

• Identify which option describes a heat transfer effect, not a specific part breaking • Confirm which component(s) actually touch the cooling water side versus being on the lubrication side only • Verify which outcome would be the first logical consequence of insulating the cooling surfaces with oil
