The lube oil coolers installed in a gravity lubricating oil system are located between the __________.

🔍 Key Concepts

• Flow path of oil in a gravity lubricating oil system from sump to bearings • Purpose and best location of a lube oil cooler in relation to pumps, tanks, and machinery • Difference between pressure side (pumped) and gravity side (downhill flow) of the system

💭 Think About

• Trace the complete path of the lube oil starting at the sump and ending at the main engine bearings. Where along this path would cooling be most effective and easiest to control? • Think about where you want the oil to be at a controlled, stable temperature: before it is stored in a tank, or just before it reaches the bearings? • On which side is it better to place a cooler: where the oil is under pump pressure, or where it is just flowing by gravity?

✅ Before You Answer

• Identify clearly which components are on the pressure side (discharge of the pump) and which are on the gravity side (downstream of the gravity tank). • Confirm whether a cooler works more reliably with steady pump flow or with low, variable gravity flow. • Double‑check which option places the cooler where the oil is being actively circulated, not just draining back to the sump.
