š Key Concepts
ā¢ Cooling water flow path from inlet manifold, through jumpers, cylinder liner/head, to discharge manifold
ā¢ Color coding in the illustration: blue for water, green for scavenger air, yellow for lubricating oil, etc.
ā¢ Relationship between manifolds (common distribution/collection pipes) and the individual cylinder jumpers/passages
š Think About
ā¢ Start at the cooling water inlet manifold on one side of the engine: which lettered part clearly shows blue water entering a common header?
ā¢ Trace the blue water path from that manifold into the jumper pipes leading into the cylinder liner/head. Which letters mark those intermediate connections?
ā¢ Follow the water passages upward and out to the discharge manifold on the opposite side. Which letter or number labels that outlet manifold where the heated water collects and exits?

Before You Answer
ā¢ Verify that every letter/number you choose is actually marking a water (blue) passage, not air, oil, or exhaust.
ā¢ Make sure your chosen set starts at an inlet manifold, passes through a jumper, through the cylinder liner/head, and ends at a discharge manifold in the correct order of flow.
ā¢ Confirm that no item in your chosen set is clearly labeled for another system, such as fuel oil, lubricating oil, or exhaust.
