🔍 Key Concepts

• Use the color key at the lower left of the illustration to identify water components first • Distinguish between a manifold (a common distribution pipe that feeds several points) and a single connection or valve • Follow the blue flow arrows to see where cooling water first ENTERS the engine before circulating around the cylinders

💭 Think About

• Look along the sides of the engine for a long or shared blue passage that could supply cooling water to more than one cylinder—does any letter/number point to that? • Compare the blue parts at the top and the bottom of the cylinders: which looks like an outlet carrying heated water away, and which looks like an inlet bringing cooler water in? • Ask yourself: which label is on the main blue distribution line, not just a local jacket or individual fitting?

✅ Before You Answer

• Confirm your choice is pointing to a blue (water) component according to the legend • Make sure the labeled part is a common line feeding multiple cylinders, not just a single pipe or bracket • Verify that flow arrows at that point show water entering the cooling spaces, not leaving them
