What does this diagram show?

It is a cutaway illustration of a V-type engine showing fluid flow paths, with red and blue arrows tracing circulation through both cylinder heads and the engine block — consistent with a coolant flow diagram.

What do the red and blue arrows indicate?

The arrows show the direction of fluid flow through the engine: red arrows mark one flow condition (typically hot coolant) and blue arrows another (cooler fluid), routed through the heads and block.

Are any specifications, part numbers, or labels included?

No. The scan contains no legible text, legends, part numbers, or torque values — it is purely a pictorial flow illustration.

This document is a color cutaway illustration of a V-type engine, apparently depicting the coolant (cooling system) flow circuit. Red arrows trace the path of hot coolant and blue arrows trace cooler fluid as it circulates through the two cylinder banks, cylinder heads, engine block, and connecting passages toward the front of the engine where the water pump and thermostat area would be located. The drawing shows both valve covers removed/sectioned so internal galleries in each head are visible, with cross-hatched red and blue regions indicating flow direction within the heads. The illustration was uploaded to a 1993 Mazda MX-3 gallery as part of a multi-page set (filenames miller02 through miller09), which suggests it comes from a factory service manual or technical reference covering the MX-3's V6 engine cooling system. No text, legends, torque values, part numbers, or year/model statements are legible in the scan, so the vehicle applicability cannot be confirmed or contradicted from the image itself. A reader can learn the general routing of coolant through the engine's heads and block from the arrow diagram, but no specific specifications are provided.
