The engine block is the foundation of an engine. Most engine blocks are cast from an aluminum alloy, but iron is still used by some manufacturers. The engine block is also referred to as the cylinder block because of the big hole or tubes called cylinders that are cast into the integrated structure. The cylinder is where the engine’s pistons slide up and down. The more cylinders an engine has the more powerful it is. In addition to the cylinders, other ducts and passageways are built into the block that allow for oil and coolant to flow to different parts of the engine.
The engine harness is typically a large bundle of individual wires protected by a shell of insulation and conduit which helps to protect it from the elements. It is often asymmetrical, with the large end close to the fuse box and becoming smaller as it branches out over the engine. Since the various automobile manufacturers have different engine designs which also change over time, engine wiring harnesses are often unique to the year, make and model of a vehicle. Because of its proximity to the engine as well as contaminants on the road, engine wiring harnesses can degrade and require repair or replacement.
