Engine Block: Description
The cylinder block is made of heat treated aluminum with cast-in-place iron liners (Fig 1). The block is a closed deck design with the right bank forward. To provide high rigidity and improved NVH, the block has cast-in contours and ribs, along with powdered metal 6 bolt main caps (4 vertical, 2 horizontal), with a die cast aluminum structural beam windage tray mounted to the main caps.
The block design allows coolant flow between the cylinder bores and an internal coolant by-pass to the thermostat.
