Engine Block: Description
WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
The cylinder block (6) is made of heat treated aluminum with cast-in-place iron liners. See 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 main caps (2) each with 6 bolts 4 vertical (1) and 2 horizontal (5). The engine is equipped with a 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.
