Engine Block: Description
WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, and 2003 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
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 for- ward. 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.
