Cylinder Block Assembly: Description and Operation
DESCRIPTIONThe cylinder block is made of a sand-cast aluminum alloy. The cylinder block has interference-fit cast iron cylinder liners. The cylinder liners are thermally installed during block manufacturing; they are not serviceable items.
Six iron main bearing caps use four bolts per cap; two vertical and two horizontal. A windage tray is attached to four main caps via extended main cap bolts.
The block and heads incorporate a unique parallel coolant flow.
