Cylinder Block Drain Plug
The coolant drain plug is located on the rear left side of the cylinder block.
On vehicles supplied with a cold climate package (i.e. vehicles operating in conditions regularly below -30°C) a cylinder block heater unit is fitted instead of the drain plug.
Engine Lubrication
Oil is drawn from the reservoir in the oil pan and pressurized by the oil pump. The output from the oil pump is then filtered and distributed through the internal oil passages.
Where an oil cooler is fitted, the oil is cooled before entering the filter.
All moving parts are lubricated either by pressure or splash oil. Pressurized oil is also provided for operation of the variable valve timing units and the timing gear chain tensioners.
All of the oil system components are installed on the structural sump.
Oil is returned to the oil pan under gravity through large drain holes in the cylinder heads and the engine block to make sure quick return of the oil.
