Installation: The bolt threads for the coolant pump,

the belt tensioning device, and the power steering pump
are not cut into a new timing case cover. For this reason,
use new self-tapping bolts in combination with a new
timing case cover for attaching the coolant pump, the belt
tensioning device and the power steering pump. Pay
attention to tightening torque with non-pre-tapped threads.
