The cap must be fully tightened to prevent loss
of engine coolant (antifreeze), and to ensure
that engine coolant will return to the radiator
from the coolant expansion bottle/recovery
tank if so equipped.
The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces...
The Trac-Lok rear axle provides a constant
driving force to both rear wheels and reduces
wheel spin caused by the loss of traction at one
driving wheel. If traction differs between the two
rear wheels, the differential automatically
proportions the usable torque by providing
more torque to the wheel that has traction...
