Isolate the electrical supply to the engine. Remove
the filler cap. Check that the coolant level is within
25 mm (1.0 inch) of the bottom of the filler pipe.
Clean the cooling system filler cap (1) and inspect
the seal (2). If the seal is damaged, discard the old
filler cap and install a new filler cap. If the seal is
not damaged, use a suitable pressurizing pump to
pressure test the filler cap. The correct pressure is
stamped on the face of the filler cap. If the filler
cap does not retain the correct pressure, replace
the filler cap.

Crankshaft Vibration Damper -
Inspect
Depending on the engine variant the engine can be
equipped with one or two crankshaft vibration
dampers. The crankshaft vibration damper limits the
torsional vibration of the crankshaft. Damage to the
crankshaft vibration damper can increase torsional
vibrations. A damaged vibration damper can result in
damage to the crankshaft and to other engine
components.
