Fault

Remedy

(This column is filled in only if the
”probable cause” gives no clue as
to what must be done).

Probable cause

Coolant temperature
too high, coolant loss

Coolant level too low

Air in coolant circuit

Proportion of anti-freeze / anticorrosion
agent too high

Raw water supply clogged

Raw water supply insufficient

Cap with working valves on expansion
tank defective, leaky

Thermostat in closed position blocked

Heat exchanger heavily contaminated,
pipe group coated with foreign matter

V-belt for water pump drive not correctly
tensioned (slipping)

Water pump leaky, defective (bearing
damage)

Coolant circuit clogged by foreign matter

Thermostat jammed in ”shut” position

See ”Fuels, Lubricants ...”

Check inlet orifice

Impeller worn. Measure delivery
of raw water pump and vacuum
at inlet

Lube oil pressure
varies/too low

Oil level in oil pan too low

Oil level in oil pan too high

Max. inclination exceeded

Engine temperature too high

Oil viscosity unsuitable (viscosity too
low)

Oil in oil pan too thin (mixed with con-
densation or fuel)

Heavy bearing wear

Oil pump gears heavily worn

Safety valve in oil circuit defective (does
not shut, spring fatigued or broken)

Oil pressure gauge defective

Dipstick marked correctly?
See Operator’s Manual

See ”Fuels, Lubricants ...”

Lub oil pressure too
high

Engine cold

Oil viscosity unsuitable (viscosity too
high)

Safety valve in oil circuit defective (does
not open)

Oil pipes/oil galleries clogged

Oil pressure gauge defective

See ”Fuels, Lubricants ...”

Lube oil consumption
too high

Leaks in the lube oil circuit, particularly
at the turbocharger and oil cooler

Oil level in oil pan too high

Lube oil quality does not satisfy regula-
tions

Turbocharger wear

Piston rings heavily worn

Valve guides heavily worn

See ”Fuels, Lubricants ...”

Measure play of rotor
