Notes on the cooling system
On water cooled engines the preparation and
monitoring of the coolant is of utmost importance,
as otherwise engine failures caused by corrosion,
caviation and freezing may occur.
The coolant is a mixture of water and a cooling
system protection agent.
The cooling system must be permanently moni-
tored. Apart from the coolant level inspection this
includes also the inspection of the concentration of
cooling system protection agent.
The concentration of the cooling system protection
agent can be checked with commercially available
test instruments (glycomat).
! Danger
Health hazard!
The mixing of nitride based cooling system
protection agents with amine based agents will
cause the generation of highly toxic nitro-
samines.
Environment
Cooling system protection agents must be dis-
posed of environmentally.
5.2 Fuels and lubricants
Engine oil
Quality
Lubrication oils are classified according to their
performance and quality class. Oils according to
other comparable specifications may be used.
The exact assignment of the approved oil qualities
and oil change intervals can be taken from the fol-
lowing section "Lubrication oil change intervals".
Consult your local service station if in doubt.
Oil viscosity
Multi-purpose oils should be generally used.
Since lubrication oil changes its viscosity with the
temperature, the ambient temperature at the oper-
ating location of the engine is of utmost impor-
tance when choosing the viscosity class (SAE-
class) .
Optimal operating conditions can be achieved by
using the opposite oil viscosity chart (Fig. 68) as a
reference.
Occasionally falling short of the temperature limits
will impair the cold starting ability, but will not
cause any engine damage. In order to keep the
occurring wear as low as possible, occassional ex-
ceeding of the limits should not happen over a
longer period of time.
