5.5 Coolant level
5.5.1 Coolant level check
Check the levels of the coolant in the radiator cooler. The levels
show in transparent tubes fitted at the radiator top tank. The levels
should normally be at the bottom of the filler pipes as they go into
the tanks.
Add coolant, if necessary. The location of the radiator filler cap (1)
is shown in figure above.
Consult the Engine Operation Manual for the coolant solutions to
be used.
5.5.2 Test coolant inhibitor level
Use a refractometer and a pH-meter to test the ethylene glycol (EG)
coolant water. Freeze/boilover protection is determined by glycol
concentration.
5.5.3 Coolant change
Consult the Engine Operation Manual and section 5.5.2 for coolant
specifications.
To drain coolant from system, remove drain plugs. Drain plugs are
located at the right- and left-hand side under the unit and open the
drain cocks (1).
Use a proper drain pan.
Before filling the system, close the drain cocks and tighten all
plugs.
