Lubricants and operating fluids
Information
Average change intervals (to be validated by coolant analysis):
With Glysantin G48 = 6000 h or 4 years.
With Glysantin G40 = 8000 h or 6 years.
Corrosion inhibiting antifreeze (ready mixed or concentrated)
Corrosion-inhibiting antifreeze products approved by Kohler Co. guarantee adequate protection
against low temperatures, corrosion and cavitation, do not attack seals and hoses and are non-
foaming.
Coolant can be independently blended with the products listed in section "Water" and "anti-freeze
and corrosion protection agent" or as a made up blend.
Kohler Co. recommends to use ready mixed coolant.
Ready mixed coolant limits the risk for the operator while preparing the final coolant by mixing
concentrate coolant and water.
Corrosion inhibitor antifreeze ratio and water quality are determinant factors Coolants containing
unsuitable corrosion-inhibiting antifreeze products or which have not been prepared properly can
cause the failure of components and parts in the coolant circuit as a result of cavitation or corrosion
damage.
In addition, deposits with thermal insulation properties can build up on components that conduct
heat, leading to overheating and ultimately to failure of the engine.
The cooling system only operates reliably under pressure. Keep the cooling system clean and
sealed.
The cooling sealing and operating valves must function correctly. Maintain the required coolant
level.
Corrosion inhibitors
NOTICE
Corrosion inhibitors has to insufficient cavitation protection and lower boiling point limit.
Property damages by cavitation, corrosion or overheating.
u Corrosion inhibitors are forbidden on KOHLER engines.
Fresh water requirements
NOTICE
Using inadequate water could alterate the coolant properties and deposit impurities in the cooling
circuit.
Property damages by cavitation, corrosion or overheating.
u Use recommended water. Drain and flush cooling system if required.
NOTICE
Refilling with inadequate water or coolant mix could lead to precipitation of antifreeze product and
impurities in the cooling circuit.
Property damages by contamination or overheating.
u Use recommended water or coolant mix.
u By precipitation, replace the cooling circuit.
