Diesel Engine Coolant - Kohler KD62V12 Operation And Maintenance Manual

Operation and Maintenance Manual
The oil analysis makes it possible:
– to draw conclusions about the oil condition,
– to survey the progress of wear,
– to detect potential damage,
– to take preventative measures,
– to increase the application availability
– with the laboratory report, to optimize the oil change,
– to minimize the environmental pollution by reducing waste oil.
Only authorized specialist personnel must carry out the oil analyzes according to the inspection
and maintenance schedule.
If the operating hours value specified in the inspection and maintenance schedule is not achieved
within 2 years, carry out an oil analysis for the identified oil circuits after 2 years at most.

Coolant requirements
NOTICE
Mixing different anticorrosion antifreeze agents or prepare unproperly the coolant could alterate the
coolant properties.
Property damages by cavitation, corrosion or overheating.
u Do not combine different products. Drain cooling system if required.
u Do not mix silicate-based and non-silicate based coolants.
u Check the coolant and cooling system according to maintenance spreadsheet.
u Keep the cooling system clean and sealed.
Coolant is a mixture of water with corrosion-inhibiting antifreeze products as additives.
KOHLER engines are tested and approved with SI-OAT-Technology based on Ethylene glycol.
These products are based on BASF Glysantin G40 or G48 coolants.
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.
