Diesel Engine Coolant - Kohler KD83V16 Operation And Maintenance Manual

Operation and Maintenance Manual
From the indicated test methods and limit values, it emerges when the result of a single oil sample
analysis is to be viewed as abnormal.
Kohler Co. recommends to perform lube oil analysis of used engine lube oil for the following
parameters (minimum list).
– Viscosity
– Flashpoint
– Soot
– TBN
– Water
– Oxidation
– Ethylene glycol
– Wear elements (Iron, Chromium, Tin, Aluminium, Nickel, Copper, Lead and Molybdenum)
– Contaminants (Silicon, Potassium, Sodium, Lithium, Antimony, Silver, Titanium, Vanadium,
etc...)
– Additives (Calcium, Magnesium, Boron, Zinc, Phosphorus, Barium, Sulfur)
– Diesel fuel rate (dilution)
Engine oil analysis
Analyze oil at regular intervals.
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 generator set 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.
