Water specification

When the user wants to blend their own mixture, Kohler recommends the use of fully deionized

water. If the user wants to use tap water, this water must fulfill the requirements for drinking

water according to 2006 WHO (World Health Organization) guideline.

Tab. 38: KD water requirements

Information
The use of sea water, brackish water, salt water, and industrial waste water is prohibited.

Coolant concentration

Kohler recommends a concentration of antifreeze and corrosion-protection agents of 40% all

year round in power supply applications.
Only coolants with a glycol content lower than 55% are allowed in Kohler KD diesel engines.

Higher concentrations prevent proper heat transfer and are thus forbidden. Should your appli‐

cation need additional antifreeze protection (arctic conditions), please contact your Kohler Co.

representative for additional information.

Coolant monitoring

Kohler recommends a close monitoring of the coolant to prevent diesel engine damage by cavi‐

tation, corrosion, overheating, or freezing. Monitoring of the coolant can extend the exchange

period of the fluid for up to 6 years for SI and SIOAT-based coolants. It can extend the exchange

period of the fluid for up to 4 years for hybrid technology coolants.
Kohler recommends the following list of parameters to be checked by coolant analysis at least

once a year. However, the user should always check with their coolant provider what the

recommendations for analysis and monitoring of their coolant are, according to engine oper‐

ating conditions.

Information
Topping up the cooling system with inadequate water or non-compatible coolant mixtures can

lead to precipitation in the fluid and malfunction of the engine.
