Coolant Recommendation; Battery Recommendation - Kohler KDI 2504TM Workshop Manual

Ensure you are installing an engine appropriately certified for your application. Constant speed engines
may only be installed on constant speed equipment for constant speed operation.
If you install the engine in a way that makes the engine's emission control information label hard to read
during normal engine maintenance, you must place a duplicate label on the equipment, as described in 40
CFR 1068.105.

2.6 Coolant recommendation

A mixture of 50% demineralized water and 50% low silicate ethylene glycol based coolant liquid must be
used. Use a Long Life or Extended Life Heavy Duty OAT coolant free of: silicates, phosphates, borates,
nitrites and amines.
The following ethylene-glycol based engine coolant for all models within KDI engine family may be used:
•
OAT (Organic Acid Technology) Low Silicate: ASTM D-3306 D-6210
•
HOAT (Hybrid Organic Acid Technology) Low Silicate: ASTM D-3306 D-6210
The above coolants in concentrated formulation must be mixed with distilled, deionized, or demineralized
water. A pre-mixed formulation (40-60% or 50-50%) can be used directly when available.
Important
•
Do not mix ethylene glycol and propylene glycol based coolants. Do not mix OAT and HOAT based
coolant. OAT performance life can be drastically reduced if contaminated with nitrite-containing
coolants.
•
Never use automotive-type coolants. These coolants do not contain the correct additives to protect
heavy – duty diesel engines.
OAT coolants are maintenance free up to 6 years or 6000hrs of operation, provided that the cooling system
is topped up using the same type of coolant. Do not mix different coolant types. Test the coolant condition
annually with coolant test strips.
HOAT are not all maintenance free and it is recommended to have SCA (Supplemental Coolant Additives)
added at the first maintenance interval.
