2.6 Coolant
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
2.5.5 Emission-Related Installation Instructions
Failing to follow the instructions in the applications guidebook when installing a certified engine in a piece of nonroad equipment
violates federal law (40 CFR 1068.105(b)), subject to fines or other penalties as described in the Clean Air Act.
OEM must apply a separate label with the following statement: “ULTRA LOW SULFUR FUEL ONLY” near the fuel inlet.
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.
