your fuel supplier should treat the fuel when additives are needed.Cooling System
Note: Refer to Special Publication , SEBU6251, "Cat Commercial Diesel Engine Fluids Recommendations" for complete information about the proper fluids for use in the cooling system.
The cooling system operates under pressure which is controlled by the radiator pressure cap. Removing the cap while the system is hot may allow the escape of hot coolant and steam, causing serious burns.Before you remove the radiator cap, allow the system to cool. Use a thick cloth and turn the radiator cap slowly to the first stop to allow pressure to escape before fully removing the cap.Avoid contact with coolant.
Never add coolant to an overheated engine. Engine damage could result. Allow the engine to cool first.
If the engine is to be stored in, or shipped to an area with below freezing temperatures, the cooling system must be either protected to the lowest outside temperature or drained completely in order to prevent damage caused by freezing coolant.
Never operate an engine without water temperature regulators in the cooling system. Water temperature regulators help to maintain the engine coolant at the proper operating temperature. Cooling system problems can develop without water temperature regulators. Removing the regulators allows some coolant to bypass the radiator, potentially causing overheating.Coolant Recommendations

Min requirements for Commercial coolants requiring SCA precharge "ASTM D4985" and(1)
Nitrite (as NO2) concentration: Minimum of 1200 ppm (70 grains/US gal) and maximum of 2400 ppm (140 grains/US gal)
Silicon concentration: minimum of 100 ppm and maximum of 275 ppm 3000 hours or 1 year SCA at initial fill and SCA at maintenance intervals
(1) New Coolants at 50 volume percent diluted. Coolants that are prediluted at the coolant manufacturer must be diluted with water that meets Reagent 4 "ASTM D1193" requirements.
(2) Maintain the in-service coolant at the given limits.
(3) When referring to the service hours, use the interval that occurs first. These coolant change intervals
