Coolant Conditioner Elements
At operating temperature, the engine coolant is hot and under pressure.Steam can cause personal injury.Check the coolant level ONLY when the engine is stopped and the radiator fill cap is cool enough to touch with your hand.Remove the fill cap slowly to relieve pressure.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.
All water is corrosive at engine operating temperature. Use Caterpillar Coolant Conditioner Elements to treat either plain water or ethylene glycol solution.Do not use Caterpillar Coolant Conditioner Elements if Dowtherm 209 Full-Fill Coolant is used. Follow the recommendations with the Dowtherm 209 Full-Fill Coolant.
Use a Caterpillar Part Number 1W5518 precharge element when the cooling system is drained and refilled. This will establish the proper initial conditioner concentration.Use a Caterpillar Part Number 9N6123 maintenance element every 250 service hours thereafter, to maintain the proper conditioner concentration.If the coolant conditioner elements have been regularly changed at 250 service hours, the change period for engine coolant can be extended to 4000 hours.Refer to the "Maintenance" (Lubrication and Maintenance) Guide for the procedures to change the antifreeze solution, or flush the cooling system.To Change Element
1. Remove the radiator cap slowly to relieve pressure in the cooling system. 2. Close the inlet valve and the outlet valve at the element base. Turn each handle clockwise to close each valve. 3. Remove the coolant conditioner element. Discard the element. 4. Clean the element mounting base. Make certain all of the old element gasket material is removed.5. Use the correct precharge or maintenance element for your cooling system. Elements are sized according to the cooling system capacity. 6. Coat the seal of the element with a thin film of clean engine oil or antifreeze. 7. Install the element. Tighten it until the seal contacts the base, then tighten it an additional 3/4 turn. 8. Open the inlet valve and the outlet valve. 9. Maintain the coolant level above the low level plate.10. Clean and install the radiator cap.11. Start the engine and check for leaks.Fuel Specifications for Direct Injection Engines
Caterpillar Diesel Engines have the ability to burn a wide variety of fuels. These fuels are divided into two general groups, preferred and permissible.Types of Fuel
The preferred fuels provide maximum engine service life and performance. They are distillate fuels. They are commonly called fuel oil, furnace oil, diesel fuel, gas oil, or kerosene.The permissible fuels are crude oils or blended fuels. Use of these fuels can result in higher maintenance costs and reduced engine service life.See Caterpillar Form Number SEHS7067, "Fuels for Caterpillar Diesel Engines," for a detailed summary of preferred and permissible fuels and their specifications.Cetane Requirement
The minimum cetane number recommended for the engine is 40.Fuel Cloud Point
Fuel waxing can plug the fuel filters in cold weather. The fuel cloud point must be below the temperature of the surrounding air to prevent filter waxing and power loss. Fuel heating attachments are available from your Caterpillar dealer to minimize fuel filter waxing.Fuel Sulfur Content
