Coolant Conditioner Element
At Operating Temperature, engine coolant is hot and under pressure.Steam can cause personal injury.Check coolant level ONLY, when engine is stopped and radiator cap is cool enough to touch with your hand.Remove filler cap slowly to relieve pressure.Cooling System Inhibitor contains alkali. Avoid contact with skin and eyes to prevent personal injury.
All water is corrosive at engine operating temperature. Use either Caterpillar Cooling System Inhibitor liquid, or the coolant conditioner element to treat either plain water or ethylene glycol solution.Do not add both the liquid cooling system inhibitor and the coolant conditioner element at the same time.
When changing antifreeze solution, replace the maintenance filter element with the correct precharge element.
The normal coolant conditioner element must not be used with Dowtherm 209 coolant.
Excessive coolant conditioner (greater than the recommended 6% initial fill) together with concentrations of antifreeze greater than 65% cause deposits to form and may result in radiator tube blockage and overheating.
When fresh engine coolant consisting of either plain water or water and antifreeze is installed, a precharge element should be installed for use until the first normal element change period. 1. Close inlet valve and outlet valve at element base. Turn clockwise to close both valves. 2. Remove the coolant conditioner element. Discard element.3. Clean element mounting base. Make certain all of old element gasket material is removed.4. Use the correct maintenance element for your cooling system. Maintenance elements are sized to the coolant system capacity. 5. Coat the seal of the element with a thin film of clean engine oil or antifreeze. 6. Install the element until seal contacts base, then tighten an additional 3/4 turn. 7. Open the inlet valve and outlet valve.8. Start engine and check for leaks.Coolant Level
Check the engine coolant daily with the engine stopped and cool.1. Slowly turn the filler cap to the first stop to release pressure.
Be careful: If the engine is warm-steam may spray outward under high pressure.
2. Push the cap down and turn until the cap is released. 3. Maintain coolant level to the base of the fill pipe. 4. Make-up coolant should be with water free as possible from scale forming minerals (not softened water) and a permanent type antifreeze containing rust inhibitor or a solution of water and Caterpillar Corrosion Inhibitor. Follow the recommendations given on the container.Maintain a 3% concentration of Caterpillar Corrosion Inhibitor.
Do not use with Dowtherm 209.
Make-up water added without the proper proportions of coolant corrosion inhibitor can cause excessive lime deposits and corrosion.
Add coolant slowly to a hot engine to prevent possible cracking or distorting the cylinder head.
If a loss of coolant is noticeable, check for leaks in the system. After filling the system, start the engine and recheck the coolant level after normal operating temperature is reached. Running the engine at operating temperature will permit the temperature regulator to open and allow the coolant to circulate through the entire system and purge air from the engine.If a permanent antifreeze solution is used in the cooling system, either renew the
