CAMSHAFT 1879381 - Caterpillar

All EnginesCaterpillar now makes the recommendation that Caterpillar Cooling System Inhibitor be used either with or without an ethylene glycol based antifreeze in the coolant. It is important that this inhibitor be used all through the year to prevent corrosion, cavitation and erosion in the cooling system. Since this is a change from former recommendations, the instructions on the inhibitor container are wrong. Corrections are being made to the container instructions, but the new containers will not be available for some time. The new container will have the information that follows:
Caterpillar Cooling System Inhibitor
... Prevents rust and scale deposits.
... Permits a reduction in cavitation, erosion and corrosion.
... Keeps the cooling system clean.
... Gives protection to most metals.
Do not use in engines with aluminum cylinder head and block.
... Does not damage gaskets or hoses.
... Can be used with glycol base antifreeze.
Do not use with Dowtherm 209.
... Has no negative effects on oil.
Instructions For Use
For best protection against cavitation, erosion, and corrosion, use inhibitor as shown in the chart.
Before first addition of inhibitor to the coolant, the cooling system must be flushed and cleaned with chemicals if necessary.
Contains alkali. Avoid contact with eyes. Avoid prolonged or repeated contact with skin. Do not take internally. In case of contact, immediately wash skin with soap and water. For eyes, flush with large amounts of water for at least 15 minutes. Call physician. Keep out of reach of children.
Make sure your customers know about this change in the recommendations for use of Caterpillar Cooling System Inhibitor.
