New Cooling System Cleaner Now Available For All Engines{1350,0680,1352,1353}

Usage:

Reference: "Coolant And Your Engine," SEBD0970, "Know Your Cooling System," SEBD0518.

Another cooling system cleaner is now available from the Caterpillar Service Technology Group which will allow one-step cleaning and new coolant refill. This new cleaner can be used for preventive maintenance (similar to the present 6V4511 Cleaner) but is used as a short-time flush at the time of coolant change. Both of these cleaners are available.

The new cleaner is available from the Parts System in the following container sizes:

4C4609: 0.236 L (1 pint)

4C4610: 1.98 L (1 quart)

4C4611: 3.78 L (1 gallon)

4C4612: 18.9 L (5 gallon)

4C4613: 208 L (55 gallon) drum

This mild solvent will not be effective in cooling systems that have been neglected or have heavy scale build-up. A stronger commercial solvent is required to clean these cooling systems.
