Inspection and servicing

Change cooling liquid

Read and observe: Inspection and servicing – Safety instructions.

Risk of scalding from hot cooling liquid.The radiators may also be hot. Wear protective gloves and firm working clothing.

Collect escaping cooling liquid and discard without polluting the environment.

The cooling liquid must be changed regularly and after 6000 OH at the latest.

Testing the cooling liquid composition

The „Engine operating instructions“ contain a detailed description of how to prepare and test the cooling liquid composition. In case of imminent frost check that the factory-adjusted anti-freeze concentration is sufficient for the expected temperatures.

Check the cooling liquid in the cooling system regularly to ensure that the SCA mixture is sufficiently concentrated to prevent corrosion under the corresponding operating conditions.

Fig. 3-19:

To do so:

" Prepare a collecting recipient for used cooling liquid. Choose the required recipient capacity in accordance with the "Refilling quantitiesOther" table.

" Shut off the engine.

" Open hatch 2 (Fig. 3-19:).

" Unscrew plug (arrow, Fig. 3-20:) and drain off cooling liquid completely.

" Re-insert the plug with a new sealing ring.

" Fill in special prepared cooling liquid CAT ELC, Terex|O&K Part No. 2482777 (see: "Refilling quantities - Other" table.)

Checking the SCA concentration

Observe the instructions of the engine manufacturer with regard to the SCA concentration (see engine manufacturer's operating instructions).
