Omega Engineering 185-210 DUS Engine OIL and Filter, Engine Cooling Specifications, Mixtures

4.2 ENGINE OIL AND FILTER

See engine manufactures operator/instruction manual for the proper engine oil and filter changing intervals for the brand engine in your Boss compressor.

OIL FILTER REPLACEMENT

1.Clean the area around the lubricating filter head.

2.Remove the filter.

3.Clean the o-ring surface of the filter head.

NOTE: The o-ring can stick on the filter head. Make sure it is removed.

4.Apply a light film of lubricating oil to the o-ring-sealing surface before installing.

5.Install the filter as specified by the filter manufacturer.

CAUTION

MECHANICAL OVER-TIGHTENING MAY DISTORT THE THREADS OR DAMAGE THE FILTER ELEMENT SEAL.

4.3 ENGINE COOLING SPECIFICATIONS

Diesel engines require a balanced coolant mixture of water and ethylene glycol base antifreeze. This protects the engine cooling system from corrosions as well as freezing damage. The Boss compressor is shipped from the factory with a 50/50 mixture of water and ethylene glycol. In tropical climates where freeze protection is not required, glycol engine coolant should still be used. It will help prevent corrosion and pitting of cylinder liners. See engine manufactures operator/instruction manual for the proper engine coolant for the brand engine in your Boss compressor.

MIXTURES:

Antifreeze concentration level should not exceed recommended levels. Doing so can cause cooling system failure.

·Use a high quality, low silicate antifreeze

·A mixture of 50% antifreeze and 50% water is required for temperatures above –37 º C (-34 ºF).

·A mixture of 60% antifreeze and 40% water us required for environments below –37 ºC (-34 ºF). This provides protection to –54 ºC (-65 ºF).

·Never exceed a 60% antifreeze and 40% water mix.

ENGINE COOLING SYSTEM

All engines have a pressurized cooling system that contains a 50/50 mixture of water and ethylene glycol. Daily maintenance of the system includes a check of the coolant level, proper belt adjustment of fan and water pump drives, soundness of fan and cleanliness of the radiator and oil cooler to permit airflow. Further cooling system maintenance is defined in the engine maintenance manual.
