Coolant samples should be obtained from the
coolant sample port. You should not obtain the
samples from the drain valve or from the filler tube.
2. The filter element can be cleaned by using
pressure air. Use a maximum air pressure of
205 kPa (30 psi). Direct the air from the clean
side to the dirty side.
For additional information about sampling
the coolant, see Operation and Maintenance
Manual, SEBU6250, “Caterpillar Machine Fluids
Recommendations” or consult your Caterpillar
dealer.
3. Look through the filter toward a bright light.
Inspect the element for damage. Inspect the
gaskets for damage. Replace damaged filters.
Perform a Coolant Analysis (Level 1) at 250
hours for systems that contain diesel engine
antifreeze/coolant (DEAC).
4. Install the filter element.
Level 1 results may indicate a need for Level 2
Analysis.
Note: Clean the filters more often in dusty conditions.
