OIL IN COOLANT OR COOLANT IN OIL.
Step 1.
Check for water in engine oil (1).
If engine oil appears a milky color, notify Direct Support maintenance (Appendix L).
Collect and submit an AOAP sample of engine oil, and wait for further direction from AOAP lab.
If vehicle has been operating, use extreme care to avoid being burned when removing radiator cap or
coolant reservoir cap. Sudden release of pressure can cause a steam flash which could seriously
injure personnel. Use heavy rags to protect hands. Slowly loosen cap to the first stop and allow
pressure to be relieved before removing cap completely. After use, securely tighten cap. Failure to
comply may result in injury or death to personnel.
Step 2.
Check coolant (2) for contamination.
If contaminated, notify Direct Support maintenance (Appendix L).
