The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
When removing or installing the engine oil drain plug, the heli-coil may come out of position. In some instances it may come out with the drain plug. This is the result of an issue with the original heli-coil, not the oil pan.
Recommendation/Instructions:
If this concern is encountered, remove the oil heli-coil and install a new one using a M12 x 1.75 heli-coil from a local supplier. The instructions from the heli-coil supplier should be used. If necessary, several heli-coil suppliers can be located on
the internet by entering "heli-coil" in the internet browser and clicking search.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
