Removal Procedure
Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads
must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury
and/or damage to the vehicle or its components.

- Apply one drop of thread lock compound GM P/N 12345382 or equivalent to the cleaned oil pan bolt threads.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
Important: Do not overtighten bolts or damage to the oil pan may occur, resulting in an oil leak.
