To find the correct torque specification:
1. Locate your owner's manual: This is the most reliable source.
2. Look for the maintenance section: It will contain specifications for oil changes, including the drain plug torque.
3. Alternatively, use a reliable online resource: Sites like GM's official website or a reputable repair manual database (like AllDataDIY or Mitchell 1) might have the information if you can provide the exact year, make, and model of your vehicle.
Attempting to tighten the drain plug without the correct torque specification risks stripping the threads or over-tightening, causing damage to the engine block. Always consult your owner's manual for the correct procedure and specifications.
