Which way does the crankshaft bolt on a buick 3.8 engine turn to come off?

The crankshaft bolt on a Buick 3.8 engine, like most engines, is left-hand threaded. This means you need to turn it counter-clockwise to loosen it and clockwise to tighten it.

This is the opposite of most other bolts and nuts on your car. This is done intentionally to prevent the bolt from loosening due to the engine's rotation.

However, it's crucial to confirm this information specifically for your engine year and model. Different manufacturers and engine variants may have different specifications. Always consult your service manual or a reliable source for accurate information about your specific Buick 3.8 engine.
