Head bolt torque spec gm 3.1?

The head bolt torque specification for a GM 3.1L engine isn't a single number. It depends on the year and specific application of the engine, as well as whether you're using new head bolts or reusing them. You absolutely must consult a repair manual specific to your vehicle's year and model.

Using the wrong torque specification can lead to severely damaged engine components, including a blown head gasket. Don't rely on generic answers found online.

To find the correct torque specification:

* Find your vehicle's repair manual: This is the most reliable source. You can usually find these online (some are free, some are paid) or at auto parts stores.

* Use a reliable online database: Some websites (like those of professional repair information providers) have searchable databases of torque specs, but you'll still need to enter the precise year, make, model, and engine code of your vehicle.

Attempting this repair without the correct information is extremely risky. If you are not comfortable with this procedure, take your vehicle to a qualified mechanic.
