What are the head bolts torqued to on a c12 cat?

On a Cat C12 engine, the cylinder head bolts are typically torqued to a specification of around 60-65 ft-lbs (81-88 Nm) for the initial pass, followed by an additional angle of rotation, often around 90 degrees, depending on the specific service manual instructions. It's crucial to follow the manufacturer's guidelines for the proper torque sequence and specifications to ensure a correct and reliable assembly. Always refer to the latest service manual for accurate torque settings, as they may vary slightly based on engine configuration or updates.
