Steps to Torque the Head Bolts
To properly torque the head bolts on your B18B1 engine, follow these steps:
1. Start by ensuring the cylinder head and engine block surfaces are clean and free of debris or old gasket material.
2. Apply a thin layer of engine oil to the threads and washer surfaces of each head bolt.
3. Begin by tightening all head bolts to 22 ft. lbs. (30 Nm) using a torque wrench in the specified sequence.
4. Repeat the tightening process, increasing the torque to the final specification of 25 ft. lbs. (34 Nm) in the same sequence.
5. Double-check each bolt to ensure it is torqued correctly.
6. Finally, perform a final pass, increasing the torque by an additional 90 degrees (1/4 turn) for each bolt in the specified sequence.
Following these torque specifications and steps will help ensure proper clamping force and prevent any potential leaks or engine damage.
Remember to always consult the manufacturer’s service manual or a trusted source for the most accurate and up-to-date torque specifications for your specific engine model.
