Steps to Torque the Head Bolts
To ensure the proper torque of the head bolts on your 1997 Honda CRV, follow these steps:
1. Begin by cleaning the threads of the head bolts and the bolt holes in the engine block using a suitable cleaning agent.
2. Apply a small amount of engine oil to the threads of each head bolt.
3. Insert the head bolts into their respective holes, ensuring they are properly aligned.
4. Gradually tighten the head bolts in the specified sequence using a torque wrench. Start with the lower torque value and gradually increase to the final torque value.
5. Repeat the tightening sequence, gradually increasing the torque to the final specified value.
6. Double-check the torque on each head bolt to ensure it meets the recommended specifications.
7. Once all the head bolts are properly torqued, you can proceed with the remaining steps of the engine assembly or maintenance.
Remember, it is crucial to follow the specified torque values and tightening sequence to prevent damage to the engine and ensure a secure and leak-free seal.
