5. Begin torquing the head bolts in a specific sequence. For the 2.4L inline-four engine, start with bolt number 1 and tighten it to 22 ft. lbs. (30 Nm). Then, tighten bolts 2, 3, 4, and 5 to 22 ft. lbs. (30 Nm) in sequence. Finally, tighten all bolts to 29 ft. lbs. (39 Nm) in sequence.
6. For the 3.0L V6 engine, start with bolt number 1 and tighten it to 22 ft. lbs. (30 Nm). Then, tighten bolts 2, 3, 4, 5, 6, and 7 to 22 ft. lbs. (30 Nm) in sequence. Finally, tighten all bolts to 29 ft. lbs. (39 Nm) in sequence.
7. After torquing all the head bolts, repeat the sequence and torque them again to the specified values.
8. Reinstall any components that were removed and ensure they are properly secured.
9. Double-check all connections and make sure everything is in place before starting the engine.
Following these torque specifications and steps will help ensure the proper assembly and sealing of the cylinder head on your 2003 Honda Accord. It is important to use a torque wrench and follow the specified sequence to avoid any damage to the engine components.
Remember, proper torqueing of the head bolts is essential for the overall performance and reliability of your Honda Accord’s engine. By following the manufacturer’s recommendations, you can maintain the longevity and efficiency of your vehicle.
