Step-by-Step Guide to Torque the Head Bolts
To ensure the head bolts are torqued correctly on your 2011 Chevy 5.3 engine, follow these steps:
1. Start by cleaning the threads of the head bolts and the bolt holes in the engine block using a suitable cleaning solution.
2. Apply a small amount of engine oil to the threads of each head bolt.
3. Begin the torque sequence by tightening all head bolts to 22 ft. lbs. (30 Nm) in the numerical order specified by the manufacturer.
4. Once all head bolts have been torqued to the initial specification, go back and tighten them an additional 90 degrees in the same numerical order.
5. Repeat the 90-degree tightening process two more times, for a total of three rounds of 90-degree turns.
6. After the final 90-degree turn, the head bolts should be properly torqued and secure.
It is crucial to follow the specified torque sequence and values to ensure proper sealing and prevent any issues with the engine’s performance or integrity.
