Procedure for Torquing Head Bolts
To ensure the correct tightening of the head bolts, follow these steps:
1. Clean the threads of the head bolts and the bolt holes in the engine block to remove any dirt or debris.
2. Apply a small amount of engine oil to the threads of each head bolt.
3. Begin by tightening all head bolts to 37 ft. lbs. (50 Nm) in a crisscross pattern.
4. Next, tighten each head bolt to 68 ft. lbs. (92 Nm) in the same crisscross pattern.
5. Finally, tighten each head bolt to the specified torque value according to the table above (95-105 ft. lbs. or 129-142 Nm), again using the crisscross pattern.
By following these torque specifications and tightening procedures, you can ensure the proper installation and sealing of the cylinder head on the C15 ACERT engine. This will help maintain the engine’s performance, reliability, and longevity.
