Tighten bolts (19). Use any tightening sequence.Torque for bolts ... 47 7 N m (34 5 lb ft)If equipped, use the following procedure in order to tighten the bracket for the fuel pump and the bracket for the timing cover to the cylinder heads:Note: The first four bolts (either cylinder head) toward the front of the engine are used in order to secure the brackets for the timing cover and the fuel pump to the engine.
Position the mounting brackets over the bolt holes that are in the cylinder head. Install the cylinder head bolts through the bracket. Finger tighten the bolts.
Align the fuel pump or the timing cover against the mounting brackets and install the mounting bolts. Finger tighten the bolts.
