- Align the compressor housing with the exhaust manifold in order to get all four nuts started. Tighten all four nuts snugly.
Note: Because of interference, assemble the fasteners according to Illustration 2.
- Tighten one bolt to 54 ± 5 N·m (40 ± 4 lb ft).
- Tighten the diagonal bolt to 54 ± 5 N·m (40 ± 4 lb ft).
- Tighten the remaining two bolts to 54 ± 5 N·m (40 ± 4 lb ft).
- Repeat the tightening sequence with all four bolts in order to verify that the torque is 54 ± 5 N·m (40 ± 4 lb ft).
