CYLINDER HEAD BOLT TORQUE/SEQUENCE
Note: Apply a coat of engine oil to washers and bolt threads.
1. Tighten all bolts to 29 N.m (3.0 kg-m, 22 ft-lb) in numerical order.
2. Then tighten all bolts to 69 N.m (7.0 kg-m, 51 ft-lb) in numerical order.
3. Back off all bolts by 180° first; back them off by 180° again.
4. Tighten bolts (1) and (2) to 34 N.m (3.5 kg-m, 25 ft-lb).
5. Tighten bolts (3), (4), (5) and (6) to 15 N.m (1.5 kg-m, 11 ft-lb).
6. Tighten all bolts by 80° to 90° in numerical sequence.
CAUTION: Do not tighten bolts more than 90°.
7. Further tighten all bolts by 80° to 90° in numerical sequence.
CAUTION: Ensure that the total "re-tightening angle" does not exceed 180°.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
