INTAKE MANIFOLD TORQUE AND SEQUENCE
Install intake manifold retaining bolts, and tighten in sequence from the middle bolts towards the outside in a crisscross pattern. Torque fasteners to 12 Nm (105 in. lbs.).
THROTTLE BODY TORQUE AND SEQUENCE
1. Install all throttle body mounting bolts finger tight.
CAUTION: The throttle body mounting bolts MUST be torqued to specifications. DO NOT OVER TIGHTEN MOUNTING BOLTS. Over tightening can cause damage to the throttle body, throttle plate, gaskets, bolts and/or the intake manifold. Proper torque of the mounting bolts is critical to normal operation.
2. Obtain a torque wrench. Tighten mounting bolts (as shown) in a mandatory torque criss-cross pattern sequence to 5.6 Nm (50 in. lbs.).

- • 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.
