Torque Values
Engine
Component | Torque Value | Installation Notes | Removal Notes |
---|---|---|---|
Camshaft sprocket bolt | 88Nm | Securely restrain the cam sprocket using a cam sprocket holding tool, and use a big breaker bar or high torque impact gun. | |
Camshaft Front and Rear cap bolts (12mm) | 20Nm | Must be tightened in sequence as per workshop manual | Camshaft bolts must be removed in sequence to avoid damaging the camshaft |
Camshaft front cap bolt (10mm) | 10-12Nm | One end of the camshaft has three bolts. The smaller bolt uses this torque value. | Camshaft bolts must be removed in sequence to avoid damaging the camshaft |
Camshaft cap bolts | 10-12Nm | Camshaft bolts must be removed in sequence to avoid damaging the camshaft | |
Oil Pan bolts | 7Nm | ||
Flywheel inspection/Flex plate inspection bolts | 44Nm | ||
Turbo oil return bolts (to block) | 9Nm | ||
Oil Drain bolt | 39Nm | Replaced sealing washer each time | |
Harmonic balancer (crankshaft pulley) | 177-186Nm | Lock the engine either by restraining the pulley or using a screwdriver to hold the ring gear on the flywheel | May require extreme torque impact gun (1500Nm+). Alternatively use breaker bar and extension wedged against the ground, and engage the starter motor (disconnect the Crank Angle Sensor first so the engine does not start!!) |
Rocker cover bolts | 3.5Nm | Do not overtighten. Rely on the rocker cover gasket to do its job. | |
Flywheel bolts
Flex plate bolts |
93-103Nm | Can use blue loctite for assurance | Hold the flywheel in place with a screwdriver lodged in the ring gear teeth, or use a high torque impact gun. The bolts have low profile heads - ensure your socket or impact gun is securely gripping each bolt before removal. |
Timing Belt tensioner bolts | 22Nm | ||
Timing Belt tensioner pulley bolt | 48Nm | Recommend replacing this bolt with higher tensile to reduce risk of tensioner pulley bolt shearing and catastrophic engine damage (e.g. valve to piston contact) | |
Timing belt tension | 3Nm | Accurate measurement requires special tool MD998767 and a Beam style torque wrench |
