⚡ Tightening Torques & Specifications
| Component | Specified Torque | Assembly Notes |
|---|---|---|
| crankshaft main bearing cap bolts | Angle tightening in 3 stages: 50 Nm + 45 degrees + 15 degrees. value_nm null because it is an angle torque procedure | |
| oil pickup tube bolts | 22 N·m | 8 mm = bolt head size. Paulo explicitly sets the torque wrench to 22 N.m |
| oil pan M6 bolts (GM manual reference) | 20 N·m | WARNING: Paulo DOES NOT apply this value. Risk of snapping the M6 bolts. Recorded as reference from GM service manual |
| oil pan M6 bolts (value applied by Paulo) | 10 N·m | Paulo uses red Abro Lock and tightens in 3 sub-stages (under 5 Nm, 5 Nm, 10 Nm) due to the limitation of the M6 bolts |
| side engine mount bolt | 61 N·m | 6.2 kgf.m x 9.81 = 60.8 N.m approx 61 N.m |
