The haynes book is not recommended since there are numerous mistakes and they still will not update. One of the biggest is the firing order.

The factory service manual is the only way to go.

Head bolts - 46 - 50.5 lbs (there is an order sequence for the bolts)

Intake & exhuast manifolds- 13.5 - 20 lbs

Flywheel - 41.5 - 47 lbs

Clutch cover - 13.5 - 20 lbs

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Here is a pic of the sequence

How is the camshaft timing set on a 1.4 turbo 2012 cruze


Hi Peter You will need to purchase a special timing kit to set up the timing. I would only advise an experienced mechanic to set it up. There is a pin which screws through the front of the engine and locks into a slot on the crankshaft. there is a flat bar which locks into the cut out at the rear of the camshaft and rests along the flat of the cylinder head. Also the camshaft front pully (variable timing gear). This has a phaser plate attached and this is set up with a third tool in the kit which is bolted to the cylinder head.
Replace bolt that runs through the gear into the camshaft and torque to specs Do not overtighten. Replace the cover cap to this bolt and tighten to specs. Both these parts need to be replaced. Oil flow is vital so sealing is a must the cap comes with a new seal Do not apply any other sealant in these areas. Good luck
