Removal
1. Loosen the intake manifold mounting bolts and nuts and remove the manifold and its gasket.
2. Remove the exhaust manifold mounting nuts and washers, remove the manifold and its gasket.
3. Use a special key (09221— 32000), unscrew the cylinder head mounting bolts in the order shown in the figure.
4. Remove the cylinder head and gasket from the cylinder block.
Examination
1. Remove scale, sealing material and carbon deposits. After cleaning the oil passages, blow them out with compressed air.
2. Visually inspect the cylinder head for cracks, damage and coolant leaks.
3. Check the bottom surface of the head for flatness using a ruler with a sharp edge, as shown in the figure.
Deviation from flatness:
- Nominal value - less than 0.05 mm
- Limit value - 0.2 mm
Intake and exhaust manifolds
1. Visually inspect the collectors for cracks and damage.
2. Check the EGR passage and the intake manifold coolant passage for contamination and clean them if necessary.
Installation
1. Clean the bottom surface of the cylinder head and the top surface of the block itself.
2. Check the identification marks on the head gasket.
3. The surface of the gasket with the identification mark must face the cylinder head.
Note: To improve sealing effectiveness, apply sealant to the cylinder head gasket around the four oil drain holes.
4. Install the cylinder head bolts.
5. Using a special key (09221— 32001), starting with the center bolts, tighten all head mounting bolts to 1/2 the required torque in the sequence shown in the illustration.
6. Tighten all cylinder head bolts in the same sequence to the specified torque.
- Tightening torque: Cylinder head bolts Cold engine (engine coolant temperature about 20°C) — 105-115 Nm.
7. Clean the mating surfaces of the intake and exhaust manifolds and the cylinder head.
8. Install new exhaust and intake manifold gaskets.
9. Install the intake and exhaust manifolds and tighten the bolts and nuts to the specified torque.

- Tightening torque: Bolts and nuts of the intake and exhaust manifolds - 15-20 Nm.
