Note: When installing, fasten all thermal insulation sleeves in their original positions.
Remove the camshaft housing. Remove intake manifold. Disconnect electrical connectors.

2. Charge pressure regulator -V465-
Unscrew screw -1- of engine support bracket.
Loosen the cylinder head bolts in sequence and unscrew. Remove the MCC and place it on a soft pad (foam or similar material).
Installation
Carefully! Risk of damage to mating surfaces. When repairing, carefully remove sealant residues from the cylinder head and cylinder block. At the same time, do not leave furrows and scratches. Risk of damage to the cylinder block. Do not allow oil or coolant to enter the threaded holes of the cylinder block (for cylinder head bolts). Danger of insufficient sealing of the cylinder head. Carefully remove the remains of abrasive and polishing materials. Remove the new cylinder head gasket from the packaging immediately before installation. The gasket should be handled carefully, trying not to damage the silicone layer and the rolling of the edges of the gasket. Replace the screws that are tightened with additional turning to the specified angle. Replace self-locking nuts as well as lip seals, O-rings and gaskets. When installing a cylinder head from an exchange fund, it is necessary to lubricate the friction surfaces of the hydraulic lifters, roller levers and camshaft cams with engine oil before installing the camshaft housing. Fix all hose connections with clamps corresponding to those installed at the factory. When replacing the cylinder head or its gasket, completely replace the coolant and oil in the engine.
Install cylinder head gasket -1-. Check for presence of dowel pins -arrows- in cylinder block. Install the cylinder head gasket, taking into account the marking: the part number must be read from the side of the intake valves.
If the crankshaft rotated during this time: set the piston of the 1st cylinder to the top dead center position. Again slightly turn the crankshaft back. Install cylinder head. Insert cylinder head bolts and tighten by hand. Tighten the cylinder head screws,
Note: It is not necessary to tighten the cylinder head bolts after the repair.
Installation in reverse order. Install the camshaft housing. Install intake manifold. Change engine oil. Replace coolant.
