Removal and installation of the electromagnetic valve
1. Remove the coolant pump.
2. Disconnect a socket from the electromagnetic valve of system of change of phases of gas distribution.
3. Remove the bolts (751) mounting valve (752), remove it. Tightening torque 12 Nm.
4. Remove and discard gasket (753).
5. Installation is carried out in the reverse order.
Removal and installation of the valve
1. Remove the electromagnetic valve of system of change of phases of gas distribution.
2. Remove the system valve.
3. Install the variable valve timing system. Tighten the valve. Tightening torque: 1st pass by hand; 2nd pass 65 Nm; Tighten the 3rd pass by 90°.
4. Install the solenoid valve for variable valve timing.
Clutch drive system variable valve timing
Withdrawal
1. Remove the oil pump.
2. Remove valve (234) variable valve timing systems.
Caution: When removing and installing the drive clutch, do not apply axial force to the timing ring of the camshaft position sensor. The timing ring is attached to the clutch of the variable valve timing system with three fingers, so the application of axial forces can lead to ring displacement and ring spinning by the actuator return spring, followed by injury.
3. Remove the bolt and remove the drive clutch and timing chain from the camshaft nose. Place your fingers under the drive clutch sprocket and pull the drive off.
Removing the drive clutch of the variable valve timing system
4. Remove drive (235) and chain (208).
5. With a plastic clamp or wire, secure the camshaft position sensor timing ring to the clutch of the variable valve timing system drive.
Installation
1. Compress the chain tensioner and secure it with a suitable pin.
Attention:
- Correctly orient the clutch of the variable valve timing system relative to the locating pin.
- The sprocket teeth and chain links must engage.
- Align the timing marks on the camshaft and crankshaft sprocket.
- NEVER install a remounted variable valve timing actuator clutch solenoid valve.
2. Determine the relative position of the mounting hole (1) on the camshaft drive sprocket and dowel pin (2).
3. Install the drive clutch with the chain on the toe of the camshaft along the locating pin. If it is necessary to align the marks on the camshaft and crankshaft sprockets, slightly tighten one or both shafts in the desired direction. Push the drive onto the shaft by the sprocket, never push the drive clutch by the timing ring.

Caution: When removing and installing the drive clutch, do not apply axial force to the timing ring of the camshaft position sensor. The timing ring is attached to the drive clutch with three fingers, so the application of axial forces can lead to ring displacement and ring spinning by the drive return spring, causing injury.
4. Attach the ruler to the front surface of the cylinder block and check the correct installation of the drive and chain: when properly installed, the chain should not protrude beyond the plane of the front surface of the block.
5. Install the variable valve timing system. Tighten the valve by hand.
6. Check alignment of alignment marks (1) And (2). The mark on the camshaft sprocket must be in position "6 hours", on the crankshaft sprocket - in position "12 hours".
7. Remove the chain tensioner guide fixing pin.
8. Tighten the camshaft control valve. Tightening torque: 1st pass 65 Nm; Tighten the 2nd pass by 90°.
9. Install the oil pump.
