You will need a torque wrench to get the job done.
Removing
1. We install the car on a viewing hole or overpass (see "Vehicle preparation for maintenance and repair").
2. For the convenience of work, remove the battery (see "Battery - removal and installation").
3. Drain the coolant (see "Coolant - level check and replacement").
4. Disconnect the wire tip from the coolant temperature indicator sensor (see "Coolant temperature gauge sensor - replacement").
5. We turn out the spark plugs from the cylinder head (see "Spark plugs - condition check and replacement").
6. Remove the exhaust pipe from the exhaust manifold studs (see "Downpipe - removal and installation").
7. Set the piston of the 4th cylinder to the BMT position of the compression stroke and remove the housing assembly with the camshaft, valve actuator levers and springs (see "Camshaft and valve levers - replacement").
8. We tie the chain with wire and pass it through the window in the cylinder head.
9. We unscrew the nut of the upper fastening of the heat shield of the starter (see "Starter - removal and installation")
10. Remove the tip from the exhaust manifold stud "mass" wires (see "Gasket of the inlet pipeline and an exhaust manifold of the injection engine - replacement").
11. Disconnect the wire blocks from the throttle position sensor (see "Throttle Position Sensor - Check and Replace") and coolant temperature sensor (see "Coolant temperature sensor - check and replace").
12. Disconnect the block of wires from the idle speed controller (see "Idling regulator - check, removal and installation") and the block of the wiring harness for the injectors from the engine harness (see "Fuel rail - removal, installation and inspection of injectors").
13. Remove the throttle cable from the housing sector (see "Throttle body - removal and installation") and, having unscrewed the two bracket mounting bolts, we set aside the bracket with the cable (see "Receiver - removal and installation").
14. After loosening the clamps, remove the thermostat bypass hose and the radiator inlet hose.
15. After loosening the clamp, remove the hose for supplying coolant to the heater radiator from the pipe.
16. Disconnect the coolant outlet hose and air duct from the nozzles of the throttle body (see "Throttle body - removal and installation").
17. Disconnect the vacuum brake booster hose from the receiver pipe (see "Receiver - removal and installation").
18. Disconnect the fuel supply and drain hoses from the ramp tubes (see "Fuel rail - removal, installation and inspection of injectors").
19. socket wrench by 12 mm with an extension, unscrew the ten bolts of the internal fastening of the head to the cylinder block.
20. socket wrench by 13 mm unscrew the bolt of the external fastening of the head to the cylinder block.
21. Remove the cylinder head assembly with the intake manifold and exhaust manifold.
22. Remove the gasket from the two centering bushings of the cylinder block.
Installation
1. Install a new gasket and cylinder head in reverse order, passing a wire with a chain through their windows.
2. Before installing the cylinder head, it is necessary to lubricate the bolts of its fastening with engine oil in advance and allow excess oil to drain, holding the bolts for at least 30 minutes.
Attention! The cylinder head bolts may only be reused if they have extended to a length of no more than 115.5 mm. For longer lengths, the bolt must be replaced.
3. Tighten the block head bolts in four stages:
- pre-tighten ten bolts of the internal fastening of the head with a torque of 20 N·m;
- we tighten them with a moment of 69.4-85.7 N·m.
- we tighten the bolts by 90°;
- turn the screws 90°again.
Tighten the outer bolt last (11) torque 30.6-39.1 Nm.
The order of tightening the cylinder head bolts
4. We install the housing with the camshaft on the cylinder head studs and tighten the fastening nuts (see "Camshaft and valve levers - replacement").
5. We untie the wire, install the sprocket with the chain on the camshaft, wrap the mounting bolt and counter it by bending the tab of the lock washer.
6. "We charge" chain tensioner and, having installed it in its original place, "unloading" (see "Timing chain tensioner - replacement") and adjust chain tension (see "Timing Chain - Tension Adjustment").
7. Adjust the gap between the levers and camshaft cams (see "Clearance between valve levers and camshaft lobes - adjustment").
8. Installation of the removed parts is carried out in reverse order.
9. Fill the system with coolant (see "Coolant - level check and replacement").
