Special tools and equipment required
- Mot. 591-04 Angled key for tightening cylinder head bolts and magnetic support indicator for angular tightening of bolts.
- Mot. 1202 Pliers for elastic clamps.
- Mot. 1273 Belt tension gauge.
- Mot. 1379 Device for fixing the engine on the subframe.
- Torx socket head for 12.
- Angle measuring disc for angular tightening.
Tightening torques, Nm
- Crankshaft pulley mounting bolt: 20 + 90°.
- Front right swingarm suspension bracket mounting bolt on engine: 62.
- Bolt for fastening the front right pendulum suspension bracket to the body: 62.
- Timing belt tension roller fastening nut: 50.
- Wheel mounting bolts: 90.
Removal
1. Place the vehicle on a two-post lift.
2. Remove the hood, right wheel.
3. Disconnect the battery.
4. Drain the fluid from the cooling system.
5. Install Moi 1379 shims to secure the engine to the subframe.
6. Remove:
- timing belt (see section "Gas distribution mechanism drive belt");
- oil dipstick;
- brake booster vacuum hose;
- air filter;
- throttle cable;
- fuel supply and return lines from the upper timing drive cover.
7. Disconnect:
- spark plug wires using device 3, built into protective plastic casing 4;
- the absorber tube, as well as the hoses of the fuel vapor recovery system from the electromagnetic valve:
- connectors for the ignition module, injectors, idle speed control stepper motor and throttle position potentiometer;
- idle speed controller stepper motor;
- throttle position potentiometer;
- air temperature sensor.
8. Remove the hose connecting the water pump to the heater core and disconnect the electrical harness from the heat shield on the valve cover.
9. Remove:
- 5 throttle body bracket mounting bolts on cylinder head;
- nuts of studs fastening 3 manifold to cylinder block;
- bolts for fastening 4 manifolds to the valve cover;
- an assembly consisting of an intake manifold, a throttle body and a fuel distribution rail.
10. Remove:
- hoses from thermostat;
- valve cover,
- cylinder head mounting bolts;
- cylinder head.
Cleaning and checking
Caution! Do not clean the mating surfaces of aluminum parts with a tool with a sharp edge. Use Decapjoint to dissolve adhering gasket residues.
1. Apply the composition to the surface to be cleaned. Wait about ten minutes, then remove the stuck remains of the gasket with a wooden spatula. It is recommended to perform this operation with gloves.

Caution! This operation must be carried out carefully to avoid foreign particles from entering the pressurized oil supply system to the camshaft (the channels are located in the cylinder block and cylinder head).
Failure to comply with this requirement may result in clogging of the rocker arm jets and cause rapid wear of the cams and rocker arm bearing surfaces.
2. Check the deformation of the mating surface. The maximum permissible non-flatness is 0.05 mm.
3. Check the cylinder head for cracks.
Installation
1. The cylinder head is centered by two bushings located at the rear of the engine.
Caution: To ensure proper tightening of the bolts, remove any remaining oil that may be in the cylinder head bolt holes using a syringe.
2. Lubricate the threads and the bottom of the bolt heads with engine oil.
5. Tighten the cylinder head bolts using a protractor disc for angular tightening of the bolts (see Chapter "Maintenance").
6. Align the marks on the timing belt with the marks on the toothed pulleys.
7. Install the timing belt (see section "Gas distribution mechanism drive belt").
8. If necessary, adjust the clearances in the valve drive mechanism (see chapter "Maintenance").
9. Perform installation in the reverse order of removal.
Attention! Tightening of intake manifold fastening parts:
- - gradually tighten the six nuts until the manifold contacts the cylinder head, then tighten the nuts to 15 Nm;
- - install the upper bolts and tighten them to a torque of 9 Nm.
10. Remove the Mot. 1379 engine mounting pads on the subframe.
11. Fill with coolant and bleed the cooling system (see chapter "Maintenance").
12. Adjust the throttle cable.
