Execution sequence
1. We prepare the car for work (see «Preparing the car for maintenance and repair»).
Comment. For the convenience of working on the Zafira model, it is necessary to remove the ventilation grill and the top panel of the motor shield (see «Front wiper drive Zafira - check and replace»).
2. Drain the oil (see «Lubrication system - oil and oil filter change») and coolant (see «Coolant - replacement»),
3. Remove the intake manifold from the studs of the head of the block and take it back (see «1.8 DOHC engine intake manifold - gasket replacement»).
4. Remove the rear timing belt cover (see «Camshaft seals - replacement»).
5. Disconnect the cooling system hose from the thermostat (see «Thermostat - check and replacement»).
6. We remove the exhaust manifold from the cylinder head (see «Exhaust manifold - gasket replacement»).
7. Disconnect the wiring harness block from the exhaust gas recirculation valve (see «EGR valve - replacement») and set the wiring harness aside.
8. Using the TORX E12 key, evenly, half a turn, unscrew the ten cylinder head bolts in the specified order.
9. Remove the cylinder head.
10. Remove the cylinder head gasket.
Recommendation. When replacing the head gasket, we strongly recommend checking the cylinder head (see «Cylinder head - check»).
11. We clean the mating surface of the cylinder block and pistons from oil deposits, remove carbon deposits from the bottoms of the pistons with a metal brush.
12. Install a new cylinder head gasket, aligning the holes with the block head guides. The inscription OBEN/TOP must be directed upwards.
13. We install the remaining parts in the reverse order, we tighten the bolts with the prescribed torque (see «Reference data») in that order.
