Removal

1 Drain the coolant from the engine block and radiator (see Chapter 1).

2 Drain the engine oil and remove the oil filter (see Chapter 1).

3 Remove the throttle body, fuel injectors, fuel rail, intake and exhaust manifolds (see Chapter 4A).

4 Remove the timing belt and camshaft sprocket (see Sections 5 and 9).

5 Remove the alternator and distributor (1.6 litre engine only) - see Chapter 5A and 5B.

6 Unbolt the power steering pump and set the pump aside without disconnecting the hoses.

7 Remove the coolant junctions from each end of the cylinder head.

8 Remove the timing chain as described in Section 6.

All engines

10 Remove the camshafts and followers (see Section 10).

11 Label and remove any remaining items, such as coolant fittings, tubes, cables, hoses or wires.

12 Using an 8 mm Allen key bit (Non-VVT-i engines) or an M12 bi-hexagon bit (VVT-i engines), loosen the cylinder head bolts in

1/4-turn increments until they can be removed by hand. Loosen the cylinder head bolts in the reverse of the recommended tightening sequence (see illustrations 11.25a, 11.25b or 11.27) to avoid warping or cracking thecylinder head. Recover the washers.

13 Lift the cylinder head off the engine block. If it's stuck, very carefully pry up at the transmission end, beyond the gasket surface

(see illustration).

14 Remove all external components from the cylinder head to allow for thorough cleaning and inspection. See Chapter 2B, for cylinder head servicing procedures.

15 The mating surfaces of the cylinder head and block must be perfectly clean when the cylinder head is installed.
