Removal
Refer to illustrations 13.10, 13.17 and 13.12
1 Position the number one piston at Top Dead Center (TDC) (see Sec-
tion 3).
2 Disconnect the negative cable from the battery.
3 Drain the cooling system and remove the spark plugs (see Chapter
1).
4 Remove the intake manifold (see Section 11).
5 Remove the exhaust manifold (see Section 12).
6 Remove the distributor (see Chapter 5), including the cap and wires.
7 On carbureted models, remove the fuel pump (see Chapter 4,).
8 Remove the timing belt (see Section 8). Note: On some mode/s it is
possible to remove the cylinder head without removing the timing belt.
Hang the sprocket with a piece of wire attached to the hood of the vehicle -
make sure the belt does not lose tension after the camshaft sprocket has
been detached from the camshaft.
9 Remove the valve cover (see Section 4).
10 Using an 8 mm Allen head socket, loosen the cylinder head bolts,
1 M-turn at a trme, in the sequence shown (see illustration) until they can
be removed by hand.
11 Carefully lift the cylinder head straight up and place it on wood blocks
to prevent damage to the sealing surfaces. If the head sticks to the engine
block, dislodge it by placing a block of wood against the head casting and
tapping the wood with a hammer or by prying the headwith a prybarplaced
carefully on a casting protrusion (see illustration). Cylinder head disas-
sembly and inspection procedures are covered in Chapter 2, Part D. It’s a
good idea to have the head checked for warpage, even if-you’re just re-
placing the gasket.
12 Remove all traces of old gasket material from the block and head (see
illustration). Do not allow anything to fall into the engine. Clean and in-
spect all threaded fasteners and be sure the threaded holes in the block
are clean and dry.
Ins talla tion
Refer to illustrations 13.13 and 73.14
13 Place a new gasket and the cylinder head in position. Note: Positi
the identification mark facing up and at the front of the engine block (see
illustration).
14 The cylinder head bolts should be tightened in several stages follow:
ing the proper sequence (see illustration) to the torque listed in this
Chapter’s Specifications.
15 Reinstall the timing belt (see Section 8).
16 Reinstall the remaining parts in the reverse order’of removal. ’
17 Be sure to refill the cooling system and check all fluid levels. Rotate
the crankshaft clockwise slowly by hand through two complete revoiu-
tions. Recheck the camshaft timing marks (see Section 8).
18 Start the engine and set the ignition timing (see Chapter I): Run the
engine until normal operatmg temperature is reached. Check for leaks and
proper operation. Shut off the engine. Remove the valve cover and retigh-
ten the cylinder head bolts, unless the gasket manufacturer states other-
wise. Recheck the valve adjustment if the engine is not equipped with
hydraulic lash adjusters.

Removal
1 Disconnect the negative cable from the battery.
2 Raise the vehicle and support it securely on jackstands.
3 Remove the splash pan under the engine, then remove the dipstick
and drain the engine oil (see Chapter 1).
