Disassembly of 4-Valve Cylinder
Head
Prepare a clean, flat working surface on a
workbench large enough to accommodate the
cylinder head assembly. Discard all gaskets,
O-rings and seals. Use new gaskets, O-rings and
seals on reassembly of the cylinder head.
1. Drain the coolant from the engine into a suitable
container. See Drain, Flush and Refill Cooling
System With New Coolant on page 5-36.
2. Remove the high pressure fuel injection lines
(Figure 6-40, (1)). See Removal of Fuel
Injectors on page 7-35.
Figure 6-40
CAUTION
Identify all parts and their location using
an appropriate method. It is important
that all parts are returned to the same
position during the reassembly process.
