Disassembly of 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 cylinder head.
IMPORTANT
Mark all valve train components so they can
be installed in their original locations.
Note: Record all measurements taken during
disassembly.
1. Drain coolant from engine into a suitable
container. See Drain, Flush and Refill Cooling
System with New Coolant on page 5-33.
2. Remove the coolant pump. See Disassembly of
Engine Coolant Pump on page 8-7.
3. Remove the high-pressure fuel lines and fuel
injectors from the cylinder head. See Removal
of Fuel Injectors on page 7-23.
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.
