AIR CLEANER ELEMENT
REMOVAL
(1) Disconnect negative battery cable.
(2) Disconnect inlet air temperature sensor electri-
cal connector.
(3) Disconnect fresh air makeup hose from throttle
body air inlet hose.
(4) Disconnect PCV hose from intake manifold.
(5) Loosen hose clamp at throttle body air inlet
hose. Remove hose from throttle body.
(6) Push in on locking tabs to disengage air inlet
hose from air cleaner housing. Remove throttle body
air inlet hose and air cleaner element together.
(7) Separate air cleaner element from throttle body
air inlet hose (Fig. 7).
INSTALLATION
(1) Clean any debris from inside air cleaner hous-
ing.
(2) Install air cleaner element onto throttle body
air inlet hose.
(3) Install throttle body air inlet hose into air
cleaner housing. Push in on hose until an audible
“click” is heard from locking tabs.
(4) Install hose on throttle body. Tighten hose
clamp.
(5) Connect PCV hose to intake manifold.
(6) Connect fresh air makeup hose.
(7) Connect inlet air temperature sensor electrical
connector.
(8) Connect negative battery cable.
AIR CLEANER HOUSING
REMOVAL
(1) Disconnect negative battery cable.
(2) Disconnect inlet air temperature sensor electri-
cal connector.
(3) Disconnect fresh air makeup hose from throttle
body air inlet hose.
(4) Loosen hose clamp at throttle body air inlet
hose. Remove hose from throttle body (Fig. 8).
(5) Remove push pin securing air duct to upper
radiator support.
(6) Remove nut on bracket that holds air cleaner
housing.
(7) Pull air cleaner housing straight up off locating
pins (Fig. 8).
INSTALLATION
(1) Install air cleaner housing straight down on
locating pins (Fig. 8).
(2) Install nut on bracket that holds air cleaner
housing and tighten.
(3) Install push pin that secures air duct to upper
radiator support.
(4) Install throttle body air inlet hose to throttle
body. Tighten hose clamp.
(5) Connect fresh air makeup hose.
(6) Connect inlet air temperature sensor electrical
connector.
(7) Connect negative battery cable.

CYLINDER HEAD
DESCRIPTION
The cross flow designed, aluminum cylinder head
contains dual over-head camshafts with four valves
per cylinder (Fig. 9). The valves are arrange in two
in-line banks. The intake valves face toward the
front of the vehicle. The exhaust valves face the dash
panel. The cylinder head incorporates powdered
metal valve guides and seats. The cylinder head is
sealed to the block using a multi-layer steel head
gasket and retaining bolts.
Integral oil galleries providing lubrication passages
to the hydraulic lash adjusters, camshafts, and valve
mechanisms.
DIAGNOSIS AND TESTING
CYLINDER HEAD GASKET
A cylinder head gasket leak can be located between
adjacent cylinders or between a cylinder and the
adjacent water jacket.
Possible indications of the cylinder head gasket
leaking between adjacent cylinders are:
• Loss of engine power
• Engine misfiring
• Poor fuel economy
Possible indications of the cylinder head gasket
leaking between a cylinder and an adjacent water
jacket are:
• Engine overheating
• Loss of coolant
• Excessive steam (white smoke) emitting from
exhaust
• Coolant foaming
CYLINDER-TO-CYLINDER LEAKAGE TEST
To determine if an engine cylinder head gasket is
leaking between adjacent cylinders, follow the proce-
dures in Cylinder Compression Pressure Test (Refer
to 9 - ENGINE - DIAGNOSIS AND TESTING). An
engine cylinder head gasket leaking between adja-
cent cylinders will result in approximately a 50–70%
reduction in compression pressure.
CYLINDER-TO-WATER JACKET LEAKAGE TEST
WARNING: USE EXTREME CAUTION WHEN THE
ENGINE IS OPERATING WITH COOLANT PRES-
SURE CAP REMOVED.
VISUAL TEST METHOD
With the engine cool, remove the coolant pressure
cap. Start the engine and allow it to warm up until
thermostat opens.
If a large combustion/compression pressure leak
exists, bubbles will be visible in the coolant.
COOLING SYSTEM TESTER METHOD
WARNING: WITH COOLING SYSTEM TESTER IN
PLACE, PRESSURE WILL BUILD UP FAST. EXCES-
SIVE
PRESSURE
BUILT
UP,
BY
CONTINUOUS
ENGINE OPERATION, MUST BE RELEASED TO A
SAFE PRESSURE POINT. NEVER PERMIT PRES-
SURE TO EXCEED 138 kPa (20 psi).
Install Cooling System Tester 7700 or equivalent to
pressure cap neck. Start the engine and observe the
tester’s pressure gauge. If gauge pulsates with every
power stroke of a cylinder a combustion pressure
leak is evident.
CHEMICAL TEST METHOD
Combustion leaks into the cooling system can also
be checked by using Bloc-Chek Kit C-3685-A or
equivalent. Perform test following the procedures
supplied with the tool kit.
REMOVAL - CYLINDER HEAD
(1) Perform fuel system pressure release procedure
before attempting any repairs. (Refer to 14 -
