AN
OIL PUMP (Continued)
The pump incorporates a nonadjustable pressure
relief valve to limit maximum pressure to 517 kPa
(75 psi). In the relief position, the valve permits oil to
bypass through a passage in the pump body to the
inlet side of the pump.
Oil pump removal or replacement will not affect
the distributor timing because the distributor drive
gear remains in mesh with the camshaft gear.
(1) Install the oil pump on the cylinder block using
a replacement gasket. Tighten the bolts to 23 N·m
(17 ft. lbs.) torque.
(2) Install the oil pan and gasket (Refer to 9 -
ENGINE/LUBRICATION/OIL PAN - INSTALLA-
TION).
(3) Fill the oil pan with oil to the specified level.
INTAKE MANIFOLD
DESCRIPTION
The aluminum intake manifold is a single plane
design.
The intake manifold and the exhaust manifold
share a common one piece sealing gasket.
DIAGNOSIS AND TESTING - INTAKE
MANIFOLD
An intake manifold air leak is characterized by
lower than normal manifold vacuum. Also, one or
more cylinders may not be functioning.
WARNING: USE EXTREME CAUTION WHEN THE
ENGINE IS OPERATING. DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR
HANDS NEAR THE PULLEYS, BELTS OR THE FAN.
DO NOT WEAR LOOSE CLOTHING.
(1) Start the engine.
(2) Spray a small stream of water at the suspected
leak area.
(3) If a change in RPM is observed the area of the
suspected leak has been found.
(4) Repair as required.
REMOVAL
(1) Disconnect the battery negative cable.
(2) Drain the cooling system (Refer to 7 - COOL-
ING - STANDARD PROCEDURE).
(3) Remove the air inlet hose and resonator from
the throttle body and air cleaner (Fig. 76).
(4) Loosen the accessory drive belt tension and
remove the belt from the power steering pump (Refer
to 7 - COOLING/ACCESSORY
BELTS - REMOVAL).

(5) Remove the power steering pump and brackets
from the water pump and intake manifold. Secure
power steering pump and bracket out of the way.
(6) Perform fuel system pressure release procedure
(Refer to 14 - FUEL SYSTEM/FUEL DELIVERY -
STANDARD PROCEDURE).
(7) Disconnect fuel supply tube from the fuel rail
(Refer to 14 - FUEL SYSTEM/FUEL DELIVERY/
QUICK CONNECT FITTING - STANDARD PROCE-
DURE).
(8) Disconnect the accelerator cable, the cruise
control cable (if equipped), and the transmission line
pressure cable (if equipped) from the throttle body
and remove them from the cable bracket.
CAUTION: When disconnecting the cruise control
connector at the throttle body, DO NOT pry the con-
nector off with pliers or screwdriver. Use finger
pressure only. Prying the connector off could break
it.
(9) Disconnect the electrical connectors. Pull the
harnesses away from the manifold and secure them
so they do not interfere with the manifold removal
and installation process.
DRIVE/DRIVE
• The throttle position sensor.
• The idle air control motor.
• The coolant temperature sensor at the thermo-
stat.
