REMOVAL AND INSTALLATION (Continued)
INSTALLATION
(1) Apply a small amount of engine oil to the sen­
sor o-ring (Fig. 55).
(2) Install the sensor Into the cylinder block with a
slight rocking action. Do not twist the sensor into
position as damage to the o- ring may result.

bolt, be sure the sensor is completely flush to the
cylinder block (Fig. 54). If sensor is not flush, dam­
age to the sensor mounting tang may result.
(3) install the mounting bolt and tighten to 8 N-m
(70 in. lbs.) torque.
(4) Connect sensor wiring harness and lower the
vehicle.

V-10 Engine
A thin plastic rib is molded Into the face of the sen­
sor (Fig. 58) to position the depth of sensor to the
upper cam gear (sprocket). This rib can be found on
both the new replacement sensors and sensors that
were originally installed to the engine. The first time
the engine has been operated, part of this rib may be
sheared (ground) off. Depending on parts tolerances,
some of the rib material may still be observed after
removal.
