Engine Front Cover Installation

NOTICE!

The engine front cover is made of composite material
and has an intergral gasket. Once the front cover is re-
moved, it must be discarded and a new front cover
must be used.

1.

Install the NEW engine front cover.

2.

Install the engine front cover bolts and tighten to 12 N•m (106
lb. in).

NOTICE!

DONOT reuse the original crankshaft position sensor
seal (o-ring). When installing the crankshaft position
sensor, be sure the crankshaft position sensor is fully
seated and held stationary in the engine front cover
crankshaft position sensor bore. A crankshaft posi-
tion sensor that is not completely seated will cock in
the engine front cover and may result in erratic engine
operation.

3.

Lubricate the NEW crankshaft position sensor seal (O-ring) with
clean engine oil.

4.

Install the NEW crankshaft position sensor seal (O-ring) onto
the crankshaft position sensor.

5.

Install the crankshaft position sensor until fully seated into the
engine front cover.

6.

Install the crankshaft position sensor bolt and tighten to 9 N•m
(80 lb. in).

7.

Install oil pan,

Oil Pan and OIl Pump

8.

Install crankshaft balancer,

Crankshaft Balancer

9.

Install engine circulation pump,

10.
