Engine Temperature Sensor (Breather Cover)
NOTE: Ensure part is clean, undamaged and free of
debris and make sure electrical connector has
seal in place.
1. Lightly lubricate engine temperature sensor O-ring
and install engine temperature sensor into breather
cover.
2. Torque sensor to 7.3 N·m (65 in. lb.).
3. Push electrical connector on engine temperature
sensor making sure a good connection is made.
Install Oil Sentry™ (if equipped)
1. Apply pipe sealant with Tefl on® (Loctite® 592™
PST
®
Thread Sealant or equivalent) to threads of Oil
Sentry
™
switch and install it into breather cover.
Torque to 4.5 N·m (40 in. lb.).
2. Connect wire lead (green) to Oil Sentry
™
terminal.
Install Blower Housing and Outer Baffl es
NOTE: Do not completely tighten screws until all items
are installed to allow shifting for hole alignment.
1. Slide blower housing into position over front edge of
inner baffl es. Start a few screws to hold it in place.
2. Position outer baffl es and secure using M6 screws.
Install M6 screws (20 mm long) into intake port side
of cylinder heads, including any lifting strap. Install 2
M6 screws (16 mm long) into exhaust port side of
cylinder head. Install 2 short M5 screws (10 mm
long) in upper mounting holes of outer baffl es (into
backing plate). Be sure any leads are routed out
through proper off sets or notches, so they will not be
pinched between blower housing and baffl es.
On ETB ECH EFI engines, push evap line clip into
#2 side outer baffl e to secure and reinstall clip
securing wiring harness to backing plate.
3. If removed, install ignition coils onto baffl es. Ensure
that any clips noted in disassembly are reinstalled.
Torque screws to 10.2 N·m (90 in. lb.).
On ETB ECH EFI engines with high output charging
system, secure wiring harness in clip on #1 side coil.
4. Insert and tighten all remaining blower housing and
baffl e screws with exception of rectifi er-regulator
grounding bracket/lead screw (standard charging
system).
Torque all blower housing and baffl e M6 screws
assembled into aluminum to 10.7 N·m (95 in. lb.) for
a new hole, or 7.3 N·m (65 in. lb.) for a used hole.
Torque all blower housing and baffl e M5 screws
assembled into sheet metal (backing plate) to 2.8
N·m (25 in. lb.) for new holes, or 2.3 N·m (20 in. lb.)
for used holes.
5. ETB ECH EFI engines with standard charging
system, install LPAC support bracket with fuse
holders. Torque screws to 10.7 N·m (95 in. lb.) for a
new hole, or 7.3 N·m (65 in. lb.) for a used hole.
6. Torque breather cover screws to 11.3 N·m (100 in.
lb.) into new holes or 7.3 N·m (65 in. lb.) into used
holes in sequence shown. Note fi rst screw is torqued
a second time.
7. ETB ECH EFI engines with standard charging
system, install fuses and diagnostic connector into
bracket.
Install Rectifi er-Regulator (Standard Charging
System)
B
A
C
A Ground Strap
B Ground Lead
C Ground Lug
NOTE: Rectifi er-regulator middle terminal (B+) is off set
(not equally spaced) from outer terminals (AC).
Verify rectifi er-regulator plug is assembled to
match terminal off set of rectifi er-regulator.
1. Install rectifi er-regulator in blower housing if
removed previously. Reinstall any washers and hose
clamps.
a. If engine has ground strap, secure it against outer
side of rectifi er-regulator with a silver or green
plated screw.
b. If engine has ground lead that secures in same
hole as rectifi er-regulator fastener, secure one
end to rectifi er-regulator and other end to backing
plate.
c. If engine has ground lead that secures in
separate ground lug fastener hole in rectifi er-
regulator, secure one end to ground lug and other
end to backing plate.
2. Torque black rectifi er-regulator screws to 1.4 N·m
(12.6 in. lb.).
a. Torque silver or green ground strap screw to
2.8 N·m (25 in. lb.) into new holes or 2.3 N·m
(20 in. lb.) into used holes.
b. Ground lead that secures in same hole as
rectifi er-regulator fastener, torque screw securing
to backing plate to 2.8 N·m (25 in. lb.) into new
holes or 2.3 N·m (20 in. lb.) into used holes.
c. Ground lead that secures in ground lug hole of
rectifi er-regulator and to backing plate, torque
screws to 5.6 N·m (50 in. lb.) into new holes or
4.0 N·m (35 in. lb.) into used holes.
3. Connect plug to rectifi er-regulator. If purple wire was
removed, verify locking tang is raised on terminal
and push wire terminal into plug prior to connecting
to rectifi er-regulator.
