REPAIR INSTRUCTIONS, PART 2
Page 421
4. Reinstall the non-current design EECU
cooling plate as follows:
Non-Current Cooling Plate Design
The EECU cooling plate used on ASET™
AC engines from the beginning of production
through mid-May 2003 has two 0.580-inch
(14.7 mm) diameter mounting holes at the
lower corners of the plate. The lower
mounting isolators are installed through
these holes, and each isolator is then
secured with two 0.188-inch thick washers
and one nut.
Due to tolerance stack-up between the
thickness of the cooling plate and the
dimensions of the isolators, some isolators
may not clamp onto the cooling plate when
the nut is tightened. When this occurs,
tightening the nut further will cause the
washers to rotate, which places force on the
rubber portion of the isolator, resulting in
tearing or breaking of the rubber. To prevent
this from occurring, it is recommended that
another washer (part No. 35A1446X) be
added between the two 0.188-inch washers.
This should be done whenever the EECU or
cooling plate is removed for any reason, or if
torn or broken mounting isolators are
encountered.
a. For the non-current cooling plate
design, upper isolators are secured
with flanged nuts only; washers are not
used. The upper mounting nuts must
be tightened to 108 lb-in (12 N폷m).
b. Non-current lower mounting nuts must
be tightened to 180 lb-in (20 N폷m).
5. Reinstall the current
design EECU cooling
plate as follows:
Current Cooling Plate Design
Beginning 5/15/03, the EECU cooling plate
arrangement used on the ASET™ AC
engines was changed to include integral
bushings at the two lower mounting bolt
holes. The lower mounting isolators are
installed through these bushings and
secured by one 0.065-inch thick washer and
one nut.
a. For the current cooling plate design,
upper isolators are secured with
flanged nuts only; washers are not
used. The upper mounting nuts must
be tightened to 108 lb-in (12 N폷m).
b. Current design lower mounting nuts
must be tightened to 180 lb-in (20 N폷m).
Final Assembly
Reinstall all accessory items, ducting, etc., that
were removed to gain access to the EGR
components. Replace all fluids drained from the
engine and reconnect the batteries.
