ALIGNMENT CHECKING
An accurate method of determining the alignment of the
underbody uses a measuring tram gauge. The tram
gauge set used to perform the recommended measuring
checks must include a vertical pointer able to reach
457 mm (18 inches).
Two types of measurements can be made with a tram
gauge: direct point-to-point measurements and mea-
surements calculated on a horizontal plane (datum line)
parallel to the underbody. Point-to-point measurements
are generally taken on steering and suspension engine
compartment parts and simply require the vertical point-
ers to be set equally.
For horizontal plane measurements, the vertical pointers
must be set as specified for each point to be measured.
Dimensions-to-gauge holes are measured to the center
of the holes and flush to the adjacent surface metal un-
less otherwise specified. It is recommended that the di-
agonal dimensions to the cross-body be checked on
both sides in order to verify the dimensional accuracy of
the vehicle underbody.
FLOOR PAN INSULATORS
The floor pan insulators have been designed for the
higher floor pan temperatures that result from the use
of the catalytic converter in the exhaust system. There-
fore, when servicing a vehicle, it is essential that any in-sulators that may have been disturbed or removed be
reinstalled in the original sequence and location. Also, if
an insulator needs to be replaced, use only the insula-
tion specified for that location on the floor pan.
When servicing or replacing interior insulators, observe
the following instructions.
Install the insulators in the original position and se-
quence. Butt the pieces together in order to avoid
gapping or overlapping.
If it is necessary to replace an insulator, use only the
specified insulation.
Use the original part to determine the amount of re-
placement material required and as a template for
cutting and fitting the new piece to the floor pan.
When installing the insulator, do not enlarge any cut-
outs or holes that are used for the attachment of interi-
or parts such as the instrument panel or the floor
console.
Route the cross-body harness for interior parts over
the floor pan insulators. Clip it in the original location.
Do not apply spray-on deadeners or trim adhesives to
the top of the floor pan at the area directly over the
catalytic converter or the muffler.
Any insulator service repair or replacement should be
the same thickness, size, and location as the original
installation in the vehicle.

9O – 2 BUMPERS AND FASCIAS
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
BUMPERS
The bumper systems are installed with the body color
bumper and the general bumper according to the vehicle
grade.
The bumper systems are designed to sustain a collision
into a fixed barrier at 4 km/h (2.5 mph) without damage.
After absorbing the energy of a collision, these bumpersystems restore themselves to their original position.
Both the front and the rear bumpers feature an internal
foam energy absorber and a polymer fascia cover. The
front bumper consists of the bumper fascia and the im-
pact bar. Remove the fascia before removing the impact
bar. The rear bumper consists of the bumper fascia and
the bracket. Removal of rear bumper brackets can be
possible without removing the bumper fascia.
