GENERAL INFORMATION
M2112000101010
The 4G15-MIVEC-T/C engine employed in the Colt
is designed to provide higher performance and
higher output by using a turbocharger to the
4G15-MIVEC engine employed in the conventional
Colt. The main changes in the conventional
4G15-MIVEC engine are as follows:•Cylinder head gasket changed
•Oil jet added
•Strength improved in piston and piston pin

Mitsubishi has given careful consideration to protec-
tion of natural resources and the environment in the
vehicle. Environmentally friendly features are shown
below.
IMPROVEMENT ON RECYCLING EFFICIENCY
ClassificationMain Components
Components made
of recycled
materialsChip materials produced during manufacturing process has been reused as the
following components: Door inside handle, bu mper, radiator grille, instrument panel,
door trims, or floor padding.
Waste materials produced by other i ndustries have been reused as the following
components: Engine oil level gauge, air filter casing, and sound absorbing materials
for dash panel
Components made
of materials which
can be easily
recycledThermoplastic resin has been utilised as the following components: Inside door
handle, bumper, radiator grille, instrument panel, door trim
Thermoplastic resin has been utilised as t he following components: Vacuum hose for
engine control, air intake hose, hood weather strip, tailgate opening weather strip
REDUCTION OF MATERIAL BURDEN ON ENVIRONMENT
ItemMain Components
Elimination of
environmental
burden materialsLead-free materials have been utilised as the following components: Radiator, fuel
tank, power steering oil pressure hose, el ectrodeposition paint for body, glass ceramic
print, heater core, battery terminals, wiring harness
Non-asbestos material has been used for engine gaskets.
PVC(polyvinyl chloride)-free materials ha ve been used for the waterproofing film.
Prevention of
ozone depletionAir conditioner filled with new refrigerant (HFC 134a) has been installed.
Prevention of air
pollutionEmployment of a metal cylinder head gasket reduces the volume of incomplete
combustion generated between the cylinder block and cylinder head, and suppresses
the level of unburned hydrocarbon (HC).
SERVICEABILITY AND RELIABILITY

MULTI USE TESTER-III (M.U.T.-III) SUB
ASSEMBLY
Comprehensive improvements have been made to
the M.U.T.-II, a tester for diagnosing problems with
the electronic control system. For easier servicing,
the newly developed M.U.T.-III has greatly improved
functions and is much easier to use. The M.U.T.-III
expands the functions of the M.U.T.-II in the following
ways:
1.CAN* bus diagnosis
•Auto diagnosis function for the CAN commu-
nications bus line is added.
NOTE: *CAN: Controller Area Network (for further
details, refer to GROUP 54C
P.54C-2).
