GENERAL INFORMATION

INTRODUCTION
This service manual supplement has been
developed to provide the service technician
with the basic understanding of the IMPCO
certified fuel and emission systems for the
2.0L engine. This manual should be used in
conjunction with the base engine manual and
the OEM service manual when diagnosing
fuel or electrical problems.
HOW TO IDENTIFY THE ENGINE YEAR
The 2.0L engine blocks have been stamped
with a serial number. The number can be
found on the left side of the top edge of the
engine block near the exhaust manifold.

SERVICING YOUR EMISSIONS
CERTIFIED ENGINE
Any maintenance and repair should be per-
formed by trained and experienced service
technicians. Proper tools and equipment
should be used to prevent injury to the servic-
ing technician and damage to the vehicle or
components. Service repairs should always
be performed in a safe environment and the
technician should always wear protective
clothing to prevent injury.
For parts or labor to be reimbursed under the
IMPCO Technologies Inc. emission warranty,
only work performed by IMPCO or OEM
trained technicians using only IMPCO speci-
fied parts will qualify for reimbursement.
Refer to the IMPCO Labor Time Guide for ad-
ditional information.
For parts or labor not reimbursed under war-
ranty, a repair shop or person of the owner’s
choosing may maintain, replace, or repair
emission-control devices and systems. It is
highly recommended that any replacement
parts used for maintenance or for the repair of
emission control systems be new OEM re-
placement parts. The use of other than
genuine IMPCO replacement parts may im-
pair the effectiveness of emission control
systems, therefore, the owner should assure
that such parts are warranted by their manu-
facturer to be equivalent to genuine IMPCO
OEM parts in performance and durability.
FUEL QUALITY
LPG
Note that LPG engines are designed to operate
on HD–5 or HD–10 specification LPG fuel. Fuel
other than HD–5 or HD–10 may cause harm to
the engine’s emission control system and a war-
ranty claim may be denied on this basis if
operators can readily find the proper fuel*.
Use of any other fuel may result in your engine no
longer operating in compliance with CARB or
EPA emissions requirements.
*Not Applicable in the state of California.
