age the engine. The cause of excessive spark knock
condition must be diagnosed and corrected. For diag-
nostic proedures refer to Group 14, Fuel System and
Powertrain Diagnostic Procedures manual.
3.3 L ENGINES
Use only unleaded gasoline having a minimum oc-
tane rating of 87.
3.5 L ENGINES
Use of mid-grade unleaded fuel with minimum oc-
tane rating of 89 is recommended. Regular unleaded
gasoline having a minimum octane rating of 87 can be
used. Regular fuel can reduce engine performance
and fuel mileage. Premium unleaded gasoline having
a minimum octane rating of 91 can be used if desired.
Refer to Group, 14 for additional information.
FLEXIBLE FUEL ENGINES
CAUTION: Do not use 100% methanol, damage to
fuel system can result.
Use unleaded regular gasoline having a minimum
octane rating of 87 (R=M)/2 and M85 fuel that is 85%
methanol and 15% unleaded gasoline, or a mixture of
these two.
SELECTING GASOLINE
CAUTION: Do not use fuel containing METHANOL
(methyl or wood alcohol) in non-flexible fuel en-
gines, damage to fuel system will result.
Do not use leaded gasoline, damage to catalytic
converter will result and vehicle will not conform to
emission control standards.
ETHANOL, MTBE OR ETBE BLENDS
All Chrysler Corporation vehicles are designed to
use unleaded gasoline ONLY. Gasohol blends, con-
taining 10% Ethanol (ethyl or grain alcohol) 90%
unleaded gasoline can be used provided it has ad-
equate octane rating.
Fuel blends containing up to 15% MTBE (Methyl
Tertiary Butyl Ether) and 85% unleaded gasoline can
be used. Fuel blends containing up to 17% ETBE
(Ethyl Tertiary Butyl Ether) and 83% unleaded gaso-
line can also be used.
Fuel blended with ethanol, MTBE or ETBE are also
referred to as reformulated or clean air gasoline.
These fuels contribute less emissions to the atmo-
sphere. Chrysler Corporation
blended fuels be used when available.
METHANOL BLENDS
Using gasoline blended with methanol in non-
flexible fuel engines can result in starting and drive-
ability problems. Deterioration of fuel system compo-
recommends that
nents will result. Methanol induced problems are not
the responsibility of Chrysler Corporation and may
not be covered by the vehicle warranty.
FUEL FILTER
The fuel filter requires service only when a fuel
contamination problem is suspected. For proper diag-
nostic and service procedures refer to Group 14, Fuel
System.

IGNITION CABLES

Inspect and test ignition cables when the spark
plugs are replaced. Oil and grime should be cleaned
from the ignition cables and coil to avoid possible
spark plug fouling. Mopar Foamy Engine Degreaser,
or equivalent is recommended for cleaning the engine
compartment. For proper service and diagnostic pro-
cedures refer to Group 8D, Ignition Systems.
SPARK PLUGS
Ignition spark plugs should be replaced at the mile-
age interval described in the Lubrication and Mainte-
nance Schedules. Refer to the General Information
section of this group. For proper service procedures
refer to Group 8D, Ignition Systems.
DRIVE BELTS
Inspect and adjust drive belts at the interval de-
scribed in the Lubrication and Maintenance Sched-
ules. Refer to General Information section of this
group. For proper inspection and adjustment proce-
dures refer to Group 7, Cooling System.
EMISSION CONTROL SYSTEM
Inspect all emission control components and hoses
when other under hood service is performed. Refer to
emission system Vacuum Hose Label located on the
inside of the hood in the engine compartment and
Group 25, Emission Control Systems for proper ser-
vice procedures.

BATTERY

Inspect battery tray, hold down and terminal con-
nections when other under hood service is performed.
For proper diagnostic procedures refer to Group 8A,
Battery/Starting/Charging System Diagnostics. For
service and cleaning procedures refer to Group 8B,
Battery/Starter Service.
