GENERAL INFORMATION

In this model year Chrysler began producing AA-

Body vehicles designed to operate on a mixture of
gasoline and methanol. These automobiles are referred
to as Flexible Fuel vehicles. Fuel system components
designed for use in flexible fuel vehicles are referred to
as Methanol Compatible.

Flexible fuel vehicles can operate on a mixture of up

to 85 percent methanol, 15 percent unleaded gasoline.
These vehicles also operate on mixtures containing a
lower percentage of methanol or just pure unleaded
gasoline.

SERVICE PRECAUTIONS FOR FLEXIBLE FUEL
VEHICLES

Methanol is more toxic than gasoline. Always release

fuel system pressure before servicing fuel system com-
ponents and wear methanol resistant gloves and eye
protection.

Avoid breathing methanol vapors or ingesting

methanol. Headaches, dizziness and even unconscious-
ness could result from breathing these vapors. Serious
injury, blindness and even death could result from
ingesting methanol.

Methanol vapors are extremely flammable and can

travel along the ground. Service vehicles in well ven-
tilated areas and avoid ignition sources. Never smoke
while servicing the vehicle.

Do not allow methanol to contact skin. Prolonged

contact with methanol can cause dry skin or an allergic
skin reaction. Also, prolonged contact could result in
absorption through the skin.

IDENTIFYING FLEXIBLE FUEL COMPONENTS

Flexible Fuel vehicles have unique methanol compat-

ible fuel system components. Chrysler identifies methanol
compatible components that could be physically inter-
changed with gasoline only parts by coloring them green
or applying a green label or tag to them. Even though
they may appear physically identical, components
for gasoline only AA-body vehicles must not be used
on flexible fuel vehicles.

FLEXIBLE FUEL COMPONENTS

The fuel system of flexible fuel AA-body vehicles have

the following unique methanol compatible components.
• Duty cycle EVAP purge solenoid

• EVAP canister

• Fuel pump module

• Fuel level sensor

• Fuel gauge (gauge cluster).

• Fuel tank

• Fuel pressure regulator (including O-rings)

• Fuel rail

• Fuel injectors (including O-rings)

• Fuel tubes

• Fuel filter

• Fuel filler cap

• Fuel filler tube

• Methanol concentration sensor

• Pressure relief/rollover valve

• PCV Valve

• All fuel system and emission system hoses and tubes

THROTTLE BODY

WARNING: THROTTLE BODIES DESIGNED FOR
GASOLINE ONLY VEHICLES CANNOT BE USED ON
FLEXIBLE FUEL AA-BODY VEHICLES. WHEN RE-
PLACING THE THROTTLE BODY OF A FLEXIBLE
FUEL VEHICLE, ONLY USE AN ORIGINAL EQUIP-
MENT REPLACEMENT.

When servicing throttle body components, always

reassemble components with new O-rings and seals
where applicable. Never use lubricants on O-rings or
seals, damage may result. If assembly of component is
difficult, use water to aid assembly. Use care when
removing hoses to prevent damage to hose or hose
nipple.
