tect the cooling system to -37°C (-35°F). If the freeze protection is above -28°C (-20°F), drain enough coolant from the cooling system to allow room to add antifreeze to achieve adequate protection. A mix table on the coolant container indicates the amount of antifreeze required to winterize the cooling system based on the capacity, see Capacity Chart in General Information section of this group.

SELECTING ANTIFREEZE

Chrysler Corporation recommends Mopart Antifreeze/Summer Coolant, or equivalent be used to winterize and protect cooling system.

RADIATOR CAP

The radiator cap must be secure to provide proper pressure release and coolant recovery. Inspect and test radiator cap when cooling system service is performed or when problem is suspected.

COOLING SYSTEM SERVICE

The cooling system should be drained, flushed and filled with the proper coolant mixture at the intervals described in the Lubrication and Maintenance Schedules. Refer to General Information section of this group. For proper service instructions see Group 7, Cooling System.

ENGINE AIR CLEANER

The engine air cleaner should be serviced at the intervals described in the Lubrication and Maintenance Schedules. Refer to General Information section of this group. Additional information can be found in Group 14, Fuel System and Group 25, Emission System. Inspect all air cleaner hoses or tubes for damage or leaks when other engine compartment service is performed. Replace faulty components.

AIR CLEANER SERVICE

CAUTION: The air cleaner cover must be installed properly for the emissions system and engine controller to function correctly.

Do not immerse paper air filter element or temperature sensor in cleaning solvents, damage can result.

TO SERVICE AIR CLEANER ASSEMBLY:

(1)Raise hood of vehicle and inspect all air cleaner components for damage or improper attachment.

(2)Remove air cleaner cover (Figs. 7, 8, 9, 10 or

11).

(3)Remove paper air filter element from air cleaner body. Hold a shop light on throttle body side of element. Inspect air intake side of element. If light is visible through element, blow dust from element (Fig. 12) and reuse. If element is saturated with oil or light is not visible, replace filter. If element is saturated with oil, perform crankcase ventilation system tests.

CRANKCASE VENTILATION SYSTEM

Engine crankcase pressure and emissions are vented into combustion chambers through the positive crankcase ventilation (PCV) system. The PCV system consists of a crankcase filter (Figs. 7, 8, 9, 10 or 11), PCV valve (Figs. 13, 14, 15 or 16) and hoses to complete a vacuum circuit. The PCV system should have enough volume to overcome crankcase pressure created by piston backwash. If a PCV system becomes plugged, the crankcase pressure will increase and force engine oil past the piston rings creating oil consumption. Blockage of PCV system can occur at the vacuum source coupling, PCV valve, crankcase filter or a collapsed hose.

Chrysler Corporation recommends that a PCV valve not be cleaned. A new Mopart or equivalent PCV valve should be installed when servicing is required. Over a period of time, depending on the environment where vehicle is used, deposits build up in the PCV vacuum circuit. PCV system should be inspected at every oil change. Service PCV system if engine oil is discharged into air cleaner.

PCV SYSTEM TEST

(1)Verify that fiber crankcase filter is clean and properly installed in the air cleaner assembly.

(2)With the engine running at idle, remove crankcase inlet hose from the inlet filter nipple. Position a 50 mm (2 in.) square paper card over end of inlet hose. The card should be drawn to the end of the inlet hose within 15 seconds. If not, a leak or restriction exists in the PCV vacuum circuit.

(3)If card does not hold to end of inlet hose, disconnect PCV valve from cylinder head cover or adapter. Vacuum hissing sound should be heard and engine should run steady. Place a finger over end of PCV valve (Fig. 17). The check valve in the PCV valve should click and rattle when PCV valve is shaken.

(4)Remove PCV valve from vacuum source hose. The engine should run very erratically or stall. If not, a vacuum restriction or blockage exists at the vacuum source.

FUEL RECOMMENDATIONS

Chrysler Corporation recommends that only fuel purchased from a reputable retailer be used. Use high quality, unleaded gasoline to provide satisfactory driveability and highest fuel economy. Gasoline containing detergent and corrosion control additives are desireable. If the engine develops spark knock (audible ping), poor performance, hard starting or stalling, purchase fuel from another source. Engine performance can vary when using different brands of gasoline with the same octane rating. Occasional light engine spark knock under heavy acceleration, at low speed or when vehicle is heavily loaded is not harmful. Extended periods of spark knock under moderate acceleration or at cruising speed can damage the engine. The cause of excessive spark knock condition must be diagnosed and corrected. For diagnostic procedures refer to Group 14, Fuel System and Powertrain Diagnostic Procedures manual.

SELECTING GASOLINE

CAUTION:Do not use fuel containing METHANOL (methyl or wood alcohol), 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, containing 10% Ethanol (ethyl or grain alcohol) 90% unleaded gasoline can be used provided it has adequate 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 gasoline 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 atmosphere. Chrysler Corporation recommends that blended fuels be used when available

METHANOL BLENDS

Using gasoline blended with methanol can result in starting and driveability problems. Deterioration of fuel system components will result. Methanol induced problems are not the responsibility of Chrysler Corporation and may not be covered by the vehicle warranty.

NON-TURBOCHARGED ENGINES

Use regular unleaded gasoline having a minimum octane rating of 87 (R+M)/2. Higher octane premium unleaded gasoline can be used if desired.

2.2L AND 2.5L TURBOCHARGED ENGINES

Use any high quality unleaded gasoline having a minimum octane rating of 87 (R+M)/2. Gasoline with octane rating greater than 87 (R+M)/2 will improve engine performance.

2.2L 16 VALVE TURBOCHARGED ENGINE

Use premium unleaded gasoline having a minimum octane rating of 91 (R+M)/2. Gasoline with octane rating less than 91 (R+M)/2 can be used if recommended gasoline is not available. Low octane gasoline will reduce engine performance.

FUEL FILTER

The fuel filter requires service only when a fuel contamination problem is suspected. For proper diagnostic and service procedures refer to Group 14, Fuel System.
