Engine Type 1988-1989:
3.3L V6 (G-Engine), Overhead Valve, Multi-Point Fuel Injection.
Engine Type 1990-1993:
3.3L V6 (G-Engine), Overhead Valve, Multi-Point Fuel Injection. Some later models may have offered a 3.8L V6 (E-Engine) as well.
Horsepower 3.3L V6:
Approximately 147-150 hp (varies slightly by year and configuration).
Torque 3.3L V6:
Approximately 185-190 lb-ft (varies slightly by year and configuration).
Injection Type:
Electronic Multi-Port Fuel Injection (MPI).
Recommended Fuel:
Unleaded Regular Octane (87 AKI).
Transmission Type:
3-Speed Automatic (e.g., TorqueFlite A727 for some earlier variants) or 4-Speed Automatic (e.g., A604/41TE/42LE Electronically Controlled).
Optional Transmission:
Primarily automatic transmissions were offered. Manual transmissions were not typical for the Imperial model.
Electronic Control:
Later models (post-1989) featured electronically controlled automatic transmissions (e.g., 42LE) for improved shift quality and fuel economy.
NHTSA Ratings:
Specific NHTSA ratings for these model years are not readily available but reflect the safety standards of the era. Expect basic driver/passenger protection.
ABS:
Anti-lock Braking System (ABS) was available as an option on later models, particularly the fourth generation.
Airbags:
Driver's side airbag became standard on the fourth generation (1990-1993). Passenger airbags were not typically offered during this period.
Seatbelts:
Three-point front seatbelts and lap belts for rear passengers.
Oil Change Interval:
Typically every 3,000-5,000 miles or 6 months, whichever comes first, depending on driving conditions and oil type used.
Transmission Fluid Change:
Recommended every 30,000-50,000 miles, or more frequently for severe service. Refer to manual for specific fluid type and procedure.
Spark Plug Replacement:
Intervals vary by spark plug type, but typically between 30,000-60,000 miles for conventional plugs.
Engine Oil Spec:
API SG or SH rated oil, SAE 5W-30 or 10W-30 recommended for most ambient temperatures. Consult manual for specific viscosity based on climate.
Transmission Fluid Spec:
ATF+3 (Mopar) or equivalent is generally recommended for the 4-speed automatic transmission. Consult manual for exact specification.
Coolant Spec:
Chrysler's recommended ethylene glycol-based coolant with corrosion inhibitors. A 50/50 mix with distilled water is standard.
Common Engine Issues:
Head gasket leaks (especially on 3.3L V6), oil leaks from valve covers and oil pan gaskets, coolant leaks from hoses and water pump.
Common Transmission Issues:
Solenoid failures in electronically controlled transmissions (e.g., 42LE), torque converter shudder, leaks from transmission seals.
Common Electrical Issues:
Faulty power window motors, issues with the automatic climate control head unit, alternator failures, intermittent dashboard warning lights.
Chrysler Brand:
Chrysler positioned the Imperial as its flagship luxury sedan, emphasizing comfort, prestige, and advanced features.
Third Gen Transition:
The manual covers the final years of the third generation (1981-1989), which saw a significant redesign in 1988, incorporating new styling and mechanical updates.
Fourth Gen Introduction:
The fourth generation (1990-1993) was a major redesign, sharing the LH platform with the Chrysler Concorde and Dodge Intrepid. It featured a more aerodynamic profile and a focus on refined driving dynamics.
Production Period:
The Imperial nameplate had several distinct eras. This manual specifically targets the 1988-1993 models, representing the final iterations of the nameplate.
Manufacturing Location:
Likely assembled at Chrysler's Windsor, Ontario, Canada plant, which was a primary assembly location for many Chrysler products of this era.
