Variants:
2.2L, 2.5L, 3.0L, 3.3L, 3.8L
Engine Families Implied:
Likely includes Chrysler's own designs (e.g., K-car derived 2.2L/2.5L, later 3.3L/3.8L '3.3/3.8' V6) and potentially Mitsubishi sourced engines (e.g., 3.0L V6, likely the 6G72 family).
Horsepower And Torque:
Detailed specifications available within the manual for each engine variant.
Type:
Fuel injection (likely multi-point or throttle-body injection depending on engine variant and year).
Type:
Naturally aspirated, potentially turbocharged for specific 2.2L variants in earlier model years within the generation's span.
Systems:
Covered in detail, including catalytic converters, EGR, and evaporative emission controls as mandated by regulations of the era.
Type:
Automatic transmissions were standard on the Imperial. Specific models likely include the A604 (4-speed electronic transaxle) for FWD models and potentially a TorqueFlite variant for RWD if any models were RWD during this generation.
Type:
Manual transmissions were generally not offered on the Imperial during this period, particularly on the V6 models.
Control Systems:
Electronic control for automatic transmissions, with diagnostics and troubleshooting procedures for shifting logic and solenoid operation.
Wheelbase:
Approx. 113.5 inches (2883 mm)
Length:
Approx. 208.0 inches (5283 mm)
Width:
Approx. 74.2 inches (1885 mm)
Height:
Approx. 54.0 inches (1372 mm)
Curb Weight:
Approximately 3,600 - 3,800 lbs (1630 - 1725 kg), varying with engine and options.
NHTSA Ratings:
Specific ratings for 1990-1993 models are not readily available in a consolidated format, but vehicles of this era typically had frontal impact protection. The manual will contain specific safety system details.
ABS:
Anti-lock Braking System (ABS) was an available option or standard on higher trims, with detailed diagnostic and repair procedures in the manual.
Airbags:
Driver-side airbag became increasingly standard during this period; passenger airbags were less common. Manual covers airbag system diagnostics and safety precautions.
Seat Belts:
Includes detailed information on seat belt operation, maintenance, and potential adjustments or repairs.
Oil Change:
Typically every 3,000-5,000 miles or 6 months, depending on driving conditions and oil type. Manual will specify exact intervals and oil type.
Tune Up:
Spark plug replacement, filter changes, and inspections at intervals around 30,000-60,000 miles. Manual details specific procedures and components.
Engine Oil:
Viscosity grade (e.g., 5W-30, 10W-30) and API service classification specified by engine type. Manual provides definitive recommendations.
Coolant:
Ethylene glycol-based coolant, likely a conventional green type. Manual specifies type and mixture ratio.
Transmission Fluid:
Specific ATF (Automatic Transmission Fluid) type required for each transmission variant (e.g., ATF+3 or equivalent for later transmissions). Manual details correct type and capacity.
Common Problems:
Typical issues for vehicles of this era might include: aging rubber components (hoses, belts, suspension bushings), power window/lock motor failures, climate control system issues, minor electrical gremlins, and potential transmission control module (TCM) problems in electronically controlled automatics. The manual is invaluable for diagnosing these.
Electrical Components:
Wiring harness integrity, sensor failures, and control module issues are common areas of concern addressed by the detailed wiring diagrams and diagnostic procedures.
Chrysler Legacy:
Chrysler has a long history of producing luxury and executive vehicles, with the Imperial nameplate representing the pinnacle of their offerings for many decades.
Fifth Generation Context:
The 1990-1993 Imperial marked the final iteration of the Imperial nameplate. It was a luxury sedan based on the Chrysler LH platform (though its underpinnings were derived from the Y-body platform shared with other large Chrysler vehicles of the era, like the New Yorker and Dynasty). This generation aimed to offer a blend of American luxury with modern technology for its time.
Manufacturing Location:
North America (likely Detroit, Michigan assembly plants).
