Body Style:
Full-size Sedan
Curb Weight Range:
Approximately 3,800 - 4,200 lbs (varies by engine and options)
Gvw Range:
Gross Vehicle Weight Rating will be specified in the manual and varies by configuration, generally around 5,000-5,500 lbs.
Safety Features General:
Likely equipped with standard safety features for its era, including seat belts, and potentially airbags in later models. ABS is mentioned as a covered system.
Braking System:
Power-assisted brakes, Anti-lock Braking System (ABS) available/standard in later years.
Restraint Systems:
Front seat belts, potential for driver-side airbag in later models (1990 onwards).
Audio System:
Basic AM/FM radio, cassette player, optional CD player in later models. Speaker configurations will vary.
Cruise Control:
Electronically controlled cruise control typically standard or optional.
OBD Ii Compliance:
Models from 1996 onwards are OBD-II compliant. Older models use EEC-IV diagnostic systems. The manual will cover diagnostics for both.
Oil Change Interval:
Typically 3,000-5,000 miles or 3-6 months, depending on oil type and driving conditions. Manual will specify.
General Maintenance Schedule:
The manual will detail comprehensive service intervals for all fluid changes, filter replacements, inspections, and component checks.
Engine Oil Spec:
Likely 5W-30 or 5W-40 API SG or higher, depending on engine. Manual will provide exact specification.
Transmission Fluid Spec:
Likely MERCON or MERCON V for automatic transmissions. Manual will specify.
Coolant Spec:
Likely a conventional green ethylene glycol-based coolant. Manual will specify type and capacity.
Power Steering Fluid:
Likely ATF Dexron-II or equivalent. Manual will confirm.
Common Wear Items:
Suspension components (ball joints, tie rods, bushings), exhaust systems, cooling system components (radiator, hoses), ignition system components, transmission seals.
Engine Specific Concerns:
4.6L engines (if equipped with Pi heads later in the range) are generally robust; older 5.0L/5.8L engines can be prone to oil leaks and valve guide wear. Manual will cover diagnostics for these.
