⚙️ Engine Specifications

Engine Type:

V8 OHV (Overhead Valve)

Engine Displacement:

Typically 360 cubic inches (5.9L) for the 1989 model year. Some earlier or later variants may have different displacements.

Horsepower Approximate:

Approximately 144-178 hp (varies by specific engine tune and emissions regulations).

Torque Approximate:

Approximately 260-280 lb-ft (varies by specific engine tune).

Fuel Delivery:

Primarily carburetor-based (e.g., Carter, Rochester) for 1989, with potential for early forms of electronic fuel injection on some export or specialized models.

Oil Type:

Typically API SG or SH, SAE 10W-30 or 10W-40. Consult specific manual for exact OEM recommendation.

Coolant Type:

Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Consult specific manual for type and capacity.

🔧 Transmission

Transmission Type:

Typically 3-speed automatic transmission (e.g., Chrysler TF-999, TF-727 for earlier models or heavy-duty applications). Manual transmission options were rare or unavailable for the Grand Wagoneer in these later years.

Optional Transmission:

Manual transmissions were generally not standard or commonly available for the Grand Wagoneer in 1989. The focus was on robust automatic transmissions.

Transmission Fluid:

Typically DEXRON-III (or equivalent) automatic transmission fluid. Consult specific manual for exact specification and capacity.

📐 Dimensions

Approx. 196.3 inches (4986 mm)

Width:

Approx. 74.7 inches (1897 mm)

Height:

Approx. 66.2 inches (1681 mm)

Wheelbase:

Approx. 119 inches (3023 mm)

Curb Weight:

Approx. 4,400 - 4,700 lbs (2000 - 2132 kg), depending on configuration.

🛡️ Safety Features

Crash Test Data:

As a 1989 vehicle, comprehensive modern crash test data (like NHTSA 5-star ratings) is not directly comparable. Safety features of the era focused on passive restraints and structural integrity.

ABS:

Optional Anti-lock Braking System (ABS) may have been available, particularly on later models or as an option.

Seat Belts:

Standard front and rear seat belts. Lap belts may be present in the rear depending on configuration.

💡 Technology Features

Audio System:

Typically an AM/FM radio with cassette player. Higher trims might have upgraded speakers or equalizer options.

Cruise Control:

Available as an option on most models.

Connectivity Features:

Limited by era; primarily mechanical and basic electrical systems. No modern infotainment or driver assistance features.

🔧 Maintenance

Oil Change Interval:

Typically every 3,000-5,000 miles or 3-6 months, depending on driving conditions. Consult manual for exact interval.

Transmission Fluid Change:

Generally recommended every 30,000-60,000 miles. Consult manual for specific interval and fluid type.

Spark Plug Replacement:

Intervals vary; typically 30,000-60,000 miles. Consult manual for specific plug type and gap.

Brake Fluid:

DOT 3 or DOT 4 brake fluid. Consult manual for exact specification and capacity.

Power Steering Fluid:

Typically ATF DEXRON-II/III or specific power steering fluid. Consult manual for exact type.

Common Concerns:

Due to age, common issues can include carburetor tuning, aging rubber hoses and seals, rust (especially in rocker panels and wheel wells), electrical gremlins, and wear on suspension and steering components. Transmission cooling system leaks are also a potential concern.

Woodgrain Trim Care:

The distinctive faux woodgrain side trim requires careful cleaning and occasional waxing to prevent deterioration and peeling.
