Engine Options For 1989 W463:
While the W463 generation officially launched for 1990 MY, the 1989 model year typically refers to late W460 models carrying over or early production of the W463. The W463 generation offered a range of engines including: 2.3L I4 (M102), 2.6L I6 (M103), 3.0L I6 Diesel (OM602), 2.5L I5 Diesel (OM602), 3.0L Turbo Diesel (OM603), 5.0L V8 (M117). Specific engine for a 1989 W463 would depend on the exact market and variant, but common early W463 engines included the M102 and M103 gasoline, and OM602 diesel.
Typical Horsepower Range:
Ranges from approximately 90 hp (naturally aspirated diesel) to 220 hp (V8 gasoline) depending on the specific engine installed in the W463 platform.
Typical Torque Range:
Ranges from approximately 115 lb-ft (diesel) to 250 lb-ft (V8 gasoline) depending on the specific engine.
Fuel Delivery:
Typically Bosch KE-Jetronic (fuel injection) for gasoline engines, rotary injection pump for diesel engines.
Transmission Options:
Likely equipped with a 4-speed automatic transmission (e.g., 722.4) or a 5-speed manual transmission for gasoline models. Diesel models often featured 4-speed automatics or 5-speed manuals.
Optional Transmission:
Availability of a 5-speed automatic (e.g., 722.6) may have started appearing in later W463 models, but less common for a 1989 example.
Transfer Case:
Selectable 4WD system with locking differentials (center, rear, and sometimes front) for exceptional off-road capability.
Body Styles:
Available in various body styles including short-wheelbase (2-door), long-wheelbase (3-door or 5-door wagon), and convertible (soft top or hardtop).
Ground Clearance:
Significantly high ground clearance, typically over 8 inches, for off-road capability.
Curb Weight:
Varies significantly by engine and body style, generally ranging from approximately 4,000 to 5,000+ lbs.
Crash Test Data:
Specific crash test data for 1989 models may be limited or vary by region. The W463 was designed with robustness in mind, but lacked many modern safety features.
Active Safety Systems:
ABS (Anti-lock Braking System) became available on some W463 models around this time, but was not standard on all variants.
Passive Safety Features:
Seat belts, reinforced chassis, durable body construction.
Audio System:
Basic AM/FM radio and cassette player, often with a modest number of speakers.
Navigation:
No factory navigation system available for this model year.
Advanced Features:
Limited driver assistance features. ABS may be present on some models. Cruise control is a convenience feature.
Connectivity Options:
No modern connectivity features such as Bluetooth or USB ports.
Oil Change Interval:
Typically every 5,000 to 7,500 miles or 6-12 months, depending on driving conditions and engine type. Consult manual for specific engine recommendations.
Transmission Fluid Change:
Automatic transmission fluid and filter changes recommended every 30,000 to 60,000 miles. Manual transmission fluid checks at intervals.
Engine Oil Type:
API SF/SG classification, viscosity grade typically 10W-30 or 10W-40 for gasoline engines; 15W-40 or 10W-30 for diesel engines. Always refer to manual for exact specification.
Coolant Type:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Mercedes-specific coolant (e.g., G48) is recommended.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Common Wear Items:
Rust and corrosion (especially on body panels and chassis), aging rubber hoses and seals, potential for vacuum leaks in older systems, transfer case and differential seal leaks, injector pump issues on diesel models.
Electrical Quirks:
Older electrical systems can be prone to gremlins, particularly related to wiring harnesses and connector corrosion. Window regulators and central locking mechanisms can be points of failure.
Mercedes Benz Off Road Legacy:
The G-Class, originating from the W460 series, was developed in collaboration with Steyr-Daimler-Puch in Austria, designed for military and civilian off-road use.
W463 Introduction:
The W463 marked a significant evolution from the W460, featuring more comfortable interior amenities, independent front suspension (on some models), and a more refined exterior, while retaining its core off-road prowess.
