Fuel Requirement:
Unleaded Gasoline (87 octane typically recommended, but check manual for specific variants).
Coolant Type:
Ethylene Glycol based coolant (typically a 50/50 mix with distilled water).
Ignition Timing:
Refer to manual for specific base timing and electronic timing advance specifications. Adjustable via ECU or specific sensors.
Transmission Type Standard:
5-speed Manual Transmission
Transmission Type Optional:
4-speed Automatic Transmission with Lock-up Torque Converter
Automatic Features:
Sport/Economy modes (on some models), electronic control for shift points.
Manual Transmission Fluid:
API GL-4, SAE 75W-90 or 80W-90 gear oil (verify exact spec in manual).
Automatic Transmission Fluid:
Mitsubishi Genuine ATF SP-II or equivalent (e.g., Dexron II/III compatible fluids, but verify with manual).
NHTSA Ratings:
Specific NHTSA ratings for this era are generally unavailable or not comparable to modern standards. Focus on structural integrity and occupant protection features.
ABS:
Anti-lock Braking System (ABS) was available as an option on many models, particularly with the V6 engine.
Airbags:
Driver-side airbag became increasingly common and standard by the early 1990s. Passenger airbag was a rarer option.
Seatbelts:
Three-point inertia-reel seatbelts for front occupants, two-point lap belts for rear occupants.
Headlights:
Halogen headlights, typically composite units.
Oil Change Interval:
Typically 3,000-5,000 miles or 3-6 months, whichever comes first. Refer to manual for specific intervals based on driving conditions.
Timing Belt Replacement:
Crucial: 4G63 engines are interference engines. Replacement typically recommended every 60,000-90,000 miles or 5-7 years. Consult manual for precise interval and procedure.
Spark Plug Replacement:
Approx. 30,000-60,000 miles, depending on plug type (copper vs. platinum).
Engine Oil Spec:

Engine Mounts:
Engine mounts can degrade over time, leading to increased vibration and noise.
Automatic Transmission:
Some transmissions may experience rough shifting or delayed engagement, potentially due to solenoid issues or low fluid levels/quality.
Suspension Components:
Worn ball joints, tie rod ends, and control arm bushings are common wear items leading to steering looseness and clunks.
Rust Corrosion:
As with many vehicles of this era, rust can be an issue, particularly in areas with harsh winters or coastal environments. Check wheel wells, rocker panels, and undercarriage.
Electrical Connections:
Corroded grounds or frayed wiring can lead to intermittent electrical issues in various systems.
Mitsubishi Legacy:
Mitsubishi, a Japanese manufacturer with a long history in automotive production, known for engineering prowess and distinctive designs (e.g., Lancer Evolution lineage, although the Galant is a mainstream sedan).
E30 Generation:
The E30/E33A generation marked a significant shift in styling and technology for the Galant, moving towards more aerodynamic and modern design language. It was available in various trim levels and body styles, including sedan and hatchback (later discontinued).
Manufacturing Locations:
Primarily manufactured in Japan. Some models may have been assembled in other regions under license or joint ventures.
Market Reception:
The Galant enjoyed moderate sales success during this period, valued for its comfortable ride, good feature set for the price, and often reliable powertrains.
