Curb Weight Range:
Approximately 2,800 - 3,300 lbs (1,270 - 1,500 kg), depending on engine, drivetrain, and trim.
Oil Change Interval:
Typically every 3,000-5,000 miles or 3-6 months, depending on driving conditions and oil type used (consult manual for specific recommendations).
Spark Plug Replacement:
Intervals vary by plug type, but typically around 30,000 miles for standard plugs, potentially longer for platinum or iridium (consult manual).
Timing Belt Replacement:
Crucial for 4G63 engines (interference design). Typically recommended every 60,000-90,000 miles or 5-7 years. The manual will specify the exact interval and procedure.
Engine Oil Type:
API SG or SH rated, SAE 5W-30 or 10W-30 (check manual for exact viscosity and capacity).

Ethylene glycol-based antifreeze mixed with distilled water (typically 50/50 ratio). Consult manual for specific capacity.
Automatic Transmission Fluid:
Mitsubishi ATF SP-II or equivalent (check manual for exact specification and capacity).
Common Wear Items:
Ignition components (plugs, wires, distributor cap/rotor), fuel injectors, oxygen sensors, catalytic converter, exhaust system, suspension bushings, CV joints, and wheel bearings can be common wear items due to age.
Specific Galant Issues Era:
Some reports of oil leaks from gaskets and seals, potential issues with automatic transmission solenoids or valve bodies, and occasional electrical gremlins common in vehicles of this age.
Mitsubishi Reputation Era:
Mitsubishi was establishing itself in global markets, known for reliable engines and sometimes performance-oriented variants (like the later Lancer Evolution, though the Galant predates this).
Galant Lineage:
The Galant has a long history dating back to the 1960s, evolving through various sizes and styles. The 1990 model represents a significant shift in design and technology from earlier generations.
