The 1987 Mitsubishi Pajero is a compact-to-midsize, body-on-frame SUV from the first-generation (original) Pajero lineup, designed for true off-road capability with everyday usability. It’s ideal for buyers who want an old-school 4x4 for trails, overlanding builds, rural driving, or a classic SUV that’s easy to wrench on. In its era, the Pajero competed with other rugged 4WDs by offering strong low-range performance, simple mechanicals, and durable running gear. Today it’s valued for its toughness and character, with reliability heavily dependent on maintenance history and rust condition.

1) First-generation body-on-frame 4x4 platform with a tough truck-style chassis and available low-range transfer case for serious off-road driving. 2) Engine options commonly included a 2.6L inline-four gasoline (often known as the 4G54 in many markets), plus 2.3L diesel and 2.5L turbo-diesel variants depending on region and trim. 3) Available manual and automatic transmissions, with many models featuring traditional part-time 4WD operation suited for mixed pavement and dirt use. 4) Practical, upright SUV packaging with good visibility, useful cargo space, and a simple interior that’s easy to maintain or restore. 5) Classic, utilitarian suspension and driveline components that respond well to preventative maintenance and are popular for modification (tires, suspension refresh, gearing, and recovery equipment).

Searches for “1987 Mitsubishi Pajero problems,” “1987 Mitsubishi Pajero reliability,” and “1987 Mitsubishi Pajero common issues” often point to age-related wear more than a single fatal flaw. Here are common complaints owners report: 1) Cooling system and overheating issues: Radiators can clog with age, fan clutches weaken, thermostats stick, and old hoses split. Overheating risk increases around 120,000–180,000 miles on neglected vehicles, and repeated overheating can lead to head gasket trouble. 2) Rust and corrosion: Rust is a major reliability factor, especially on frames, floors, rear wheel arches, rocker panels, and body mounts. Coastal or salted-road trucks can develop structural rust that’s more serious than typical cosmetic corrosion. 3) Oil leaks and gasket seepage: Valve cover gaskets, front/rear main seals, and oil pan gaskets commonly weep on higher-mileage examples (often past 100,000 miles). Diesel versions may also show vacuum line issues that affect drivability and accessories. 4) Front-end and steering wear: Ball joints, tie rod ends, steering linkages, and wheel bearings can wear, causing looseness, wandering, or vibrations—often noticeable from 80,000–150,000 miles depending on off-road use and maintenance frequency.
