👋 Introduction

Market Position:

The 1998 Mitsubishi Montero (often referred to as the second-generation facelift or Pajero in many markets) was a highly capable, body-on-frame SUV positioned as a rugged and versatile option in a segment that was increasingly leaning towards unibody crossovers. It competed with vehicles like the Toyota Land Cruiser Prado, Nissan Pathfinder, Ford Explorer, and Jeep Grand Cherokee, offering superior off-road prowess and durability.

Competitive Analysis:

The Montero distinguished itself with its Super Select II 4WD system (on higher trims), robust chassis, and often more potent V6 engine options compared to some competitors. Its interior, while functional, might have been considered less refined than some rivals, but its off-road capabilities were generally superior. This manual provides the technical backbone for maintaining these strengths.

Key Features:

Full-time 4WD with lockable differentials (Super Select II), independent front suspension for improved on-road comfort, robust rear solid axle for off-road articulation, powerful V6 engine options, available multi-mode automatic transmission, durable construction, and significant cargo capacity. The software format offers instant access and powerful search capabilities crucial for efficient repairs.
