The Mitsubishi Montero Sport, also known as the Mitsubishi Challenger in some markets, is a mid-size sport utility vehicle (SUV) produced by Mitsubishi Motors from 1996 to 2023. The second generation of the Montero Sport, which spanned from 2003 to 2008, is the subject of this service repair manual. This generation built upon its predecessor's robust frame and powerful engine options, solidifying its reputation for off-road capability and durability. The 2003 Montero Sport offered a choice of two engine options: a 3.0-liter V6 or a 3.5-liter V6, both coupled with a 4-speed automatic transmission. The vehicle was available in various trims, ranging from basic workhorse models to luxurious, well-equipped versions. Notably, it retained the well-regarded Super Select 4WD system that offered multiple drive modes for optimal traction on various terrains. The 2003 Montero Sport was praised for its rugged build, spacious interior, and exceptional off-road competence. Its ladder frame construction provided a robust platform, capable of enduring demanding conditions. The vehicle's high ground clearance, generous suspension travel, and powerful engines allowed it to tackle challenging terrain with ease. However, the 2003 model year also witnessed some criticisms, including its relatively dated interior, somewhat thirsty fuel economy, and a suspension that could feel somewhat harsh on paved roads. Nevertheless, the Montero Sport maintained its reputation as a dependable and capable SUV, suitable for both daily commuting and adventurous excursions. This service repair manual serves as a comprehensive guide for owners and mechanics seeking to maintain and repair their 2003 Montero Sport, offering detailed instructions and diagrams to address a wide range of mechanical and electrical issues.
