Diesel maintenance notes for this vehicle<\/h2>\n

Maintaining a 3.0L LM2 diesel engine requires attention to specialized service items. Because modern diesel turbochargers and high-pressure fuel systems are complex, adhering to strict fluid change intervals is critical for long-term reliability. Owners should focus on fuel filtration, glow plug health, and Diesel Exhaust Fluid (DEF) management where applicable.<\/p>\n
