• Checks of all lights, instruments, and electrical components.
• Lubrication of door hinges and locks.
• Tyre rotation and pressure adjustment.
• Battery health check.

3. Major Service (Comprehensive Service)

The major service is the most extensive and is typically required every 24 months or 25,000 miles, though some critical components like the cambelt (timing belt) may have specific mileage or age-based intervals (e.g., 60,000 miles or 5 years for many diesel Shoguns). This service covers everything in a full service, plus additional replacements and in-depth inspections of components that have a longer lifespan but are vital for the vehicle's operation.

• All items from the Full Service.
• Replacement of brake fluid (typically every two years).
• Replacement of coolant (every 3-5 years, depending on type).
• Inspection and possible replacement of transmission fluid (manual and automatic).
• Inspection and possible replacement of differential oils (front and rear).
• Inspection and possible replacement of transfer box oil (critical for the Super Select II 4x4 system).
• Cambelt (timing belt) inspection and replacement if due (a critical and often expensive service item, if neglected can lead to catastrophic engine failure).
• Extensive checks of all rubber components, hoses, and belts for cracks or wear.
• Comprehensive underbody inspection for corrosion, damage, and leaks.

Typical Checks During a Shogun Service

Regardless of the service type, a good mechanic will always follow a meticulous checklist. For a Mitsubishi Shogun, this often includes:

• Engine: Oil and filter, air filter, fuel filter, spark plugs (petrol), drive belts, coolant levels and condition, radiator, hoses.
• Brakes: Pads, discs, calipers, brake fluid level and condition, brake lines, handbrake adjustment.
• Tyres: Tread depth, pressure, condition, wear pattern, spare tyre.
• Steering & Suspension: Ball joints, bushes, shock absorbers, power steering fluid, steering rack.
• Drivetrain (4x4 Specific): Front and rear differential oils, transfer box oil, propeller shafts, universal joints, CV boots.
• Fluids: Engine oil, brake fluid, coolant, power steering fluid, transmission fluid, washer fluid.
• Electrical: Lights (headlights, tail lights, indicators, brake lights), horn, battery health, charging system, warning lights.
• Exhaust: Condition of pipes, silencers, catalysts, mounting points.
• Underbody: Inspection for rust, damage, leaks, and integrity of chassis components.

The Importance of Specialist Knowledge and Parts

Given the Shogun's specific design, particularly its robust 4x4 system, choosing a service centre with experience in such vehicles is highly beneficial. Mechanics familiar with the intricacies of the Super Select II system, the diesel engines, and common wear points will provide a more thorough and effective service. Furthermore, insisting on genuine Mitsubishi parts or high-quality OEM (Original Equipment Manufacturer) equivalent parts is crucial. These parts are designed to meet the precise specifications of your Shogun, ensuring optimal performance and reliability, unlike cheaper, inferior alternatives that may compromise your vehicle's integrity.

DIY Checks vs. Professional Servicing

While some basic checks can and should be performed by the owner, a professional service is indispensable for comprehensive maintenance. Owners can easily check:

• Engine oil level and condition.
• Coolant level.
• Brake fluid level.
• Tyre pressures and tread depth.
• Wiper blade condition and washer fluid level.
• All lights are working.

However, for the in-depth inspections, fluid changes requiring specific tools, and the diagnosis of potential issues that only an experienced eye can spot, professional servicing is non-negotiable. It also ensures that a complete service history is maintained, which is vital for warranty purposes and future resale.

Example Shogun Service Schedule Overview

It's crucial to consult your Shogun's owner's manual for the precise service intervals applicable to your specific model year and engine. However, a general guide might look like this:

Note: Specific mileage and age intervals for critical components like the cambelt (timing belt) and automatic transmission fluid should always be strictly adhered to as per manufacturer guidelines.

Common Shogun-Specific Maintenance Considerations
