Includes detailed, system-specific electrical wiring diagrams.
Oil Change:
Every 3,000-5,000 miles or 3-6 months, depending on driving conditions (refer to manual for specifics).
Air Filter Replacement:
Every 12,000-15,000 miles or annually.
Spark Plug Replacement:
Every 30,000-60,000 miles, depending on plug type (copper vs. platinum).
Timing Belt Replacement:
If equipped with a timing belt (check engine specifics), recommended replacement every 60,000-100,000 miles or 5-7 years.
Engine Oil Type:

Engine Reliability:
Isuzu engines are generally considered robust, but timing belts (if applicable) need timely replacement. Carbureted models can be prone to fuel delivery issues.
Transmission Wear:
Manual transmissions can develop clutch wear. Automatic transmissions can suffer from torque converter issues or valve body problems with age and mileage.
Electrical Corrosion:
Older vehicles can experience corrosion in wiring harnesses, connectors, and grounds, leading to intermittent electrical faults.
Suspension Bushings:
Rubber bushings in the suspension and steering can degrade over time, leading to clunks, poor handling, and uneven tire wear.
Rust And Corrosion:
Common issue for vehicles of this era, particularly in areas with road salt. Frame rails, wheel arches, and rocker panels are susceptible.
