Engine Code Typical:
4JX1 (3.0L Diesel), C22NE (2.2L Petrol - RHD markets), G22E (2.2L Petrol - LHD markets)
Engine Displacement Petrol:
2.2 Liters (2184 cc)
Engine Displacement Diesel:
3.0 Liters (2999 cc)
Horsepower Petrol Approx:
125-135 PS (depending on market and specific tuning)

Engine Oil Change:
Typically every 5,000-7,500 miles (8,000-12,000 km) or 6-12 months, depending on driving conditions.
Air Filter Replacement:
Every 15,000-30,000 miles (24,000-48,000 km) or annually.
Spark Plug Replacement:
Every 30,000-60,000 miles (48,000-96,000 km) for standard plugs, longer for iridium/platinum.
Timing Belt Replacement:
For petrol engines: typically 60,000-100,000 miles (96,000-160,000 km) or 5-7 years. For diesel (chain driven): generally no scheduled replacement.
Engine Oil Viscosity:
API SG or SH, SAE 10W-30 or 10W-40 (check owner's manual for exact recommendation based on temperature).
Coolant Type:

Diesel Engine Concerns:
4JX1 engine can be sensitive to fuel quality and can experience issues with the injector pump and oil cooler seals if not maintained properly.
Suspension Wear:
Common for older SUVs; ball joints, tie rod ends, and bushings can wear out causing steering and suspension noise.
Body Rust:
As with many vehicles of this era, rust can be an issue in areas prone to road salt and moisture.
