🔧 Maintenance

Oil Change Interval:

Typically 10,000 miles or 12 months, whichever comes first (refer to manual for exact mileage/time based on driving conditions).

Transmission Fluid Service:

Jaguar generally recommends lifetime fluid for the ZF 6HP26, but periodic fluid and filter changes (e.g., every 60,000-80,000 miles) are advisable for longevity, especially in severe service. Manual will specify factory recommendation.

Air Filter Replacement:

Recommended every 30,000-40,000 miles or as per manual inspection.

Cabin Filter Replacement:

Recommended every 15,000-20,000 miles or annually.

Engine Oil:

Refer to manual for specific viscosity grade (e.g., 5W-30 or 0W-30 synthetic) and API/ACEA specifications.

Coolant:

Jaguar Premium Coolant (or equivalent OAT type) in a 50/50 mix with distilled water.

Brake Fluid:

Air Suspension:

Air spring leaks, compressor failures, and valve block issues can occur with age and mileage.

Aluminum Body:

Corrosion around aluminum panel joints and door sills can be an issue if not properly maintained.

Electrical Gremlins:

As with many luxury vehicles of this era, intermittent electrical faults can manifest due to module or wiring harness issues.

Timing Chain Tensioners:

Early V8 engines (not necessarily this specific generation, but worth noting for the V8 family) had issues with plastic timing chain tensioners. The AJ-V8 Gen III in the X350 is generally considered more robust, but inspection and maintenance are key.
