How to use this schedule
Because many DB9s are now older GTs, cooling system age, water ingress, and battery health deserve just as much attention as engine oil changes.
Every 12 months
- Engine oil and filter service
- Battery and charging-system check
- Coolant level and visible hose inspection
- Brake and tyre inspection
- Check for water ingress and interior dampness
Every 24 months
- Brake fluid replacement
- Chassis inspection including bushes and dampers
- Drain and seal inspection around doors, glass, and boot (trunk)
- Alignment review if tyre wear suggests drift
Every 48 months
- Spark plug and ignition system review
- Cooling system age review and coolant replacement if history is unclear
- Transmission service review for Touchtronic cars
- Drive belt inspection
Before long touring use
- Check cooling performance in traffic
- Inspect tyres for age and flat-spotting
- Confirm battery strength and tender habits
- Look for any emerging brake vibration
Checks, fluids, and inspection notes
Regular checks
- Inspect for condensation or dampness after heavy rain.
- Do not dismiss minor idle roughness on a V12 GT.
- Make sure the gearbox feels smooth and predictable when cold and hot.
Fluid strategy
- Use only handbook- or workshop-manual-approved oil and coolant specifications.
- Brake fluid should be changed on time even on low-mileage examples.
- Transmission fluid history matters on automatic cars.
Inspection notes
- A DB9 that has been parked a lot needs a more skeptical initial inspection.
- Cooling-system history is one of the most valuable things to confirm on an older DB9.
Frequently asked questions
Should coolant work be treated as preventative on a DB9?
Yes. Preventative cooling work is cheaper than dealing with an overheating event.
Is annual servicing enough if the car lives on a tender?
Annual servicing is the baseline, but stored cars also need extra inspection for age-related deterioration.
