A full car service covers dozens of checks and component replacements designed to keep your vehicle running safely and efficiently. Many drivers are unsure what is actually included in a full car service, which makes it difficult to compare quotes or spot when work is being missed. This complete checklist explains every key area covered.
Engine and Fluids
The engine section is the heart of any full service. A technician will drain and replace the engine oil and fit a new oil filter. Old oil loses its lubricating properties over time and contributes to engine wear if not changed on schedule.
Other fluids checked and topped up include:
- Engine coolant (antifreeze): Checked for level, concentration, and contamination.
- Brake fluid: Tested for moisture content — brake fluid absorbs water over time, which lowers its boiling point and can cause brake fade.
- Power steering fluid: Checked for level and condition on vehicles with hydraulic steering.
- Windscreen washer fluid: Topped up with a screenwash solution appropriate for the season.
Filters
A full service typically includes inspection and replacement of key filters:
- Oil filter: Always replaced at every service alongside fresh engine oil.
- Air filter: Inspected and replaced if blocked. A clogged air filter reduces engine performance and fuel efficiency.
- Cabin / pollen filter: Inspected and replaced if necessary. This filter cleans the air entering the passenger compartment and is especially important for allergy sufferers.
Fuel filters are checked as part of a major or manufacturer service rather than a standard full service, as they typically need replacing less frequently.
Brakes
A full visual inspection of the braking system is carried out, covering:
- Brake pad thickness: Pads are measured to determine remaining life. Most manufacturers recommend replacement when pads reach 2–3 mm.
- Brake disc condition: Discs are checked for scoring, warping, and minimum thickness.
- Brake lines and hoses: Visually inspected for leaks, cracking, or corrosion.
- Handbrake operation: Tested to ensure it holds the vehicle securely on a gradient.
If brake pads or discs need replacing, this will be quoted separately as additional work. Many garages replace pads and discs in pairs (both wheels on the same axle) to maintain even braking performance.
Tyres, Lights, and Electrics
Tyre checks include measuring tread depth across the full width of each tyre (the legal minimum is 1.6 mm), checking tyre pressures, and inspecting sidewalls for damage or cracking. If appropriate, the technician may recommend a tyre rotation.
The electrical check covers:
- All exterior lights (headlights, indicators, brake lights, fog lights, reversing lights)
- Interior lights and dashboard warning lights
- Battery condition and charging voltage
- Windscreen wipers and washers
Wiper blades are often replaced as a chargeable extra if they are found to be smearing or streaking.
Steering, Suspension, and Exhaust
The steering and suspension check is a visual and physical inspection of key components including the steering rack, track rod ends, wheel bearings, shock absorbers, and suspension bushes. The technician will note any play, noise, or wear that could affect handling or safety.
The exhaust system is visually inspected for corrosion, leaks, or loose mountings. An emissions test may also be carried out, particularly relevant for vehicles approaching their MOT date. A healthy exhaust is important both for emissions compliance and for preventing harmful gases from entering the cabin.
At the end of a full service, the garage will stamp your service book (or update your digital service record), provide an invoice detailing all work completed, and advise on any additional work required.
