ENGINE · EVERY 15,000 MI / 1 YR

Service: engine oil & filter

The core of every Land Rover service. Modern turbo engines and DPFs depend on the exact oil specification, not just the viscosity.

Many specialists halve this interval on high-mileage diesels, short-trip cars and anything that tows.

Parts
  • Engine oil (5W-20 to WSS-M2C925-A (check the cap); ≈7–8.5 L)
  • Oil filter (to suit engine) LR031439
  • Sump plug washer (or sump plug and washer) LR073675
Tools
  • Drain tray
  • Socket set
  • Filter housing socket
  • Torque wrench
  • Diagnostic tool to reset the service indicator

Steps

  1. Warm the engine, park level, and lift or raise the vehicle safely (on air suspension, select the jacking/workshop mode first so it does not move under you).
  2. Remove the engine undertray. Drain the oil and renew the sump plug washer (some engines need a new plug).
  3. Renew the filter: cartridge types unscrew the housing cap; fit the new O-rings supplied and tighten the cap to the torque on it.
  4. Refill with 5W-20 to WSS-M2C925-A (check the cap). Start, check for leaks, then check the level after a few minutes on the dipstick or in the instrument menu (≈7–8.5 L).
  5. Reset the service indicator with the menu or a diagnostic tool, and log the service here.
BODY · EVERY 15,000 MI / 1 YR

Pollen (cabin) filter

A blocked filter weakens the blower and mists the windows.

Parts
  • Pollen filter JKR500010 / LR170345
Tools
  • Trim tools

Steps

  1. Find the filter (behind the glovebox or under the scuttle panel, depending on model).
  2. Note the airflow arrow, fit the new one the same way.
FUEL & AIR · EVERY 30,000 MI / 2 YRS

Air filter element

Turbo engines lose power and economy, and the airflow sensor gets dirty, when the filter blocks.

Bulkhead uses every second service; check your Maintenance Check Sheet for your exact vehicle.

Parts
  • Air filter PHE000112
Tools
  • Screwdrivers / Torx

Steps

  1. Release the airbox lid and lift out the element.
  2. Wipe out the box, check the seal, fit the new element so it seats all round.
  3. Check the intake ducts for splits. Inspect more often in dusty use.
IGNITION · EVERY 60,000 MI / 7 YRS

Spark plugs

Worn plugs cause misfires that can damage the catalytic converters.

Check the plug interval on your Maintenance Check Sheet; Land Rover's varies by engine.

Parts
  • Spark plugs (long-life plugs to suit engine (one per cylinder))
Tools
  • Plug socket
  • Torque wrench
  • Trim tools for coil covers

Steps

  1. Remove the engine covers and the coils one at a time.
  2. Blow dirt out of the plug wells before removing each plug.
  3. Fit the new plugs to the specified torque; don't use anti-seize unless your manual says so.
  4. Refit the coils firmly and clear any misfire codes.
ENGINE · EVERY 15,000 MI / 1 YR

Auxiliary belt & tensioner check

On many of these engines the auxiliary belt drives the water pump and alternator; a snapped belt can be pulled into the timing belt cover.

Parts
  • Auxiliary belt (if cracked)
Tools
  • Torch

Steps

  1. Check the belt for cracks, missing ribs and glazing.
  2. Check the tensioner holds steady with the engine running and the pulleys run quietly.
COOLING · EVERY 10 YRS

Coolant change (10-year)

Land Rover renews the coolant every 10 years regardless of mileage. Check the level and strength every service.

Parts
  • Antifreeze concentrate (OAT antifreeze to Land Rover spec)
  • Hoses & clips (if needed) (replace any soft, swollen or cracked hoses)
Tools
  • Drain tray
  • Garden hose
  • Screwdrivers
  • Hydrometer or refractometer

Steps

  1. Work on a cold engine only. Remove the expansion tank or radiator cap slowly.
  2. Open the radiator drain (or remove the bottom hose) and the cylinder block drain tap or plug. Set the heater to hot.
  3. Flush with clean water until it runs clear. Squeeze every hose: replace any that feel soft, crunchy or swollen.
  4. Check the radiator fins, fan blades and (where fitted) the viscous coupling. A viscous fan should turn with some resistance when the engine is warm.
  5. Refill with a 50% antifreeze mix (OAT antifreeze to Land Rover spec). Fill slowly to avoid air locks; on coil-sprung models use the bleed screw on the thermostat housing or radiator top where fitted.
  6. Run the engine to working temperature with the cap off (or loose), top up as the level drops, refit the cap and check again when cold.
BRAKES · EVERY 15,000 MI / 1 YR

Brakes, tyres & suspension inspection

Heavy vehicles with big wheels wear pads, discs and tyres quickly.

Parts
  • Brake pads (if under 3 mm)
  • Brake discs (if under minimum)
Tools
  • Jack and stands (or a lift)
  • Vernier
  • Torch

Steps

  1. Check pad thickness and disc condition on every wheel (many models also have pad wear sensors).
  2. Check tyres for wear, damage and age; check the spare.
  3. Look for leaks at the dampers, and check ball joints and bushes for play.
  4. Check brake pipes and hoses for corrosion and chafing.
BRAKES · EVERY 3 YRS

Brake fluid change

Land Rover renews brake fluid every 3 years regardless of mileage.

Parts
  • Brake fluid (DOT4 low-viscosity brake fluid to Land Rover spec (ESP/ABS systems))
Tools
  • Pressure bleeder
  • Diagnostic tool (ABS bleed routine on some models)

Steps

  1. Bleed each wheel in the order in your workshop manual.
  2. Some models need an ABS bleed routine run with a diagnostic tool.
  3. Check the pedal is firm before driving.
TRANSMISSION · EVERY 60,000 MI / 5 YRS

Transfer box & locking-diff oil

Land Rover changes the transfer box and rear locking diff oil every 5 years on vehicles that have them.

Parts
  • Transfer box oil (Land Rover-specified fluid)
  • Locking diff oil (if fitted) (Land Rover-specified fluid)
Tools
  • Socket set
  • Oil pump

Steps

  1. Check your vehicle has a two-speed transfer box (a low-range button) and an electronic locking rear diff.
  2. Drain and refill each to its level plug with the specified fluid.
TRANSMISSION · EVERY 60,000 MI / 6 YRS

Automatic gearbox fluid & differentials

Land Rover lists these fluids as long-life (changed at 10 years on many models). Specialists change the automatic gearbox fluid and filter, and the diff oils, sooner on a vehicle that tows or is kept beyond its warranty.

Bulkhead's advisory interval. The official Land Rover interval is longer; check your Maintenance Check Sheet.

Parts
  • ATF (ZF Lifeguard fluid for ZF gearboxes)
  • Gearbox sump pan / filter (to suit gearbox; the sump pan includes the filter on the 8-speed)
  • Differential oil (Land Rover-specified fluid)
Tools
  • Socket set
  • Fluid pump
  • Diagnostic tool (to read fluid temperature)

Steps

  1. The ZF automatics are filled at a set fluid temperature (about 35–45 °C) with the engine running: you need a diagnostic tool to read it.
  2. Renew the sump pan or filter and refill to the level plug as the workshop manual describes.
  3. Drain and refill the front and rear differentials (and the transfer unit/PTU on transverse-engined models).
SUSPENSION · EVERY 15,000 MI / 1 YR

Air suspension check

Air springs perish with age; a leak makes the compressor overwork and fail.

Parts
  • Air spring (if leaking)
Tools
  • Soapy water spray
  • Diagnostic tool

Steps

  1. Park overnight on level ground; note any corner that has dropped.
  2. Spray the air springs (folds at the bottom) and pipe joints with soapy water to find leaks.
  3. Read the suspension codes; listen for the compressor running for long periods.
BRAKES · EVERY 15,000 MI / 1 YR

Electric parking brake check

The electric park brake must hold on a slope; some models use small drum shoes inside the rear discs that need adjusting.

Parts

None

Tools
  • Diagnostic tool

Steps

  1. Check it holds the vehicle on a steep slope.
  2. Models with drum-in-disc shoes: check and adjust them as your manual describes (a diagnostic tool may be needed to set service mode).
  3. Never work on the rear brakes without putting the EPB into service mode first.
BODY & CHASSIS · EVERY 1 YR

Underbody & corrosion check

Subframes, brake pipes and (on the Discovery 3/4 and Sport L320) the steel frame corrode in salty winters.

Parts
  • Cavity wax / underbody protection
Tools
  • Torch
  • Pressure washer

Steps

  1. Wash the underside, then check the subframes, frame rails, brake and fuel pipes, and the rear arches.
  2. Treat any bare metal and re-wax cavities.
SAFETY · EVERY 1 YR

Annual safety inspection

Do this before the MOT and you will rarely fail.

Parts
  • Bulbs & fuses (spares, if needed)
  • 2 × Wiper blades (if worn)
Tools
  • Helper
  • Tyre gauge

Steps

  1. Lights: every light works, including brake lights, indicators, reverse light and number plate light.
  2. Wipers and washers clear the screen. Horn works.
  3. Seat belts latch, retract and are not frayed. Seat mounts are secure.
  4. Exhaust: no blows and the mountings are secure.
  5. Tyres: tread depth, cuts, bulges and age. Check the spare too.
  6. Brakes pull up straight and the handbrake holds on a hill.
SAFETY · EVERY MONTHLY

Monthly walk-round checks

Five minutes a month catches leaks and low levels before they become repairs.

Parts

None

Tools
  • Tyre gauge
  • Torch

Steps

  1. Engine oil on the dipstick between the marks.
  2. Coolant level (check cold), brake and clutch fluid levels, washer fluid.
  3. Tyre pressures (including the spare) and look for cuts.
  4. Look under the vehicle where it has been parked. Note the colour of any drips: brown/black = oil, green/blue/orange = coolant, red = ATF or PAS, clear and slippery = brake fluid.
  5. All lights work.
