How much does a Range Rover Sport 3.0 SC V6 engine replacement cost in the UK?

A reconditioned AJ126 engine typically costs £4,500–£7,500 supply only. Fitting adds £1,100–£1,900. Use our calculator for a figure specific to your vehicle.

Is the Range Rover Sport 3.0 SC V6 engine reliable?

The AJ126 supercharged V6 is rated ★★★☆☆. It offers a rewarding driving experience but has well-documented issues: water pump and cooling system failures, timing chain tensioner wear (especially pre-2015), and supercharger coupler wear. Cooling system maintenance is the key to longevity.

What are the common problems with the Range Rover Sport 3.0 SC V6?

Water pump failure, coolant crossover pipe leaks, timing chain tensioner wear (pre-2015 units), and supercharger coupler wear are the most common issues. None typically lead to full engine replacement if caught early — preventative cooling system maintenance is the priority.

Is it worth replacing a Range Rover Sport 3.0 SC V6 engine, or should I scrap the car?

Against a £15,000–£25,000 Range Rover Sport 3.0 SC V6, a £5,500 recon engine is a manageable 22–37% of the vehicle's value — worth it for a well-maintained example. Given the Range Rover Sport's strong retained values, replacement is usually viable. Scrap only if the vehicle has suffered catastrophic damage well beyond the engine.

How do I find my Range Rover Sport's engine code?

For the 3.0 SC V6, the engine code is AJ126 — it's on the VIN plate and vehicle documentation. The 3.0 SC badge signifies the 3.0-litre supercharged V6. If you're unsure, tell us your registration date and we'll confirm it for free.

Can I repair the AJ126's water pump, or does it need a new engine?

Yes — the water pump is a straightforward repair costing £600–£1,200. The AJ126's water pump and coolant crossover pipes are the most common service items on this engine; replacing them as a preventative measure at 60,000 miles is strongly recommended.

Buying This Range Rover Sport 3.0 SC V6? Check These First

Buy If

Full Land Rover service history with documented oil-change intervals
Water pump and crossover pipes replaced as a preventative measure
Post-2015 build with the revised timing chain tensioners
Evidence of regular motorway driving (the supercharged V6 benefits from regular use)

Avoid If

Pre-2015 unit with no timing chain history or cold-start rattle
Service history shows repeated coolant top-ups with no diagnosis
No record of water pump replacement on higher-mileage examples (60k+)
Engine warning light present with no diagnosis documentation

Closing Verdict

The AJ126 supercharged V6 offers a rewarding driving experience in the Range Rover Sport, but it's a more complex engine than the diesel alternatives. Cooling system maintenance and timing chain tensioner health (especially pre-2015) are the keys to longevity. Buy on service history and proof of preventative cooling system work. If you're replacing, a reconditioned unit with a 12-month warranty is the sweet spot.

Buying Checklist

Before you buy a used Land Rover Range Rover Sport 3.0 SC V6 (or before you commit to an engine replacement), check these:

Cold Start — Listen for any rattle on startup (timing chain tensioner wear — especially pre-2015)

Service History — Including which engine era (AJ126 is the only 3.0 SC V6 — verify this before purchase)

Coolant Level — Is the coolant low with no visible leak? Potential water pump or crossover pipe issue

Supercharger Noise — Any rattle from the front of the engine at idle? Supercharger coupler wear indicator

Oil Leaks — Check the valley between cylinder banks for oil pooling (common on higher-mileage units)

Oil Consumption — Does it use more than 1L per 5,000 miles? If so, investigate

Engine Warning Light — Have codes been read? Any unresolved cooling, timing, or fuelling issues?

MOT History — Check for emissions-related failures; the supercharged V6 should pass easily if well-maintained
