Variant History

Range Rover 5.0 SC Engine History & Specs at a Glance

When the 5.0 SC variant launched, it marked the introduction of the all-aluminium AJ133 supercharged V8, replacing the older 4.2L unit and delivering a massive leap in performance and refinement for the flagship Range Rover.

2010
AJ133 (5.0L Supercharged V8), 510hp, introduced in the late L322 generation, featuring a Roots-type supercharger and direct injection.
2013
Carried over to the all-new L405 generation with revised engine mounts, updated ECU mapping, and improved thermal management for the supercharger.
2018
Minor calibration updates to meet stricter WLTP emissions standards while maintaining the 510hp output across the L405 lifecycle.

Every engine fitted to the Range Rover 5.0 SC is covered below, with UK rebuilt pricing and known failure points.

Common failure points and repair options

Timing Chain & Tensioner Wear

Affected: Range Rover 5.0 SC (AJ133, 2010-2022)
Typical failure mileage: 60,000-120,000 miles

Root cause

Early hydraulic tensioners can wear prematurely, leading to chain stretch and a distinct rattling noise on cold starts, which can cause catastrophic internal damage if ignored.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative (Chain Kit & Tensioner Replacement)	£3,500-£5,500	£2,500-£4,500
Full Replacement - rebuilt/reconditioned engine	£12,000-£16,000	£8,000-£12,000 [EM-QUOTE]

Our recommendation

For the Range Rover 5.0 SC, preventative replacement of the coolant crossover pipes and early inspection of the timing chain tensioners is highly cost-effective. However, if you are experiencing timing chain rattle or have suffered catastrophic internal failure, a reconditioned AJ133 engine with upgraded tensioners and cooling components is the safest long-term solution to preserve performance and value.

Coolant Crossover Pipe Leaks

Affected: Range Rover 5.0 SC (AJ133, 2010-2022)
Typical failure mileage: 60,000-120,000 miles

Root cause

The plastic coolant crossover pipes located in the "hot-vee" of the V8 degrade over time due to extreme thermal cycling, leading to coolant loss and potential overheating.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative (Coolant Pipe & Gasket Replacement)	£1,500-£2,500	£800-£1,500
Full Replacement - rebuilt/reconditioned engine	£12,000-£16,000	£8,000-£12,000 [EM-QUOTE]
