Range Rover 5.0 Supercharged Engine Replacement Cost: AJ133 Buyer's Guide

Range Rover 5.0 Supercharged Engine Replacement Cost: AJ133 Buyer's Guide
26 August 2026

Facing an engine failure on a 5.0L Supercharged Range Rover Sport, Autobiography, or HSE is an incredibly stressful experience. Because the Jaguar Land Rover AJ133 engine is a complex piece of aluminum machinery, replacement costs can vary drastically depending on where you source the motor and who installs it.

In this guide, we break down the real-world Range Rover 5.0 supercharged engine replacement cost, labor expectations, and how choosing a premium remanufactured crate engine from Rover Parts Depo saves you thousands over dealership prices. 

How Much Does It Cost to Replace a Range Rover 5.0 Engine?

When dealing with an AJ133 engine failure, your two primary paths are a Land Rover franchise dealership or a precision independent engine builder like us at Rover Parts Depo. The price gap between these two options is substantial.

Dealership vs. Remanufactured Land Rover Jaguar Engine Costs

If you tow your vehicle to a franchise dealer, a brand-new factory OEM replacement engine block typically costs over $21,500 to $23,800 in parts alone. Once dealership labor rates are applied, the final invoice often climbs past $30,000.

By choosing a precision-remanufactured, zero-mile Range Rover Replacement Engine from Rover Parts Depo, you can drastically cut those costs while getting an engine that fixes known factory flaws:

Crucial Parts to Replace "While You Are In There"

When swapping out an AJ133 engine, you shouldn't just swap the block. Independent mechanics should replace failure-prone peripheral cooling items while the engine is out of the chassis. We recommend installing:

  • Upgraded Metal Cooling Pipes: Ensure your mechanic uses the updated 2025 JLR OEM Aluminum Cooling Pipes (LR186859 & LR186917) instead of brittle plastic versions to eliminate overheating risks forever.
  • Premium Break-In Oil: Always use high-quality break-in oil for the initial startup cycle. Running specialized oil during the first critical running phase ensures the piston rings seat perfectly against the cylinder walls and protects your new internal bearings from premature wear. We highly recommend adding Motul 10W-40 Mineral Based Break-In Oil to your order to protect your new investment from the very first turnkey.

How to Identify Your Range Rover 5.0L Engine Number

Before ordering a replacement block, you must verify your exact engine configuration. For the JLR AJ133 family, the engine identification number and code stamp (typically 508PS for supercharged models) can be found in two primary locations:

  • Engine Block Stamp: Etched directly into the driver-side rear of the engine block cylinder bank, near the bellhousing alignment dowel.
  • Barcoded Factory Sticker: Located on the front plastic timing chain cover (though this is often missing or unreadable on older, high-mileage vehicles).

The Easiest Method: If you cannot find or read these physical stamps, you can simply use your vehicle's VIN (Vehicle Identification Number). If you need help verifying your exact model or want to get an accurate price right away, simply head over to our Get Fast Engine Quote form. Fill out your details, and our specialists will decode your VIN and confirm your exact engine match within one business day.
