Specialist JLR engine rebuilds and repairs at our Hedley Avenue workshop in Grays.
Don't Have Reg..?
Range Rover Garage is an independent JLR specialist based in Grays, working exclusively on Range Rover, Land Rover and Jaguar engines. Local owners gain a convenient main dealer alternative, with factory-trained engineers who diagnose, rebuild and replace Ingenium, TDV6, SDV6 and TDV8 engines across Defender, Discovery and Range Rover models.
Our fully equipped workshop sits at Unit 1 Hedley Avenue, RM20 4EL, close to Chafford Hundred and West Thurrock. Owners across the RM16 and RM17 postcode areas and nearby Tilbury can call in, pre-book or arrange collection, and most rebuilds are completed within 7 to 14 working days.
Check Our Opening Hours
Our workshop is open Monday to Friday from 9am to 6pm and Saturday from 8am to 2pm. Walk-ins are welcome, but calling ahead with your registration and symptoms helps us set aside diagnostic time for your vehicle.
Bottom-end knocking, falling oil pressure or heavy oil consumption usually indicate internal wear that only a full Range Rover engine rebuild will resolve.
Engines are stripped, ultrasonically cleaned, machined and rebuilt with genuine OEM parts in our Grays workshop, then pressure-tested and run under load.
Warning lights, misfires, rough idle or limp mode on your Land Rover need accurate fault finding before any parts are ordered or fitted.
Local owners can drop in for same-day diagnostics on most bookings, using dealer-level equipment alongside hands-on testing by JLR-trained engineers.
When repair costs outweigh your Defender's value, we supply and fit tested reconditioned engines matched precisely to its engine code.
Reconditioned units carry six months' warranty, with dealer-level cover of up to 24 months also available.
Having a specialist JLR engine workshop in Grays means local owners avoid long trips to a main dealer. You can walk in, pre-book an appointment or have us collect from home or work across Chafford Hundred, Tilbury and wider Thurrock. Our engineers are factory-trained on Range Rover, Land Rover and Jaguar engine systems, fit genuine or OEM-grade parts tested to manufacturer specifications, and agree an itemised quote with you before any work begins, with direct updates from our team throughout.

Our Services
Alongside rebuilds and replacements, our Grays engineers repair specific engine faults on Range Rover, Range Rover Sport, Evoque, Velar, Vogue, Discovery and Defender models for owners throughout Thurrock.

A metallic rattle for a few seconds on a cold start is one of the most familiar Range Rover common faults, usually caused by chain stretch. We replace chains, guides and tensioners together, helping prevent costly valve damage.

Lost power on the A13, a whistle under acceleration or blue smoke from the exhaust can all signal a failing turbocharger. We check the oil feed, boost hoses and actuator first, so the replacement turbo lasts as it should.

Overheating, coolant loss with no visible leak or a milky deposit under the oil cap can all indicate head gasket failure. We pressure-test the cooling system and inspect the cylinder heads for warping and cracks before repairing the engine.

Many engine faults, including oil leaks, injector problems, sticking EGR valves and failed sensors, can be repaired without a rebuild. Targeted repairs keep your costs proportionate, and every engine is tested thoroughly before it is returned to you.

For higher-mileage Discovery, Freelander and older Range Rover models, a tested second-hand engine can be the most practical way back on the road. We confirm full compatibility first, and every engine swap includes one month's warranty as standard.

Some earlier Land Rover engines use a timing belt that must be renewed at the manufacturer's recommended interval. We carry out scheduled and emergency belt changes, helping you avoid the bent valves and piston damage a snapped belt causes.

Philip Grange
"I dropped my Discovery Sport in on a Saturday morning with an engine warning. Their diagnostics found a faulty oxygen sensor rather than a catalytic converter problem, and they explained everything before quoting."
Gemma Lord
"Being local to Chafford Hundred, I could pop in to see the timing chain work on my Jaguar F-Pace. They showed me the worn parts, explained the itemised quote and called when it was ready."
Craig Harding
"Even though we're only in West Thurrock, collection made sense with both of us working. They picked up the Defender 90 first thing and dropped it back the following week with the warranty paperwork explained."
