Cooling systems on Range Rovers are pushed to their limits every summer. Plastic coolant crossover pipes on the 5.0 V8, thermostat housings on the TDV6 and auxiliary water pumps on the Ingenium engines are all known wear items, and a small leak can become a warped cylinder head within minutes if it is ignored.
We pressure-test the entire system, inspect every hose and pipe with a borescope, and check for combustion gases in the coolant before diagnosing. Repairs use genuine or upgraded aluminium replacement parts where available, and we finish with a vacuum fill so there are no air pockets.
Cooling System & Overheating on the Range Rover Sport
The Range Rover Sport is driven harder than any other Land Rover, and it shows. Supercharger bearings, brake wear and air suspension on the SVR and V8 models are our daily work, alongside the diesel V6 family's timing chains.
Engines we cover on this model: 3.0 TDV6/SDV6, 5.0 V8 Supercharged, 3.0 Ingenium P400, SVR 5.0. Production 2005 – present (L320, L494, L461). Faults we see most often on the Range Rover Sport include supercharger nose bearing whine on 5.0 v8, front air strut and valve block leaks, brake disc warping under hard use, and each is diagnosed with the model-specific procedure before any parts are recommended.

How we work
Every job begins with a proper diagnosis on the lift and on Land Rover's diagnostic platform. You receive a written report, photos and a fixed price on WhatsApp before any work begins. Genuine or OE-equivalent parts are used, every repair carries a written warranty, and the vehicle is road tested before handover.
Frequently asked questions
Is overheating serious on a Range Rover?
Very. Aluminium engines tolerate very little overheating before the cylinder head distorts. Stop the vehicle and call us on WhatsApp for recovery.
What coolant do you use?
Genuine Land Rover long-life coolant mixed to the correct ratio. Mixing coolant types can cause corrosion and gelling.
How often should the coolant be changed?
Every five years or 150,000 km, or sooner if the system has been opened for a repair.
