Range Rover Engine Overheating – Causes, Symptoms, Diagnosis & Professional Repair Guide
Range Rover Engine Overheating – Common Causes, Warning Signs & Expert Repair
A Range Rover engine overheating issue is one of the most serious problems that can affect your luxury SUV. Modern Range Rover engines generate significant heat and rely on an advanced cooling system to maintain the correct operating temperature. If any component in the cooling system fails, the engine temperature can rise rapidly, leading to severe mechanical damage.
Ignoring an overheating engine may result in a blown head gasket, warped cylinder heads, damaged pistons, or even complete engine failure. Whether the issue is caused by a coolant leak, faulty radiator, water pump failure, or thermostat malfunction, immediate diagnosis is essential.
At GT Auto Centre Dubai, our certified Range Rover technicians use advanced diagnostic equipment to identify the exact cause of overheating and perform manufacturer-approved repairs using OEM-quality parts.
Why Your Range Rover Engine Overheats
The cooling system regulates engine temperature by circulating coolant through the engine, radiator, thermostat, water pump, and cooling fans. If any of these components fail, heat cannot dissipate effectively, causing the engine to overheat.
Common Causes of Range Rover Engine Overheating
1. Coolant Leak
- Range Rover coolant leak
- Range Rover coolant loss
- Range Rover coolant repair
- Coolant reservoir leak
- Engine coolant leak
Coolant leaks are the leading cause of engine overheating. Leaks can develop in hoses, radiators, expansion tanks, water pumps, or coolant pipes, reducing coolant levels and preventing efficient heat transfer.
How We Fix It
- Pressure-test the cooling system
- Locate the exact leak source
- Replace damaged hoses, pipes, or reservoirs
- Refill with OEM-approved coolant
- Bleed the cooling system and verify operation
2. Faulty Water Pump
The water pump circulates coolant throughout the engine. A worn impeller, leaking seal, or failed bearing can stop coolant flow, resulting in overheating.
How We Fix It
- Inspect the pump for leaks and bearing play
- Replace the water pump with an OEM-quality unit
- Install new seals and coolant
- Test coolant circulation after installation
3. Thermostat Failure
A thermostat stuck closed prevents coolant from reaching the radiator, causing engine temperatures to rise quickly.
How We Fix It
- Test thermostat opening temperature
- Replace the thermostat and housing
- Install new seals
- Refill and bleed the cooling system
4. Damaged Radiator
A clogged, leaking, or damaged radiator cannot dissipate engine heat effectively.
How We Fix It
- Inspect radiator fins and core
- Repair or replace the radiator
- Flush contaminated coolant
- Pressure-test the system after repair
5. Cooling Fan Failure
Electric cooling fans provide airflow when driving slowly or idling. If they fail, engine temperatures rise rapidly.
How We Fix It
- Scan the fan control module
- Test fan motors and relays
- Replace faulty fans or electrical components
- Verify automatic fan operation
6. Blocked Cooling System
Old coolant can create sludge that blocks coolant passages.
How We Fix It
- Perform a complete cooling system flush
- Remove contaminated coolant
- Clean internal passages
- Refill with manufacturer-approved coolant
7. Head Gasket Failure
A damaged head gasket allows coolant to enter the combustion chamber or engine oil, causing severe overheating.
How We Fix It
- Perform compression and leak-down tests
- Inspect cylinder head condition
- Replace the head gasket
- Machine cylinder heads if necessary
- Reassemble with new OEM gaskets and bolts
8. Failed Coolant Temperature Sensor
- Range Rover Engine temperature sensor
- Range Rover Coolant temperature sensor replacement
- Range Rover Engine warning light
Incorrect sensor readings can prevent cooling fans from operating correctly.
How We Fix It
- Scan ECU fault codes
- Test sensor resistance
- Replace faulty sensors
- Reset system and verify operation
Warning Signs of Engine Overheating
If you notice any of the following symptoms, stop driving and have your vehicle inspected immediately:
- Engine temperature gauge in the red zone
- Coolant warning light
- Steam from the bonnet
- Coolant leaking under the vehicle
- Sweet smell from the engine bay
- Reduced engine performance
- Engine misfire
- Heater blowing cold air
- High engine temperature warning
- Loss of coolant without visible leaks
Risks of Ignoring Engine Overheating

Frequently Asked Questions
Why is my Range Rover engine overheating?
The most common causes are coolant leaks, radiator failure, thermostat problems, water pump failure, blocked cooling systems, cooling fan faults, or a blown head gasket.
Can I drive my Range Rover if it's overheating?
No. Driving an overheating engine can cause catastrophic engine damage, including a blown head gasket, warped cylinder head, or engine seizure. Stop the vehicle safely and have it inspected immediately.
What should I do if my Range Rover overheats?
Turn off the air conditioning, safely pull over, switch off the engine, and allow it to cool completely. Do not open the coolant reservoir while the engine is hot. Arrange for professional diagnosis and repair.
How much does it cost to repair a Range Rover overheating issue?
The repair cost depends on the root cause. Replacing a thermostat or hose is generally less expensive than repairing a radiator, water pump, or head gasket. A full inspection is required for an accurate estimate.
How do technicians diagnose engine overheating?
Technicians use computer diagnostics, pressure testing, UV dye leak detection, thermostat testing, cooling fan inspection, coolant analysis, and compression testing to identify the exact cause of overheating.
How often should the cooling system be serviced?
The cooling system should be inspected during every major service and the coolant replaced according to the manufacturer's maintenance schedule to ensure reliable performance.
