LR118241 Electrical Water Pump for Range Rover Evoque & Discovery AJ20P4 2.0T
The LR118241 Electrical Water Pump is used in Jaguar Land Rover vehicles equipped with the AJ20P4 2.0-litre turbocharged petrol engine introduced in 2019. Unlike traditional belt-driven pumps, this unit is an ECU-controlled electric coolant pump that regulates coolant circulation according to engine load and temperature.
During cooling system repairs on the Range Rover Evoque and Land Rover Discovery Sport platforms, technicians frequently identify the Electronic Coolant Pump LR118241 when diagnosing overheating warnings or unstable coolant temperature. Once the internal motor begins to weaken, coolant flow becomes inconsistent, especially during stop-start driving or heavy acceleration.
Workshops sourcing a Jaguar Land Rover AJ20P4 2.0T coolant pump often cross-reference part numbers LR118241, LR127859, LR140742 and LR115260. These OE numbers are associated with the same electronic coolant circulation system used in the Ingenium petrol engine family.
For distributors and engine rebuilders supplying parts for modern Land Rover platforms, maintaining availability of this Range Rover Evoque Water Pump helps address a common service requirement related to cooling system performance.

Common Cooling System Problems Linked to Pump Failure
Technicians investigating Land Rover Discovery Sport overheating electric water pump failure typically observe several warning signs before complete pump failure occurs. Common symptoms include:
- Engine temperature warning message on dashboard
- Coolant circulation reduced at idle
- Heater output fluctuating in cold weather
- Diagnostic fault codes related to coolant pump control
- Intermittent overheating in city driving
Another frequent search from technicians is Range Rover Evoque coolant pump symptoms warning light, which usually indicates declining pump performance rather than thermostat failure.
LR118241 Electric Water Pump Lifespan
Workshop data shows the LR118241 electric water pump lifespan generally ranges between: 80,000 – 120,000 km. Service life depends heavily on coolant maintenance and operating temperature cycles. Factors that shorten pump life include:
- Old coolant with reduced corrosion protection
- Frequent stop-start driving in urban traffic
- High engine operating temperature
- Delayed cooling system maintenance
When replacing the AJ20P4 2.0T Petrol engine electrical water pump LR127859, technicians normally inspect the thermostat housing and coolant hoses to prevent repeat repairs.

FAQ
1. Is LR118241 interchangeable with LR127859 or LR140742?
Yes. The OE numbers LR118241, LR127859 and LR140742 are commonly listed within the same electronic coolant pump system used on the AJ20P4 engine platform.
2. What are the typical symptoms of Range Rover Evoque coolant pump failure?
The dashboard shows a coolant temperature warning or reduced power mode. Some owners report the electric fan running constantly while the engine stays warmer than normal.
3. How long does an LR118241 electric water pump last?
Most units run beyond 120,000 miles when coolant is changed on schedule and the electrical connection stays clean and dry.
4. What vehicles use the LR118241 Electrical Water Pump?
The LR118241 Electrical Water Pump is used in Jaguar Land Rover vehicles equipped with the Ingenium AJ20P4 2.0T petrol engine, including the Range Rover Evoque (2019–) and Land Rover Discovery Sport (2019–).
5. Can a faulty LR118241 electric water pump cause engine overheating?
Yes. When the Electronic Coolant Pump LR118241 stops circulating coolant properly, engine temperature can rise quickly, especially in slow traffic or under heavy load.
6. How long does the LR118241 electric water pump usually last?
In workshop experience, the LR118241 electric water pump lifespan is typically between 80,000 km and 120,000 km, depending on coolant condition and operating temperature cycles.
7. Is LR118241 a mechanical or electric water pump?
The LR118241 Electrical Water Pump is an electronically controlled coolant pump powered by an electric motor and regulated by the vehicle ECU.
8. Does the water pump need programming after installation?
In most cases, the LR118241 coolant pump does not require programming. However, technicians usually perform a diagnostic check to confirm pump operation and clear any stored fault codes.
