Womala Warm water pump JEX000030 for Land Rover

Product Overview

The Auxiliary Water Pump JEX000030 is a genuine OE-grade component engineered for the fuel-fired parking heater system on select for Land Rover vehicles . This 12V electric pump circulates engine coolant through the auxiliary heater and engine circuit, ensuring the pre-heater warms the coolant evenly before engine start-up — making cold starts easier and reducing emissions .Supersession: JEX000032 → JEX000030 

⚠️ Important: This is an auxiliary circulation pump for the fuel-fired heater system — not the main engine water pump. Confirm your vehicle is equipped with the factory parking heater option before ordering.

Signs of Failure

• Parking heater not working – pre-heater fails to warm coolant or start 

• Hard cold starts – engine coolant not pre-warmed as intended

• No coolant circulation – pump not operating during heater cycle

• Increased emissions – incomplete pre-heating affecting cold-start emissions 

💡 A faulty auxiliary pump prevents the parking heater from circulating heated coolant, which can lead to difficult cold starts and increased emissions .
