Automotive Auxiliary Pump for Land Rover Engine Auxiliary Water Pump OE LR067228 Auto secondary pump cooling system 

Product Description:

Auto auxiliary water pump

OE numbers: LR067228

Applicable vehicle type: For Land Rover

The auxiliary pump, also known as the secondary pump in Chinese, is not a single component but refers to additional pump devices set up to assist the main pump in specific systems or under specific operating conditions, or to achieve independent functions.

Common faults and symptoms:

• Understanding the potential failure signs of the auxiliary water pump can help identify issues promptly:
• Engine overheating (turbocharger cooling auxiliary pump): Failure of the water pump may prevent the turbocharger from dissipating heat effectively, indirectly causing the engine coolant temperature to rise, especially after restarting the engine when it is hot.
• Inadequate heating or slow heating of the cabin (heater circulation auxiliary pump): Insufficient warm air temperature or delayed heat delivery inside the vehicle when the engine is running at low temperatures or idling.
• Coolant leakage: Traces of coolant leakage (such as pink, green, or blue liquid or crystals) may be observed on the water pump housing or seals.
• Unusual noises: Damage to the internal motor or bearings of the water pump may produce humming, friction, or jamming sounds.
• Warning light illumination: The related system (such as the engine management system) may trigger an alarm due to abnormal operation of the water pump.

Regular maintenance: Using coolant that meets the manufacturer's standards and timely replacement is key to extending the lifespan of auxiliary water pumps and other cooling system components. Low-quality coolant or water can easily lead to scale formation and corrosion.
