Cooling System Function

The water pump is responsible for circulating engine coolant through the cooling system. Correct coolant circulation is essential for controlling engine operating temperature and reducing the risk of overheating.

A replacement water pump can be required when there are symptoms such as coolant leakage, abnormal bearing noise, inadequate coolant circulation or evidence of water-pump failure.

This Aston Martin water pump is suitable for applications including:

• Engine cooling-system repairs
• Water-pump replacement
• Coolant circulation repairs
• Engine restoration
• Preventative maintenance
• Aston Martin specialist workshop repairs
• DB9 V12 restoration
• DBS maintenance
• Vanquish V12 maintenance

Installation should be performed by a qualified technician familiar with Aston Martin V12 cooling systems.

Condition

The exact condition should be confirmed from the individual part and supplied photographs.

For a used water pump, buyers should inspect the pump for signs of:

• Coolant leakage
• Corrosion
• Damaged mounting surfaces
• Pulley or drive damage
• Bearing play
• Previous overheating
• Missing components

If purchasing a used pump, matching the physical component and OEM number is particularly important.

Installation

Before installation, compare the replacement pump with the original component, including the part number, mounting configuration, pulley/drive arrangement and coolant connections.

The cooling system should be properly drained and refilled according to the vehicle manufacturer’s service procedure. After installation, the system should be checked for leaks and correctly bled before the vehicle is returned to normal operation.

Before ordering CD338K168A, provide or verify:

• Aston Martin VIN/chassis number
• Vehicle model
• Model year
• Engine specification
• Existing water-pump part number
• Physical photographs of the original pump
