Commonly used in modern Porsche thermal management systems, the auxiliary coolant pump assists with coolant circulation during specific operating conditions, including engine shutdown phases, low engine speeds, and demand-controlled cooling strategies. Manufactured to Bosch’s exacting standards, it delivers reliable operation, efficient coolant flow, and long service life.

What This Product Does:

• Circulates coolant through designated rear cooling circuits
• Supports the vehicle’s thermal management system
• Operates independently of engine speed when required
• Helps regulate temperatures of critical vehicle systems
• Maintains coolant flow during specific operating conditions
• Supports efficient heating and cooling system performance

Symptoms Of Wear Or Failure:

• Cooling system warning messages or fault codes
• Reduced coolant circulation efficiency
• Inconsistent cabin heating performance
• Elevated operating temperatures in certain systems
• Electric pump noise, whining, or buzzing sounds
• Coolant leaks around the pump housing
• Thermal management system faults
• Reduced performance of auxiliary cooling functions

Why Replacement Matters:

• Restores efficient coolant flow through auxiliary circuits
• Supports proper operation of the vehicle’s cooling system
• Helps maintain stable operating temperatures
• Improves heating and thermal management performance
• Reduces the risk of overheating-related component stress
• Prevents cooling system fault codes and warning messages
• Supports long-term reliability of engine and ancillary systems
• Maintains OEM-level performance, efficiency, and driving comfort
