VEMO Engine Auxiliary Water Pump

The VEMO Engine Auxiliary Water Pump (also called an auxiliary coolant pump, additional water pump or secondary circulation pump) is an electric pump. It circulates coolant in the engine cooling and heating circuit independently of the main mechanical water pump. It helps maintain steady coolant flow when the engine is off or at low speed. This supports cabin heater performance, turbocharger cooling after shut-down, and stable thermal management.

Key Features:

• Electrically driven design that supplies coolant flow on demand
• Supports cabin heating, turbocharger after-run cooling, and auxiliary cooling circuits
• Made to meet or exceed original equipment specifications for fit, form and function
• Part of the VEMO range, a brand of the Germany-based Vemo/Vaico group that supplies quality aftermarket parts
• Each part is built for a specific application, so the exact pump is identified by its individual part number

Replacing a worn or failed auxiliary water pump helps restore proper coolant circulation and protects the engine and turbocharger from heat-related damage. It also helps keep cabin heating working as designed.
