Water Pumps

Put reliability at the heart of your engine's cooling system



Our Range
Water pumps are at the heart of the engine cooling system and a crucial component for all watercooled Internal combustion engines. Simply put, the circulation of coolant driven by the water pump allows the engine to operate at the optimum temperature, prevents overheating and potentially catastrophic engine failure.

Protecting engines in over 50 countries worldwide, Comline supplies a high-calibre range of over 400 water pumps catering for all popular European, Japanese & Korean applications.








Prototype Testing
The development of Comline water pumps begins with meticulous prototyping to ensure complete compatibility with the chosen vehicle requirements.

During this prototype phase the water pump is also subjected to a series of performance and endurance bench tests to optimise pump motor operation, heating & cooling operations, pressure control valve operation and set vacuum controls for the correct internal suction pressure.

This exhaustive endurance testing spans a six-week period and validates the design and quality of the water pump before it enters production.








Recipe for Success
During the production process our water pumps undergo a 100% leak test to guarantee a water-tight seal and the consistent, reliable performance demanding by Comline.

This test runs to a defined protocol that also allows Comline to measure and analyse pressure vs flow at various RPM ranges and collect coolant delivery measurements based on suction head control.








Cavitation Detection
A fatal flaw that can severly compromise the performance of any water pump is cavitation - essentially the formation of bubbles or cavities which typically form around the water pump impeller.

Each and every water pump rolling off the production line is put through a cavitation detection test to ensure only world-class water pumps carry the Comline name.








Warranty & Traceability
Underlining our product confidence, Comline aftermarket water pumps are supplied with three-year, 36,000 miles (60,000 km) warranty.

Wrapped in our distinctive blue and yellow box livery, all Comline water pumps are also brand and batch code stamped for complete traceability.
