The Davies Craig EWP 150 Electric Water Pump is a high-performance, remote-mounted 12V electric water pump designed to improve engine cooling and free up power. It suits a wide range of vehicles, but it really shines in high-output setups like V8s, large six-cylinder engines, 4WDs, and builds pushing over 400 HP.
Instead of relying on engine speed like a mechanical pump, this unit delivers consistent coolant flow whenever it’s needed. As a result, your engine maintains better temperature control—whether you’re idling in traffic, towing, or pushing hard under load.
Beyond cooling, the EWP®150 also helps unlock performance. By removing the drag of a belt-driven pump, it reduces parasitic loss and sends more power to the wheels. At the same time, it can improve fuel efficiency and extend engine life by keeping temperatures stable.
To get the most out of the system, you can pair it with the optional digital controller. This upgrade transforms the pump into a fully automated cooling system. The controller adjusts pump speed based on coolant temperature, activates radiator fans when needed, and continues cooling after shutdown to eliminate heat soak. This is especially valuable for turbocharged or heavily modified engines.
When it comes to installation, you’ve got several options depending on your goals. The simplest approach is to run the EWP®150 as an auxiliary pump alongside the factory unit. If you want better performance, you can disable or modify the mechanical pump while keeping the housing in place. For the best results, remove the mechanical pump entirely and let the electric unit handle all coolant flow. While this requires more effort, it delivers maximum efficiency and control.
No matter which setup you choose, proper installation matters. Mount the pump low in the system, use soft mounting to reduce vibration, and plan for possible hose modifications in more advanced builds.
Overall, the Davies Craig EWP 150 Electric Water Pump isn’t just a replacement part—it’s a complete upgrade to your cooling system. If you’re running a modified engine or need more reliable temperature control, it’s a strong, proven solution.
