EWP & CONTROLLER INSTALLATION DEMONSTRATION
Combined with an LCD EWP®/Fan Digital Controller (Sold separately Part #8002 or EWP® Combo Pack) will manage both the EWP® and Thermatic® fan operation. The Digital Controller will vary the speed of the EWP® in response to the engine’s coolant temperature. Multiple temperature settings are provided on the Controller for either maximum power or fuel efficiency. The Thermatic® Fan/s will be activated automatically once the engine coolant rises 3°C (5.4°F) above the targeted (set) temperature. The Digital Controller will automatically run on for three minutes (or to 10°C / 14°F below the set temperature) after engine shut down, eliminating ‘heat soak’ and extending engine life. The EWP® Controller Combo Pack is supplied in a do-it-yourself kit with everything you need for fitment to your vehicle’s engine, including an easy-to-follow DIY instruction booklet.

EWP® INSTALLATION OPTIONS
Installing an EWP® as an AUXILIARY PUMP
EWP® INSTALLATION – disabling Mechanical water pump
In both these cases, the EWP® will pump past the impeller of the mechanical water pump.
Disengaged mechanical water pump (recommended)
Removed mechanical water pump (Ideal)
In most cases EWP® will be adequately supported by the radiator hose. Where mounting is required, the EWP® must be soft mounted to protect against vibration. For the EWP®115, EWP®140 and EWP®150 Part #8700 or #8710 Mounting bracket is recommended.

My MGB is still 1800cc, but I was wearing a Fast Road Cam and HS6 carburetor, so I was struggling with overheating in summer when I was riding in the town. One year ago, I was told in a club magazine that I could do a cool run with EWP installed, so I searched Ebay and purchased EWP115KIT. Since the diameter of the cooling hose is φ30mm, it took a little time to connect it. Also, I purchased a rubber mount kit for installation, but because it does not fit in the engine room, I made my own mounting jig and installed it. When you actually start running, you can now cool run at low speed and high speed, and enjoy it without any problems.However, recently, when running in winter, the heater does not work so much, I have currently ordered WBP. I'm going to install it soon and hope to enjoy the drive with the heater working. I'm really happy with the EWP because I can monitor the engine temperature and power generation voltage accurately without worrying about engine blow due to overheating.
