Electric coolant water pump
Introduction
Auto manufacturers are moving towards electric pumps for steering and cooling.
Aftermarket retrofits are available for some engines, though the gains are likely to be had only where they are computer controlled so power use is continually optimized based on engine temperature.

Instructions for mod
Hope there is a aftermarket electric replacement for your application.
Then once you decide how to install the water pump you have to figure out what you are going to do with the belt that was driving the pump. Some after market electric water pump kits have an idler on the electric pump. Most of the time you just have to get creative.
Then you have to find a way to wire it up. A key on power supply is best that way you cant forget to turn the pump on or accidently turn it off while driving. It is highly recommended that you use the "key on" power supply to work a relay and have the relay actually power the pump.
