The plan is to replace the old HP stealing mechanic water pump for a Manually Controlled Fan & Electric Water Pump. I did not buy this to save money, only for pure fuel economy. It is also part of my belt-less engine project.
Here is its caracteristics as it is ritten on the box :

Operating Temperature : -40°C to 130°C (-40°F to 266°F)
Pump Design : Clockwise Centrifugal
Motor Life : 6000 hrs at 80°C (176°F) and 12V DC
Pump Weight : 900 grams (2.0 Lbs)
Pump Material : Nylon 66%, 30% Glass Filled
Seal : Ceramic Face Seal
Burst Pressure : 350 kPa (50 Psi)
Fan Digital Controller Technical Specifications :
Input Voltage : 12V DC to 15V DC
Output Vge olta: 5V to 15V
Maximum Current : 12A
Operating Temperature : -20°C to 60°C (-5°F to 140°F)
Targeted (Set) Temperature : 75°, 80°, 85°, 90°, 95°C (167°, 176°, 185°, 194°, 203°F)
Controller Type : PCB with Micro Processor
Sensor Type : Thermister in Waterproof Housing
Fan Cut-In Temperature : 3°C (5.4°F) Above Set Temperature
Time Out : 2 Min. (Or Set : 5°C/23°F) After Ignition OFF
Indicator LEDs : Temperature, Power ON, Pump Mode, Test and Fan
Weight : 90 grams (3.2 oz.)
Dimensions (Metric) : 101 mm (L) x 95 mm (W) x 35mm (D)
Dimensions (Imperial) : 4" (L) x 3-3/4" (W) x 1-3/8" (D)

After maybe a week of DIY thinkering and working, the electric water pump is installed and ready to work. It as been a pain in the ass to install this thing. But it works well as far as we can see.
After reinstalling the serpentine belt on the crankshaft, Mechanical water pump (Now an Idler pulley) and the alternator, and after reinstalling the frontal belly pan, the car was ready to take the road.
Here is a step by step of what we have done to install the electric waper pump and EWP & Fan digital controller :
Step 1. Remove the serpentine belt from the crankshaft, mechanic water pump & alternator.
Step 2. Remove the engine coolant.
Step 3. Remove the Mechanic water pump, open it and remove the gasket.
Step 4. Remove the impeler
Step 5. Put a new gasket and close the mechanic water pump, reinstall it to its stock place.
Step 6. Remove the coolant pipe that goes from the mechanic water pump to the radiator, and install the electric water pump on it.
Step 7. Replace the OEM thermostat for the digital contoller sensor, put PTFE sealant tape around the threaded body of the sensor, fit the sensor assembly in the threaded nylon adaptor and thighten.
Step 8. Do the wiring from the electric water pump and the thermostat to the EWP & fan digital controler.
(Here is the EWP & Fan Controller setup, it is nailed downside of the radio emplacement.)
Step 9. Fill the engine coolant reservoir with engine coolant.
Step 10. Plug the EWP & fan digital controller to the 12V battery.
Step 11. Start the car, and run the electric water pump for maybe 5 mins.
So thats it, we have now an EWP! thats fantastic. A premiere in the history of ecomodding perhaps?
