Electric Water Pump
So, I am trying to find new ways to increase mpg. I just bought an electric fan and it will be coming Tuesday. I found this onlie and wondered what you all thought of it:

It looks like it just bolts up to your current water pump and rotates the pulley. It comes with a switch but i was thinking i could just wire it up to a switched source in the fuse box.
What do you all think?
EDIT: just realised the motor would burn up if the thermostat was closed. I read the directions it said you should remove the thermostat. Wouldn't that hurt your engine to run that cool?
Sounds like a lot of variables and trouble, might not be worth it.

RE: Electric Water Pump
Hmm... I dont think you would need to take out the stat... here is a little reading for ya.

the temp of the coolant is what makes it open and close, nothing to do with the water pump its self.
You would gain some MPG's adn HP from switching out to an electric unit, BUT and electric fan pulls a lot of juice, and so will that pump... not to mention the rest of the truck. Make sure the alt can handle the load you are about to throw at it.

RE: Electric Water Pump
so while it may be slightly more efficient, but it will accelerate wear on the engine and isn't as reliable.
The only way i see around it would be to wire the motor so it would kick on after the thermostat opens. Too much work and room for error.

RE: Electric Water Pump
One thing us drag racers have learned is electric water pumps are not for street use. they go one speed and if in traffic it might over heat or have other problems. Great for freeing HP at the track though

RE: Electric Water Pump
i see. I out in the electric fan from flex-a-lite and got it going good, but i had a question. I put the probe into the radiator fins, but i full like it might fall off during use from vibration or whatever, how did some of you who got that put it in so it wont? can you glue it on or something? i just want a little assurance so my fan kicks on. I could only get it in there a little bit and i am afarid of damaging stuff if i push it in too far.
