Hey guys

So ive been thinking of doing an electric fan conversion on my truck. What i was thinking of doing is wiring it to a switch on the dash to turn it on and off with the ignition in the run position. That way i wouldnt have to mess with the temp sensor and other stuff. Short and simple.

First question, I replaced my voltage regulator last month with an oem replacment, will that be good enough for the fan?

Two, i havent gotten a fan yet, but would i have to get a new battery to supply the amps?

three, Has anyone put an electric fan or electric fan and waterpump on there slant?
if so where did you get your electric water pump?

Im just looking to free a few ponies really. Thats it, nothin fancy.

Thanks for the input,
Cody

Has nothing to do with a fan Again, has nothing to do with the fan. I run an electric fan and water pump on my race cars, as do many others. As far as I know there is no good electric water pump for a slant six street car. The kind I have is like a heater blower motor, with a cog belt to drive the stock water pump. These motors are not designed, for the side loading the belt puts on the bearing, or the extra "load" on the motor. The motors overheat and burn up if they run too long. Also the front motor bearing will wear out fairly quickly. There are inline electric water pumps, but these also have problems on a street car.
You can run an electric fan with good results, but you might need to upgrade your alternator, to one with a higher output, depending on what is on the car, now. Easiest way, if you don't have one, and there is room, is a thermal clutch fan.

Thanks for the input,

See the FAQ in the electrical section, and also make a search, there are lots of posts about el. fans.

Ross,

My electric fan set up is really simple and documented in the Engine FAQ. Been running it for over 7 years now with no trouble using a stock alternator.
All the parts were well below $100 with a super simple schematic that is posted. I have two switches inside, one to arm the system and the other to manually turn it on if I want to over ride the temp sensor. No more heat soak and hot restarts are instant. More power and better mileage are both realized.

It's actually in the Electrical FAQs and not the Engine FAQs, isn't it?
