I'm thinking of installing an electric fan in my '77. I live in the Valley (Rio Grande) where it can get pretty hot during the summer. I'm in the process of building a new engine to drop in, and I've had a couple people mention that an electric fan may be good to go with. I just purchased an 18" flex fan, and was planning on getting a high output waterpump along with using Redline's WetterWater which is supposed to drop water temp as much as 30 degrees. Kinda stuck on which way to go (since I haven't installed the flexfan yet, I can still return it to Summit). So, I guess what it boils down to (no pun intended), is either sticking with buying the high output water pump and keeping the flexfan or, going with an electric fan and having to get an electric water pump. If anyones installed an electric one in their C3, what's your opinion, and if so, do you have to remove the stock fan shroud? If that's the case, is there a particular set up you used, shroud-wise? Any help would sure be appreciated.
Thanks, Marc.

i was aat the track saturday and and talked with a owner of a 75 that installed an electric water pump and he said it dropped his water temp 30 degrees

Electric fan doesen't mean you half to use a ecectric water pump.
I just installed a Dewitts alumiun rad. ecectric fans and a Hi volume water pump on my 75. yes you no longer need the shroud without that and without the manual fan you have a lot more room for service. Between the fans and the amps on my stero,I did half to increase my stock alternator from 63amps. to 100amps. just to make shure I hade enought .. the thermostat for the fans screws into your intake manifold mine is 185* on 165* off, great set up, a bit bore money than the flex fan but running way cool .............

Clarence,
thanks alot for the info man. Could you tell me what brand/model (size) of fans (dual setup I assume) and high volume water pump you purchased and where at (Summit, etc.)?

The water pump is a stewart anderson cast iron from www.ecklers.com for $89.99 there was three to choose from cast iron being the cheapest.the Fans our from www.dewitts.com and spaul duel 11" sp460 for $358.95 the Raditor is dewitts alumiun $495 the fans come with costom mounting brackets that will mount to stock system and complete wirring harrness if your planning on a hot summer got to do the fans and water pump also put in a hi flow thermostat 180"

Read a caution in another post about getting the coolant temp TOO low as that can cause problems as well. Remember to find a happy medium.

One of the members of my club was having overheating problems. He is using a stock water pump, stock fan and he added an electric fan ( purchased from a local speed shop ). The fan came with mounting hardware.
The combination of electric fan, stock fan and stock water pump caused his overheating to go away, even sitting for extended periods in traffic.

I have a dual













































I have a dual electrisc fan set up in my 70 corvette made by Flex-o-lite. It is made to fit the Corvette radiator. I love it. Just twist a knob to adjust the temp. Clint
