Installing duel fan for radiator
I have had my C3 for 4 years and since I had my motor redone I have had a problem with the car running hot especially with the AC running and the temp is in the high 90s. I have installed an aluminum radiator. My mechanic has advised that we remove the stock fan and install a duel fan behind the radiator. I am looking for a duel fan and I am wondering which duel fan is the best to install.
Has anyone installed one and does anyone have experience on which duel fan to install.
Thanks
Joe

Are you sure its the fan? If you have a working mechanical fan that should be more than enough, seeing how they really pull a lot of air. Although they drain a **** ton of power. I'm just saying don't throw money at the problem. I just rebuilt my top end of my 355 and I replaced the pump with a high flow, put a aluminum rad in, and put a 16 puller fan onto it. While I can't say what the temp is running at since I'm going to be starting it today, I am hoping that its going to be completely fine with what I matched it too.

I put dual e-fans on my aluminum radiator (don't know brand of radiator), in heat above about 85* it gets too warm for me, here in Tx. it regularly gets above 100 so I had to put my damn flex fan back on

From what I've been reading there are a lot of cheap poor quality fans on the market that don't move much cfm.... I've read you need to move a minimum of 2700 cfm for a V8.

one of the reasons is that I installed a new parallel condenser for the AC and now that it is doing its job it gives off a lot of heat which is transmitted to the aluminum radiator. Plus the day the car got hot it was 102 degrees and I was running the AC on high. I would like to be able to run the AC no matter what the temp is. According to a few resources I checked with including the tecks at Custom auto air in Florida the next step would be the duel fan. On days that the temp is below 90 I don't have a problem.

That mechanical fan should be efficient for a typical sbc setup in a vette.
My factory mechanical fan cooled a lot better then the dual fan setup I went with. I first tried a single 16" spal and it would run about 225+ in 75 degree weather. Bought focus fans ($75) and installed, kept it around 215. Keep in mind my car would run 185/190 in 100deg weather w/mechanical fan. I checked to make sure all my radiator seals are in place and chin spoiler. Had new hoses to rule out collapsing on suction side of pump. I even put stock water pump back on in place of my hi flow and still nothing changed. I have 10.4:1 compression ratio and aluminum heads in my 383ci.
Installed dewitts aluminum radiator w/focus fans and left my 160 tstat in. It wouldn't hit 150deg in 85 deg weather. I installed a shaw 180tstat and it runs at 170 in 100 degree weather.
Good luck with finding your issue.

I have put in an aluminum radiator I spoke to DeWitt and they suggested the duel SPAL Fan set up. My mechanic has agreed. Again I think that once I installed the parallel condenser for the AC it is now doing its job sending heat to the radiator.
Hope that takes care of the problem.
Thanks
