Any recommendations for or against an aftermarket electric fan? Anyone have success, failure? Do they work well or just so so?

I put dual 11 inch fans from SPAL on my 462, 244/258 hydr roller, ported 6x-4 headed engine.It´s a high po street car. Low 12´s on my G-tech, at the stoplight..The engine makes more heat than my RA4 400.I noticed that in coming at a stoplight after a long 3000 rpm highway cruise(165 degr), the temp goes up real quick and the fans switch on at 195 and off at 160. I really have to get used to them.I keep looking on my gauge,which goes up and down.Also when switching engine off, temp goes up to above 195 due to coolant not circulating, and when I switch on ignition you hear the fans turning on, so make sure you wire them through the ignition switch that when you start they are off.They will suck some amps. I had to upgrade my alternator. During cool weather it really cools great in traffic, on and off in 55 seconds!. The other day it was a little hotter and the fans were on much longer, but temp stayed at 190. I am not sure about a 100 degree weather traffic jam though, haven´t been in any ....yet. I got the fans because I´m getting a Procharger soon so I needed the space up front. It looks much better in my opinion. However I would not recommend them for a `normal` upgrade though.Too much of a hassle, hi amp alternator,wiring, switches, etc. The mechanical fan keeps your engine at a constant temp, you can forget about it basically. Also no performance increase was recorded on my G-tech. But every engine is different and this is just my experience. Hope this helps.

I used a fan off of a 87 fiero gt on my 71 firebird. I used the fan relay off a 88 firebird and ran it to a switch inside and a hypertech 160 switch to turn it on and off automatically like the other guy has. I also have a flow cooler water pump from summit and a griffin aluminum radiator it think its the 27.5x19 $189.95. I have had zero problems with overheating in the nasty humid hot air here its never gotten hotter then 180 in traffic and sitting in the lanes at the track it stays at 160. I run 7.60 at 90 in the eigth with 3.23 and unported d ports so its got decent power its cooling. I have had no alternater issues. I like it a lot better then the stock thermo fan it revs easier and runs smoother. I'm going to put one on my 91 truck next.

I installed a fan set up from a 98 corvette in my 72 firebird, dual fans my radiator is a 27x18. They work great and the parts can be purchased seperatly at the chevy dealer. I now have installed 2 sets of these and both work great.

Dutch,

Where did you get your thermal fan switch? Do you have a part number? I used a dual electric fan set up from a '95 Ford Windstar. Minor knotching around the pit cock, etc. fans work great. I have a 170° fan switch and would like to add the 195 and have the fans come on at different times. One fan will do most of the time, but adding the second when it hits 195° would be great.

Thanks,

Kevin
