Last weekend I went searching for parts for my Camaro. The only thing I found was a Hayden 16" electrical fan. Will that move enough air to keep my stock 305 cool? I've been wanting to upgrade to an electric fan on my car. Any help will be greatly appreciated. Thanks!

 

we would need the cfm of the fan, size doesnt matter if it doesnt move enough air. ive got a single 16" 2100 cfm fan that moves more than enough air.

 

Oh ok. I'll have to do some research on the fan. Now I have an idea of what to look for as far as cfm goes. Thanks for the help.

 

My 305 needs a lot of fan to keep cool in the summer.
You can always mount more than one fan.
Be use you have enough alternator to run them.

 

i dont see more than 1 16" fan fitting. unless you go with a smaller fan. which i had 2 14" 800cfm fans on there before going to the single 2100cfm 16" fan, and those barely fit.

 

If you keep an eye out you can find the stock dual electric fans for good prices.

 

From what I've seen online the 16" fan is around 1500cfm...I still need to see if I can find a part number on my fan because there is a hi flow 16" fan too. For now I'm going to try that and see how it does. Fortunately, the summers here are not that bad...didn't have much of one this year.

 

i should mention the 2 14" 800cfm fans were in there because i had a 388 cu in stroker motor. if 1600cfm will keep that cool, im sure 1500CFM would be fine for a 305 in a mild climate.

 

I did some comparing of the fan and how much of the radiator it will cover, and I don't think it will cover enough to really keep things cool. I would have to build a shroud for it to work well, and I don't have the time/money right now. I did find a mid 90's taurus fan in my shop (a while back a friend of mine bought two and said I could use one) and it looks like that will work better.

 

Guys have been putting those taurus fans in there full size chevy trucks and they cool them very well. Should do you good.

 

I am right now installing a Flex-a-lite dual electric cooling fan #480 in my Z28. The fan is located but not electrically hooked up yet. Now, the stock LG4 305 is long gone and a ZZ3 was dropped in a while back along with a Be-Cool aluminum radiator. The stock single electric cooling fan was never able to keep up with the heat generated from the new motor. The single fan did not cover enough of the rad to effectively cool things down as well as probably that it didn't pull enough cfm. Does your 305 need such drastic measures, probably not. But I remember once or twice the LG4 bubbling over into the overflow tank. I would opt for as much fan as I can afford. Get a dual fan if possible and one that covers as much as the rad as possible.

 

I have problems with my 85 T/A getting hot I put a larger radiator in it 160 deg. thermostat, and a 16" 1500cfm electric fan durring the summer I leave the fan on all the time when winter hits I hook the wire back to the sender so it gets above 160. although it still gets hot on nice days wok in progress. it drives me a bit crazy. 1700cfm not 1500

 

I agree with the dual fan idea next summer I am going to try that now that it is cold out the problem is reversed. I don't know if camero uses an air dam Pontiac does if yours is missing it will cause over heating as well.

 

I have dual 12 inch fans on my 87 tpi, Im not sure what the cfm is, but I know that when im sitting in traffic the temp goes to about 235, which i know is way to hot, but when I start driving it goes down to 190. I was thinking about removing the electric fans and putting a single 19 inch mechanical flex fan that mounts to the waterump pulley and install a fan guard/shroud. Are those types of fans better than electic fans?

 

I just put a flex a lite fan on my car for now because the relay/controller I bought isn't rated for the amp draw of the taurus fan I have and I can't afford it right now...have to get other parts for the car to get it going.

I've heard horror stories about the flex a lite fans coming apart, but the one I have is around 6 years old and it worked great on an old chevy truck I had.

 

The one im gegging will be new, autozones brand, Torqflo/19 in. dia. 6 blades , Im trying this because ive tried twice to put dual electric fans on but still cant seem to get the temp down while at idle. Im sure its either because of the flow or the cfm or something, but it's getting to pricey to keep experimenting with electrig fans, and its getting tiring always worring if its going to overheat. Im just going to bolt it on directly to the pulley with no clutch, I was told its about a 10 hp lose, nothing noticable for a 350 tpi. and the fan and shroud will cost me less than $70. I have a friend who has a mechanical fan on his truck and the air it pulled at idle made your hair fly up, when i have to conduct the "paper test" on the electric fans just to see if they are on. I think mechanical pulls way more air, alot less complicated, and cheaper.

 

the efficiency of the fan depends on more than just the size and cfm. if it has no shroud then it pulls in surrounding air instead of pulling air THROUGH the radiator.

alot of people have run the stock cooling set up on bigger motors with no issues. a properly functioning stock rad and fan will cool a stock-mild motor with ease. 235* actually isnt that much hotter than GM wanted these cars to run. the stock fan doesnt even come on until about 230*. if you want your fan to function its best, it needs some sort of a shroud.

 

yes it does have an air dam. the air dam is used to pull air at highway speeds and will cause overheating at those speeds if its missing. it really has no bearing on the cooling system on surface streets or at low speeds.

 

Yes I know all to well if I could go 50-60 mph everywhere I'd only have to worry about overheating for 2 months out of the year. It made abig difference running my fan when I want not off the sender. You can just unplug the wire from the sender , and tie wire it to groud. Then your fan will turn on when you start the car and stay on I think you can get a sender that starts the fan at a lower temp. the 160 degree thermostat helps alot.
