Has anyone installed the dual v8 fans on their v6?? If so, how hard, etc.

This one is usally drove in a congested town, and heats up quite a bit while sitting in traffic. This winter I noticed the fan dont spin as fast as I thought it would, or like.

 

I think the extra fan might draw too much from the battery. Check and see if the V8 models require a higher amp batt. Has your temp been out of whack now that the air is warmer? Maybe a ittle watter wetter could helpout. may or mmay not be cheaper than a new fan motor.

 

I'm actually doing this next. I'm going to mimic the setup I have installed in my truck (BeCool radiator w/ dual 14" Hayden fans)
Only with 12" dual Haydens. Battery draw is insignifficant- there won't be a problem.

 

The easiest thing to do is just put in the Hyper tech fan switch so that it can ground the fan relay. There is an extra hole next to the temp senosr, just take out the pipe plug using a piece of 5/16 square stock and put in the hyper tech switch. Wire it up using the wiring diragram in your manual and you'll have nice 195 F degree turn on temp in traffic and it won't go off till it sees 190 F.

 

If I were going swap the single fan for duel fans, I would get the aftermarket Flex-o-lite or Be Cool duel fans that are much slimmer and lighter and would probably take the same amount of jucie as the heavier single one.

 

I don't have the kinda money to buy a brand new fan system. I can get oem (salvage yard) parts cheap so thats why I am wanting the v8 system. Will it bolt directly up?? or are radiators totally different so that it wont??

 

Oh ok, I see now. I know the V6 radiators are different than the V8 ones, especially with the hose locations. I am sure with a little modification, you can get a V8 fan to fit. I don't think it will be a direct bolt in.

 

What are you going to use to turn on the other fan? If your just hooking both to the same computer controled relay you have gained nothing because of GM's high turn on temp. A $45 dollar fan swith (I had mine made from a engine controls catolog for $25) and a $1 piece of wire is the quickest and easiest setup. ON a v8 one sensor is in the passanager side head and the other in the drivers side. The use the hyptec fan switch IN place of the factory fan switch to control the pimary fan on v8's. All you have to do is wire it up to the relay, like i said above.

 

I do have a hyper tech switch that I bought a while back. It didn't work like I thought it would, so I took it back out.

So I could prob. adapt the dual v8 fans (with some slight fab work), have one controled buy stock wiring, then fab up the other fan to a relay system to come on buy the hypertech system.


So one comes on at say 185-195 or so, then the other kick in for "backup" at whatever the ecm says (220 isn't it)????

 

Well the ECM controls the fan on a v6 so when it sees 220 it grounds the relay OR if it sees A/C usage it grounds the relay.

All you have to do is hook up the hypertech switch to ALSO ground that same relay and leave everything else there, just splice it in.

As for a two fan set up, you will need the top piece that holds the radiator in and all of the other mounting hardware for the fans.

Yes if you connect up to the power distrobution block on the passanger side of the radiator and use a relay and a hypertech switch that could control one fan and the computer could control the other. It's a lot of extra work when all you need is a lower fan turn on temp.

Also remember that the 305 v8 Camaros used the same fan as our v6 models so the fan is MORE then enough when used with the right turn on temp.

 

How fast do these fans turn?? I know I can almost follow a blade while this thing is spinning. VERY slow, and I feel little to no air movement.

I was thinking this motor is about had, and when I replace parts, I like to get the "heavy duty" one .

For my budget vs my desires I felt the oem dual v8 would be my solution if it can physically mount up.

So I take it nobody has done this? Is their a reason why?? I don't want to have to buy a system, then find out it wont work for bla bla reason. Thats why I'm here asking first!!!

 

Yeah if you don't have a voltage problem at idle then I would say you have a fan motor thats had it.

I think your going for the cool factor on dual fans! rather then the cheap solution.

 

Yea cool, Keep that damn engine bay cool!!!

Who would see it?? And if they did, would they notice a difference??

The alternator is brand spanking new, so I doubt I have a voltage problem. No major stereo system.

 

Check with a meter at the fan and at the relay to rule out a bad relay also. Sounds like your sold on a dual fan setup so good luck on your project.

 

Let us know how the dual fan works! I've always wanted to upgrade to that, but haven't found one in a junkyard yet

 

I don't think adapting it would be too difficult, but I'm really surprised to hear that a V6 is running hot enough to need it. Between a fan switch and 160 thermostat, Shannon's runs way cooler than most, almost too cool.

 

I want to do the duel fan idea, but I want a new one. I have a strick new parts only policy for my car. I want my car to be like new when I finish building it.


My car could certanately use those fans on hot summer days ideling. Last Saterday, my temp rose to 220 sitting in the sun. That is hotter than I want it to be, so I want it to remain cooler while ideling in the hot sun and while using my AC.

 

LT1, thanks for thoughts on adapting.

As for cooling it off, it has a 195 in it so that the mrs could have heat during winter. She didn't care much for the 185 I had in it, let alone a 160 that I debated on. No manual kick fan on switch either.

I am wanting a system that I don't have to wonder if she notices it running hot, and has to manually kick fan on.

I would also prefure that I don't have to swap t-stats every season either.

I figured the dual v8 setup would be best for my buck, easiest, clean looking setup I could do.

Sure, buy a new fan motor, wire in switch, change t-stat every season. I prefure not to try all that. Buy then, im at 75 bux. I can get dual setup for 110-130.

Plus I can be a first (so I think) and I can add a mod to my list

 

Makes sense, just another way to go about the same thing. Guess not everyone has a girlfriend or wife that ports her own heads and does shift kits in the living room!

160 effectively kills your heater, at least for the first 20 miles or so of driving!

 

Dude, I wish my woman showed any kind of interest in cars, let alone ported heads and did shift kits. If she could do that, with all the spare time she has she could swap in a 3.4, port and polish my intake, heads, and even learn to freakin' weld. But alas, no interest in it what so ever. guess it all has to wait until I get off my lazy bum, huh?

 

She loves cars, shes the one who literly pulled my old engine outta my truck (all 85 lbs of her). She also installed the flywheel, motormounts, etc.

She doesnt mind going to parts store, or checking her oil, changing a flat when needed. And she DOES NOT ignore the little "service engine soon" light.

Shes also one who informed me of it running warm. But I still rather her not have to look at the temp guage every 5 min, to know if she needs to flip this switch or not. And have to both me every time the weather changes to put in a new t-stat.

I rather her eyes be on the road, not the guages!!!

LT1, you did find a rare one, I will tell ya that!!!!! Little rarer then mine.

 

The thing is, it does double the number of project cars...so time is always an issue! We have three full rebuilds going on, plus my "needs everything" 87 TA, RAIF, and her 454 dually, which has been getting more than its share of attention lately! Its great though, being able to spend "quality time " at the junkyard, drag strip, car show, club meeting, etc, rather than at some &%*( mall !

 

Amen :hail:

 

I never post anymore but for g0d sakes make sure you stay in proper running temps.

Why or why I ever listened to anyone.

after removing my AC radiator, putting on a home made air dam and with my adjustable temp fan control switch. I have been running at about 150f all the time, with no fan running.
[ the colder weather and my ram air do have some effect on it.]

It has now been more of a chore getting heat back into the engine. first thing to go was the air dam. You get 3 times the engines wear at lower than proper running temps.

Just some will make you believe heat is your enemy, when really its your friend and alley. I was killing my friend and killing my engine when I should of left well enough alone.

FYI, for the years 90-92 v6's and all v8's used the same radiator (look up the part # if you want proof) so thats one less challenge for dale

 

Everybody knows that, it's the mounting hard ware for the fans thats hard to find along with the different plastic part across the top for upper fan mountings.

 

Well Gumby to little heat is a bad thing and to much heat is a bad thing. The best temp for perfect combustion is 220 which GM likes to keep for emissions reasons. 150 degreess is way to low, you carbon up! 220 to me is TO much, electronics fail like crazy and conventional oil begins to break down. 200 is a nice temp. OR if you want to get tech. 205 outlet and 160 return is a perfect setup for HP.

 

Oviously not, if we have people giving out false information, like the member i just corrected

 

I agree with Ryan_Alswede. Obviously the v6 fan has a problem (motor, clutch). Fix/replace the fan. Then I would recommend getting a lower temp fan switch (again), and a 180* thermostat.

You shouldn't have a problem is cold weather cause Import cars use lower fan/thermostat ratings compared to factory 3rd gens.

Find out what the problem is with your current fan. Because this will save you the hassle of wiring the v8 fan...to find out later that it doesn't work the way to want it to.

Or you could get one of those single elec. fans, they're not too expensive, you'll gain some power , and they come w/ a variable fan switch.

The oem fan has completely quit working. Relay kicks over, have power going to where it should. Fan motor burnt up. My Dual fans should be here tommorow. Wiring will not be an issue. It will be cake walk after my engine swap I just finished.

My problem will be getting that GD 5/16 plug outta the engine

 

well if you don't have KED85 luck you can get a piece of 5/16 square stock at your hardware store and put a wrench and cheater bar on it and crank on it. Otherwise you have to heat it up like he did.
