Are Thermo Fans Better Options Than Running Standa

[ylwgtr2]

oh and i made my own controller up that you can adjust the degree you want it to come on and the hysteresis....but now vdo have these....but they may need to be modified to see the correct Ohmage from your sender as they dont seem to go down as far as the nissan sender does(it piggy backs off your temp sender)very easy to fit

[psybic]

Have you got an electric water pump?

<{POST_SNAPBACK}>

Nope.

Pretty sure its doing no harm tho. Might even be some sort of convection current if water is hot in the block and cooler in the radiator?... maybe... i don't know these things...

All theory aside, the results are the main point and the results are awesome.

The reason I asked is that there is no point in running your fan after the engine has shut down because the coolant isn't circulating - unless you have an eleectric water pump that also runs after the engine is shut down.

[psybic]

Which is why I already answered by saying I didn't think it hurt. I knew what you were getting at. I think the main reason, is its easiest just to hook up straight to the battery.

Rev210,

Any pics of this 16" thermo sitting in the std shroud?

I assume you simply screwed or some how attached the thermo in the location of the normal clutch fan to the factory shroud?

Might have to do some measurements.

I've previously ran 2 x 12" davis fans, it was fine apart from sitting in traffic on a 30+ degree day with the a/c on. Temps would creep to the H.

Was the kit/controller that you piggy backed from the stock sensors able to interact with the thermoswitch?Was it a thermo kit specifically made to run a thermoswitch?

Sounds like the go.

Getting the fan to fit under the cover shouldnt be that hard.it would be hard though to make a new shroud cover.

How close are they meant to be mounted to the fins??

I dont understand why people dont use the factory shroud with a 16" fan set up on a thermostat so it turns off when on the highway. Wouldnt this make the most sense?

<{POST_SNAPBACK}>

Sounds logical to me. This is what I have.

Have had no dramas with it during Summer, and it is not possible to have any dramas unless, the fan cannot flow enough air or, the thermo plays up.

I am sure the flow is fine, and I trust the thermo as much as I trust any other thermo switch in my cooling system.

If it goes like you just described there wont be a problem.

No worries. I'm sure it doesn't hurt at all. I wonder what an electric water pump would cost and how hard it would be to install.

hey guys

i got a 16" thermo mounted in my R32 GTS-t within the shroud...i deceded to put one in after i fried my engine 2 years ago and the original fan was cracked so i went the thermo...i can't vouch for any power improvements as my car was alwasys changing and never dynoed it to find out but i can say they do a good job of keeping the car cool...i only really have to turn it on if i am stuck in traffic for more than 10 mins or slow speed driving on hot days (like 30 and above) most days i dont even need to turn it on..i have it wired to a manual switch near centre consol.

bit hard to take pics of it in shroud but here's two pics

i think people just need to remember standard car standard type temps but more power meens more heat so if your going to spend money on power ups {normaly $$$$} spend the extra {$} on temp control ie {oil coolers better radiator or fans etc

The controller i made mounts inside the cabin where the fuses/diagnositic connector is....it has two led's on it a red and a green ....so when the ign is turned on the unit powers up(red led)and when it switches the fan on the green led lights up.....it has an input wire(from the temp gauge....(i snaffled in to it from the plug in the dash cluster)a positive,an earth and the output wire(to fan relay)so no added senders/thermoswitchs needed)I also used the original fan relay....so if you looked at the car....it all looks original.....i used EF falcon fans....even they look original!

I too run a 16inch daves graig thurmo fan inside the shroud my setup differs only in that i run a haltec ecu which is set to turn on the thurmo when the thurmo stat opens and runs till 5 degrees after it closesso it uses the engine temp sensers to maintain temp controll and had no probs with over heating even in traffic and only slightly up when dyno tuning

Glad i read this i am going to do a conversion to thermo on my 32 soon. Thanks for all the info peoples.

[Bass Junky]

hmmmm

ylwgtr

It's not a similar electronic kit to the ones on Autospeed is it?

not sure pete....havent seen that one

[Sarumatix]

damn my stock fan ate the shroud so I think that option is out . EL falcon thermos are mentioned in another thread. I'm interested in some photos of these setup.

[J_R32]

how do you guys fit the thermo within the shroud?

I would like to hear more about this 'controller' you made....so basically it turns off / on when a certain resistance is reached at the temp guage???

[rev210]

16 inch fan within the shroud means a little bit of plastic cutting of the shroud. The radiator needs to come out to fit it correctly, it's very easy to do.
