Ford Contur Dual Radiator Fan?

This can be powered either by constant or ignition hot depending on whether or not you want the fans to shut down immediately when the ignition is turned off; mine is constant and the fans slowly turn off about 10-15 seconds after shutdown. If you open the switch (the yellow wire isn't seeing >6 volts) the controller will shut down.

Then run the 10 ga fan power to the battery with a fusible link (supplied in the kit).

I thought of doing that, but I'd like to have a warning lamp in place that'll come on when I have the fan killed.

Granted, if seeing a bigass red switch guard open isn't enough of an attention-getter, I need to have my eyes checked again...

Having just seen the DCC controller on the web site....how do you connect the fans...it looked to me that it just hase one connection point. DO you wire both fans to the same connection point on the DCC controller? I don't recall seeing any really good pictures or instructions on the web site about dual fans?

Yes, you wire both fans to the single output stud on the controller. It runs both at 0-100% based on radiator temp. You also need the filtered surge protector (1.5 KS on the accessories page).

I have a spal controller which as I understand will control two fans with the addition of another relay setup. It can vary the speed of one fan 1 and can turn fan 2 off and on, as I recall.

Rright now I'm running about 203F or so in town and about 210F on the hwy. Truck will cool down to around 200F at extended idle. Aftermarket 4 core raidiator and one 16 inch SPAL fan with a "custom" shroud. THe fan is offset to the drivers side of the radiator to clear the water pump. I've debated on trying to install a couple of "flapper valves" in the shroud to allow better air flow on the hwy but I don't know anyplace that sells them. I have the A/C condensor installed but have not finished the setup for the GM/ Toyota hybrid A/C yet.

Can someone post their temps.... with ambient weather in the 80's or hotter. Don't know where the temps are going when the A/C starts to work... I assume they will increase.

Don't know if I can get better cooling than the setup I have now? See attached pics.

Anybody have any info on "Flapper Valves"? I've been considering somthing similar.

I was never able to find anything on the web. I suspect that some of the hot-rod fabrication shops either make these things in house or know of a source. I never came across any good information. I've seen pictures, but so far I've not gotten beyond that. I think some of the OEM fan shrouds of various mfg have these things made into them.

Post a "flapper" pic if you can find one.

Thanks.

Is your filter connected to the ground and the output studs? That's how mine was secured to the controller when I got it.
