anyone do E-fans on a obs??

Well make sure all your wiring is first before you start deciding what fuse to put in it. How many amp is the fan? post up pics of the wiring you have.

It's not wired up yet. I was goin to run 2 40A relays, and try and do what onebadsuv did.

Where is the temp switch wired to?

What is the temp switch wired to? Where?

The Ford efan is wired in where the "FAN MOTOR" is shown in the diagram - You need two bosch relays to split the load and a temp probe thermister to activate/deactivate the fan (where it says TEMP SWITCH) which is mounted to the radiator core . You can control the amount of run time the fan is "ON" by simply varying the placement of the probe ... if You put it next to the radiator inlet , the fan will kick in and run alot . If You mount the probe near the outlet like I did , you let the radiator do most of the cooling and the fan only comes on if there is no air moving through the radiator , like at a traffic light or sitting idle . Turning on the A/C will automatically power on the fan using the supplied wiring diagram plus manual override switch . I don't take the credit for this sweet wiring setup - I found it on the 'net posted by some kind soul
Best one I've found to date , and there are many floating around .

thats the pic of the wiring diagram again

I got the diagram except the temp switch. Does it only have a ground? (Looks as such) Where can I get one?

Can I use this as my temperature switch?

any temp probe should work. this is just telling when the fan to turn on and off

i would assume so but i'm not 100% sure.

Can I tap into the coolant sensor near the thermostat?

E-fans for OBS

Hi guys ,

Clearly I under-estimated the group interest in getting rid of our (OBS) inefficient and noisy OEM belt-driven clutch fan cooling ... rather than hijack Clean95's thread I will post an easy to follow "how to" along with pictures if members with questions need some help - PM or request here and I'll put it together provided there is interest

Absolutely! Can i put a request in for pictures specifically on the wiring portion of the install??

 

[AtomicHoe094]

i made a howto in the tech section for the flexalite fans..

 

[blizz]

onebad....yes please. that would be cool.

ya i'd be interested in a how-to as i want to do this mod this summer.
pics of how its mounted specifically would be nice

 

[sokr915]

yes please, i just picked up lt1 fans and need to install them

 

[Rudder]

I would definately be interested in a detailed write-up for an efan install on OBS.

 

[cmobile]

New to the site, this place is awesome!!

Thanks for the great ideas. I am so doing this mod.
Did this "how-to" ever get posted anywhere? A quick search proved fruitless for me.

Would like to see more mounting details from Onebadsuv.
