Inched forward on my fan install.

Picked up these brackets & clips... With the clips on the bottom of the radiator support, the brackets support the fan assembly just above the bottom row of the core, perfect!

Cut off the brackets to fit the shroud, attached with some bolts, and bingo the bottom is secure.

 

Decided i like those brackets better than the ones i had made for the top, going to pickup a couple more today, along with a bunch of 1/8 vacuum hose to go over the edge of the shroud... Then i can move onto wiring. Going to order a couple 70 amp relays off amazon maybe i can get this thing moving again by next weekend.

70 AMP RELAYS?!!! What are you running for fans? Holy Smokes!!!  I would be surprised if each fan needed more than a 30 A relay.

 Its funny that you posted that... I've been doing more reading all day before I order stuff and now i'm not sure. There are a million posts on these windstar fans, and many have conflicting info and confusing info.

 

Apparently the windstar itself had a 75 amp relay, but it was feeding both of the fans... so if running separate relays, a 30a each would likely be fine... I'm just not real strong on this electrical stuff, so trying to make heads or tails of what i'm reading.

My fan kit came with 60 amp relays.

Ben...most electric fans are fine with 30 A relays. The big dual fans that pull like 6,800-6,900 CFM only draw like 36 amps, with a peak of like 48 amps. So 40 A relays would probably be totally fine for those Winstar fans! If you want to go with 60 amp relays I would think you would give you peace of mind!

Now the fans only draw max amp for a brief period to get started. After that they drop in current. You don't have to size your wiring for the peak amp rating as the amount of time that it draws that is not long enough to heat up the wire. If your relays are on the radiator support and your wiring to the fan is then fairly short, you can use 12 ga. wire.

The high amperage is necessary to handle the jigawatts of power!

I'm not smart enough to wire two fans separately so the one electric fan I have is wired to a toggle switch.

Personally I feel those fans draw too much amperage vs. what else is out there but I suppose that's besides the point. Every time you go from one means of energy to another, you lose something in the transfer-- mechanical to electrical in this case. Mileage and performance go down with that much draw on the alternator, especially if the coolant system isn't very efficient and the fan(s) kick on all the time.

 After all the reading I've been doing I think you are spot on here. I think I'm going to run dual 40amp relays/fuses and a 200on 185off switch and call it gravy.

I wound up ordering a pair of Spal 40amp relay harnesses from summit. Arrived last night- Nice heavy duty wiring & relays. I'll wire them both to the switch to kick them on at 195 and off at 175 degrees.

Ordered a repop top plate as well, but found out it still hits the top of the shroud, so I'm going to have to trim it a bunch, or trim the tabs i added to the bottom of the shroud to drop it down a little bit more (i think thats what i'm going to do.)

Getting closer!

Finished most of my wiring last night, still need to hook up the sensor/switch wires and the keyed power from the fusebox.
Can't decide if i want to include a manual switch or not to be able to kick them on if the sensor doesn't do it when i want.

The wife is heading out for a girls weekend, which means i get to play with my car as long as i can keep the kiddos distracted!

 

borat

Should be able to finish up the wiring this afternoon and test this thing out running down to the DQ cruise in tonight!

Well everything's hooked up and it works great... Kicks both on at 195, 3 mins and it kicks off at 175. Awesome! Wired in manual switch as well in case for some reason the sensor malfunctions...

Unfortunately... Gotta have one setback. Temp sender leaks like a sieve. Instructions said not to use Teflon as it interfears with the ground connection for the switch... I torqued the piss out of it while it was running, but it just kept leaking. Not sure what to do.

I used the liquid Teflon on mine, so far so good.
