I picked up my fan for 10 bucks today

Got the 10ga wire and the 30 amp relay, gotta get the stuff for high so I can do this

Which wires are which coming out of the Taurus fan? Also, how would I go about setting this up to come on only when it reaches a certain temperature?

[DTrem08]

Also, what type of fuse should I use? Also, what exacltly does the relay do, and I'm a bit puzzled by how to wire it up. It's got 5 pins on it, thats about all I know...

[DTrem08]

Anyone?????

For a 30 amp relay, a 30 amp fuse would be beneficial, I presume.

Black is ground, and I want to say yellow tracer is the high side of the fan. Jump it straight to the battery to identify. It won't bite...too hard Just make sure you have a good hold of the shroud - fan will try to jump when you find the high side...sucker's fast

Ok....I got the 30 amp relay....5 pins on it, no clue how to hook it up. No instructions included. Looks like the one in the picture in the instructions....thats all thats holding me up now

What part number is on the relay? Gotta be a schematic online.

how do you want to activate the relay, a switch?

[DTrem08]

Yes, I have an on-off-on switch that I will be putting in the console area.

Also, anybody know about getting temperature sensors or something so it only runs when it has to?

I will get a picture of the relay up tomorow

you can add any temp sender you want to gound out the relay at the desired temp


you proably have a bosch spdt 85>86 30>87a,87

you'll want to sequence that temperature sensor with your T-stat opening temp. so that your stat will be open wide or close to it before the fan comes on, that way you will be utilizing all it's potential, but if you bring on the fan too early your stat will never open.

so how does the fan coming on too early regulate the temp of the engine itself when the tsat is closed and the water isn't moving? the fan cools the rad, not the engine.

as long as the fan comes on sometime before the t-stat opens you're ok.

You just explained that point perfectly. It doesn't.

sorry, i confused myself

if the fan comes on too early the tstat will never open? i'll have to disagree

[a70eliminator]

yea your thinking is ok, and I'll agree it won't make much differance other than your running that power eater for nothin, till that stat does open.
say your stat @180 begins to open, wide open @ 190 maxed out
You'll want the fan to come on somewhere in that same range.
It just makes more efficient use of the cooling system. IMHO.

So if I have the stock TStat in my zj, what temperature would I want the fan to come on at and how would I go about wiring it?
