Electric fan questions
« on: May 16, 2010, 08:45:27 pm »
I put in a aluminum radiator today, sweet.  ;D It was almost an inch shorter than the stock one, no big deal, got it to work. This is where I got it, it was a little cheaper when I bought it. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=120479345979&viewitem=



The whole setup came with two electric fans, which I haven't put them on yet. I was looking at the fan connectors, and it didn't come with the female ends. Does anyone know of a site that might have something that works? Local parts stores were no help, and I emailed the seller and he said they don't come with them. I would rather find matching connectors instead of buying a complete set and rewiring them.


Lastly, I want to wire them up, obviously, to a thermostat switch. Can I put the thermostat where the yellow arrow is? Any suggestions on a kit? What temperature settings should I be looking for, as in when it comes on, when it shuts off? With the old radiator, I ran the flex fan without a shroud, and as you can see in a earlier pic, it is far from the radiator. Ive never had any cooling problems with it being so far away. Would this kit be good? On 200, off 185 http://www.summitracing.com/parts/SUM-890016/?rtype=10

I put some female crimp connectors on the spades on mine. I think where either of your arrows will be fine.

I can't see your pics but is this the pigtail you are looking for?

Just get an adjustable thermostatic relay control. You can set the temp at which you want the fan to come on.

That plug is close. The fan wiring has the male ends, and the two ends are not separated by the plastic divider, as in the picture. Basically, I need the other end. I guess it wouldnt matter if the female end has a divider between the two terminals. Ill browse that site and see if I can find it.

If I were to get the adjustable thermostat, what would be the recommend settings?

Thats weird I wired up an electric fan a few months ago my fan came with all connections I ordered it from summit. I havent fired it up yet so I couldnt recommend temp settings. But I would think I would want mine to kick on a bit after 200 and off at 195 or so. You can probably never get it below 195 once she is warm.

I believe Radio Shack (or "The Shack") has what you are looking for.

My temp sensor for the fan relay is 3/8" npt but the hole in the intake is larger. I wanted to know where to get an adapter, but I found one at the hardware store.

if you still haven't found your connector i would take the fan up to radio shack and tell them you need the other end they should be able to get that style molex connector

Or, if you can't find the other side of that particular connector, just cut it off and attach a whole new molex connector. Just a thought, vs going crazy trying to find half of a particular part.
There are two tools needed, duct tape and WD40. If it moves and shouldn't, use the duct tape. If it doesn't move and should, use the WD 40.

Thats what Im going to do. I saw some GM alternator wire extensions which are pretty thick. Going to cut them up and wire them in and then loom it all. I just installed my thermostat relay kit the other day. Im waiting for a electric fan bracket kit to arrive and we'll see if that works.

Just get an adjustable thermostatic relay control. You can set the temp at which you want the fan to come on.

This is the female end of the plug, if you read the description. I believe it has the same terminals as our headlight plugs.

I already have the other wires. Even though the description says female, the pic shows male terminals. No biggie...
