2G Radiator Fans Wired Straight To Battery?

[AlmightySo]

My radiator fans never turn on and I always over heat. So I woke up yesterday and found some speaker wires an hooked the fan straight to the battery. Is this safe? What bad could happen? Or whats the right way I can set it up where I can switch the fans on & off manually.

It'll drain the battery, since i'm assuming they run even with the car off. You can always run a wire into the dash with a toggle switch on it. I'm sure there's a better way, but this is the "easiest" i can think of.

Assuming you have no AC, wire to that switch as On/Off

You could also figure out why the fans don't kick on and fix it correctly. Using a small gauge speaker wire for this is an awful idea. Very good way to start a fire.

Totally agree. Should just be a relay. I feel bad for not stating the exact same thing... What was I thinking?

I'm assuming this is some cheap, thin 16 gauge wire, and not something bigger like 12 gauge? Anyway, if the wire is too thin, it can short/burn up and cause a fire. Find the problem and fix it, or just use a toggle switch to turn it on/off. To me, though, it seems like it would be a pain to have to keep checking your coolant temps and switching the fan on and off.

I have it set where I connect the negative wire to the battery when im ready to go, then pop the hood and disconnect it when I turn the car off. I really would rather have it manuel because the guy I got the car from has some horrible wiring and the rad fan fuses might be blown. & thanks for telling me bout that fire thing.

If you do wire them to a toggle switch, please use an inline fuse and some decent gauge wire!

I completely ditched the OEM fan electrical system and wired an adjustable fan controller from Adv auto. I believe the brand is Imperial. It has an adjustable controller, relay, inline fuse, and thermoswitch that screws into the radiator. (works great on a 1g, don't know if you have a bunghole in your rad) There is also a version with a thermoswitch that you stick in the fins on the radiator, but I didn't like that idea.

I've had the same one for 6 years. I actually have 2 now since the relay isn't big enough for both the Spal fans I have, but I ran both stock fans with it for a while. It's around $70.

I dont know how to do any of that, could you possible give me a list of what I need and steps how to do this? Thank you!

It comes with pretty straight forward instructions and I think everything you need is included. A basic wiring ability and a few simple tools and connectors are needed.

The push in probe comes with the other part number 226204.

I think it was actually in stock at my local adv auto when I bought my second one.

If you do a toggle switch than you need a relay. There aren't very many switches that will handle the kind of amps that fan pulls. As i said earlier, fix the problem the right way. Guy a multimeter and go to work. It is very simple. IF you aren't willing to fix something as simple as this than i would sell the car, because it is going to end up blown up soon with the way you are taking care of it.
