It started a few weeks ago.My fan runs constantly(from when i first start the car till it turns off and now even afterward) and when i'm on the freeway if i'm in 4th gear and in a high rpm, my temp rises quick as hell and takes a while to cool down.I know the little bottom piece that bolts to the very front of the bodykit of the front bumper is hanging and i'm not sure if that's a major problem or not.And today when i got home, i turned the car off and the fan was still running.I just discoinnected the battery and went in the house not even wanting to mess with it seeing that i had just gotten off froma 12 hour shift.Can someone please give me some input on this problem if you know any?

Thanks,

Will

 

Yes the airdamn is very important to the cooling of our cars.The fans will and should run after you turn it off as the tmp. will rise when you cut the car off. due to no coolant flow.
Good luck,
Mike

 

But it seemed like it was on forever and it's never stayed on any other time since i've had(1&1/2 years).I'll see if it ever does turn off.I just don't want it to burnout before i buy another fan setup.Plus i didn't turn the car on for 12 hours today while i was at work.And when i connected the battery back,it came right on.

 

Ok, sorry, but this is really long. But hey, that's me, lol.

First, as stated, the airdam is very important. It directs air up to the radiator when the car is moving. Damaged or missing, the engine will heat up. So that's likely one problem, and it probably caused the other problem with the fan.

The fan(you said only one, right?) shouldn't keep running after the ignition is completely off. And if the key is out, then it's a good indicator that power is definitely off--unless the ignition is bad, maybe slightly sticking in the ACC position even when off, which I'd doubt.

So if the fan is running even after the ignition is off, then somewhere along the way of the wiring, a grounding out or short is occurring in a way to still let current pass directly from the battery.

There's a fusible link next to the battery that sends power directly to the fan relay, and the relay is connected to a fuse in the fuse box under the dash, from where the power is turned on and off with the ignition.

So working in reverse, if the fuse is blown or the fusible link has broken down, then there should be no power, and the fan wouldn't work at all. But that's not the case, as we know it's receiving power.

The fan switch operates by being grounded. So if that's melted-down or grounding itself somehow, it should run all the time--but only when power is on. If power is off, it still shouldn't run even if grounded. So that's apparently not the case either.

So that leaves the fan relay itself, which does receive a direct current. If the engine was running too hot all the time, due to a faulty airdam, then the fan would run all the time, which could eventually fry the relay in someway--usually to the point of not working at all, but possibly in a way so as to cause a ground or short inside it that's allowing power to pass directly to the fan.

So in summary, after all this deduction, lol, I'd guess that your fan relay is bad. And since everything else seems to be working, supplying power everywhere, it seems like it couldn't be anything else. Get a new one and see what happens. It's an easy place to start.

 

Hey thanks a bunch man.I'll do that and see what happens.IS it hard to swap out?Or is it right out in the open?

 

Not hard at all. Just unplug one and plug in the new one. They're inexpensive, too. Just be sure the ask for the one for your car, whatever it originally was set-up for.

On my Firebird, relays(two, it's a TPI car) are at the end of the radiator, passenger side, near the bottom. I think Camaro relays are in the same location. I'm not sure what your engine was originally, though.

You're running a 5-speed with a 350, which didn't come together, so I'll guess the 5-speed is original, and the 350 was swapped in. And if your car has only one fan(because you've only mentioned one), then I'd think your car might've originally been a 305 TBI or V6 car?

I think the fan relay for the V6 cars is on the firewall, driver's side. So the V8 TBI would either be there, too, or at the radiator like the TPI cars.

 

Oh man thanks a bunch.I'm gonna do this whenever i get time.I really appreciate your help.This forum is great for third genners.
