Fan turns on after car is off.. normal?

[krott5333]

Often after turning my car off, a few minutes later the fan will turn on, then awhile later it turns off.

Is this normal?

[krott5333]

nevermind, i found it

[Luis 89LXi]

I put my axiliary fan last week, in hot days it start working itself.

just happens on the aux fan, I read in some post is normal, i don't worry about it

[Blue Impact]

It's pretty normal. No, I'll take that back. It's abnormal. :D When others remind you (about the fan) that your car is still on, tell them it's your turbo cooling down. At least that's what I do. :D

my fan doesn't kick in when car is off ?? is there something wrong ! it's carbed !

[shepherd79]

my fans don't kick in.

[A20A1]

I thought only LX-i's did that... I never new the carbed cars had it too.

[89accord_lxi_coupe]

my lxi does. if you look under the hood, there is a sticker on the frame above the radiator. it tells you that the fan will turn on automatically. they can stay on up to 15 minutes. if you haven't removed the stickers from under the hood, and there isn't one referring to the fan coming on, then it probably doesn't do it.

mine's the same way, and i still have the stickers too.

[CARBurn]

Nope, only Lxi's have that feature which is strange because when I had an 86 Civic Si hatchback the fan never came on after turning the car off, but it does for the Accord. Hondas do some strange things.

[Not like a rock]

My fan kicks in normally and keeps going after I turn the car off (goes 20-30 seconds and stops). This is in my 89 SE-i. I don't remember it hapening in the old 86 EX-i, and everyone gives me a funny look when the fan keeps going.

So, is it supposed to do this? Or can someone refer me to the thread that explains this? I also have the sticker.

[Gregs89AccordLxi]

Yea mine is a lx-i and does the same thing, mine sometimes last 10 - 15 minutes after the car is off, my dads 3g lx doesnt do that, when he turns off his car his fan kicks off.

[A20A1]

Maybe they added the extra cooling function just cause of the EFI's higher compression, higher hp, or the fact it was more of an up scale model of the Accord unlike the LX DX.

[krott5333]

basically the LXI is for tru ballas, and thats just another luxury feature

[89accord_lxi_coupe]

well hot diggity im a balla!!!! it's to cool off the engine and all. probably because of the FIs. it's doing what it is supposed to do, unless it goes longer than 15 min. then you might wanna get it checked.

[88' Accord Ltd]

The fans on my EX-i never come on after I turn the car off, and I know they both work! But then again I guess its no big deal..

[accordlxi2.0]

mine don't do it either unless i don't stay out there long enough.
cause one time it was bout 80 out and i went to open my hood expecting for a hot engine and it was luke warm. does'nt all of the 3g come with a fan timer.even carbed

[smufguy]

if u look on the hood fuse box, there is a relay and a fuse for the sub coolin fan. And all efi 3gs have a fan control unit under the passenger side seat (the black box near the shifter side) this module controls when the fan turns on and then turns off after the car is shut off. So yeah, its normal and carbs dont do it.

[accordlxi2.0]

do you have a wiring diagram for the efi cooling fan's?

[Justin86]

Yea it is only for the EFI.

[BITESIZE]

Thanks to those smart little japs.....they turn on when you're engines hot, even when your car is off.......Thanks little jap people.... :)

[accordlxi2.0]

but does anyone have a downloadable wiring diagram

[krott5333]

hahahaha little japs, hehehehe, theyre like little oompa loompas of the honda factory.

[Outlaw]

Does this really accomplish anything? (mine does it every time I turn the engine off, and it does it for the full 15 minutes every time) The way I see it, this only cools the coolant that is in the radiator. Since the engine is not running, the cooled coolant never actually gets pumped to the engine...

[accordlxi2.0]

but in the process the t-stat is open. So some of the cool coolant ends up going into the engine.

so i take it noone has a wiring diagram for this?????????????????????????????????????????????? ?????????????????????????????????????

[BITESIZE]

Usually I don't ask questions about why those (oompa loompas of the Honda factory do anything, mainly becuase they did things for a reason.

P.S. Why do you need a wiring diagram? Just curious.

[pip]

yeah they could care less about us carb guys " we got any EFI enignes? nah, just throw in this, we used this in our trucks in ww 2 against those damn yanks. hey whats about hp kazu? screw those cheap bastards they wanna buy baseline they can drive in the right lane"

Would a crappy scan of the circuit schematic help? :confused:

EFI Fan circuit schematic (http://members.nccw.net/heywood/Fan%20circuit%20(EFI).jpg)

[accordlxi2.0]

cool!!!!!!!!!!!!
thanx!!!!!!!!!!!!!!!!!!!

[UNIONSPARKY]

It is only for the EFI, If you look under the cover of the fuse box under the hood there is a fuse named fan timer circuit this turns the fan on when you shut the car of (if its hot enough) if you pull this fuse it will act just like it doesn't have this feature

[89accord_lxi_coupe]

somebody mentioned the box under the seat, that controled it right? the one that is closest to the shifter. well what is the one that is closest to the door. their was a thread about it somewhere, but i can't find it.
