Yesterday my first time experiencing such a problem. It happen to my wife newly bough Proton PE. I was about to close my house door and i heard the radiator fan suddendly comes on. The car key already plug out and the door have been shut and alarms activate.

it is normal..

sometimes the fan is auto run, whenever the heat detected is high the fan automatically run, usually happen to me when turn off engine the fan will run quite some time before stopping^^

Oh, it's normal? Cause it never happen on my Honda City...

my 308 VTi does this once a while. I heard that 308 Turbo does this quite often, especially if you drive it hard before stopping it.

it's normal for update proton car, the fan will running a while to cool your engine to safest temp.
don't worry it will shut-down back it-self after that.

i wish to do that to my old proton as well.. last time i googled, they connect a relay to the fusebox... but not sure which one to which one... >.<

a timer relay

YA, THIS IA original PROTON Suck design .
i met this problem . timer jammed out and fan keep on spinning
the next day , Battery fully KONG

now this ia PROTON

if this system good , why Toyota , Nissan , Honda , perodua dun have such design ..?

maybe lotus car got ..

why only happens on u? so sad,

if like that, change the timer, they install with timer for safety reason, they don't simply install it for nothing

u know??..

This means that your car's fan and its electric thermostatic switch
is connected directly to your battery, rather than IGN (ignition)
or ACC (accessories), nothing to worry about.

This is in fact better as it cools down your coolant/engine/radiator,
rather than letting too much residual heat in the system and shortening
the lifespan of your radiator, hoses, seals, gaskets, head, wiring, etc.

Unless, of course, you have a very weak battery, or one that is
about to die off on you.


The thermostat (or they call it "sensor") is just a simple bimetallic strip,
same as what you find in your household electric kettle.

On shutting down your engine after a long drive, your thermostat
detects that it is still hot and switches on the fan. If your fan/thermostat
is connected direct to your battery, obviously the fan will run even
after you have taken out your keys.

On engines where it is connected to the IGN circuit, the fan motor will
only run as long as your engine is running, or your keys are in the IGN
position.

On the Iswara's engine, it is connected to ACC, so it runs if the key
is in that position. This is what I do in fact, if the fan happens to kick
in just as I switch off the engine, I will leave it at ACC to allow it to
cool down the system as much as possible before I go off.

Or, if it happens to come on just before I am about to switch off the
engine, I will let it run in IGN and then shut down right after the fan
goes off.

lol. no need to blame lar like this, everyone know proton quality, if u had problem send to nearest SC let them brain-wash u, no need to shout and complaint to much la.

talking about toyo and honda, their use different technology, and for sure their more advance than current proton.

No man, I know pinats about wiring. If you want you contact this sifuu wireman 019-2369963 and he'll gladly do it for you. Speaks chinese only. Wires for life, wires are his life

PROTON Did install a FEW Parts For nothing
want example ?

haha... nah, no point paying someone to do... dont feel the satisfaction of diy...

ok give some...

pls dont make this thread more funnier lar..
europe car already had. why such a hassle?
even my dad's 90' pugeot 405 gtx got this feature.

and actually proton are getting improve in their technology, the only problem with protons is the wear n tear parts lifetime. other consider ok.

tap the rad fan relay to the rear brake light fuis
since our saga rad fan is control by a switch at the bottom of the rad

The Fiat 131's fan was also wired direct to the battery.

If you are concerned, just ask your wireman to rewire
the fan's positive wire to ACC or IGN.

I don't think there is any timer. It's just your thermostat
triggering it off.

saga years 91 fan is factory tap at acc
iswara i dunno

Proton Gen2 , there's a round thing install on right side of steering , stick on dashboard . press it , would pop out . notice ?
any idea what is it used for ?

persona maybe also got .

brake light switch??..

Happen to me everytime I push my car engine really hard just before turning off the egnibe. The fan will keep spinning for about 10 min before auto turn off.

Same with me...

lampu berhenti nia

if we modify for this, does it will harm to the battery?
im interested too

yupe... i saw my friend gen2 doing this, means his radiator fan will run for few minutes after turn off engine, but not sure how to do that..

it's totally normal..same thing happens to my savvy when i turn off the car. esp when the engine is hot. the fan'll stop running when the engine temp is lower

i think only happen to newer car right ? old car not that "smart' lolx

how if old car wanna do the same thing ?

pls remember that savvy is using renault engine, as i posted b4, even oldies europe car already have this
its normal when its came from factory setting but unsure how to diy it.

Nothing very "smart" about this.

Like I said, it's just your thermostat triggering it off.

The mechanical thermostat is just a simple bimetallic strip. Heat
makesit bend one way (like your ..... ) and touches the positive
supply for your fan. Your battery, ACC or IGN is connected
to the other end, so it completes the circuit, and your fan runs !

http://www.ehow.com/how_5346168_make-therm...llic-strip.html


Same thing inside your electric kettle. When your water is
boiling, the bimetallic strip bends, disconnecting the power
supply for the heating element.

Same device too for your old electric iron, toaster.

Older temperature controls in car and room airconditioners
also use them. The current generation, like your Iswara
and Panasonic room aircons, are electronic, using thermistors.

Electric fans for FWD engines (and some RWDs) have been
around for decades. Where there's an electric fan, there's
a thermostat.

The newer radiator fan thermostat switches are electronic
and thermistor (temperator sensitive resistor) as in the
new car aircons.


You can do without the themostat if you wish. Just wire the
positive contact of the motor direct to ACC or IGN,
bypassing the thermostat. The fan will then run continuously
as long as your engine is running or the key is at ACC.

This was how I wired the aircon fan for additional engine cooling
last year in my old Toyota KE70. The condenser was in front
of the radiator, with the motor in beween. It was normally
switched on by the compressor's magnetic clutch, but I jumped
that and connected the positive supply direct to my ignition
coil's positive contact.


Otherwise, you can also wire it to a toggle switch on your
dashboard, so you can decide when you want to switch it on.

" ..... aftermarket ones are sometimes simply hooked up to
a toggle switch in the passenger compartment so that the
driver can decide when the fan comes on and when it turns off. "

Suspected that

other wire triggering the fan on ...and takes sometime to wait it stop

Kindly check ur engine wiring system properly .....

It might cause danger ..... ( wiring short cause burning )

my 2cents

get a turbo timer la
set 20min
then remove ur thermostate
add a aftermarket rad fan
comfirm ur engine temp should be damm cool when it shut down

clever la u... idle 20mins with engine running can cool down ur car one... u drive prius or insight mia kaa??...

as a matter of fact, many people install turbo timer on their NA cars. Really good business for car acc. shop huh.

what ???
a solution ma
even better u tap the rad fan to direct current and bypass the fan switch

same as perodua also..

usually happens after long drives or rempit with the car.
functions to cool the engine down

when ur engine stops, ur water pump stops... water pump stops means coolant circulation stops... water stagnant inside block water jacket still hot while radiator fan only cools down the water at ur radiator...

this helps prolong radiator lifespan as it does not get heat soak....

thats why i said get a turbo timer
set it to idle 20 min
and without thermostate and tap the fan to bypass the switch sure will cool the level below middle mark la

But it will reduce the lifespan of the motor. Normally motor ko faster than radiator.

Morning guys, gonna necro this post...

My car used to have this fan sounds after driving. (Stopped the car).. but I found the "fan moving sounds" is gone.. I open the engine hood and heard "click click/tick tick" sounds..

I'm worry that the fan has spoiled, how can I check that or inspect by myself?

Start the car and let it get to operating temperature and watch the fan

Anyways if fan broken your car would have overheated long ago

Morning pal, thanks for advise. I think maybe something else wrong as the temperature indicator is alright.

Nothing is spoiled , the fan is controlled by temperature switch , if the engine was driven hard or hot ambient temperature and suddenly switched off then the temperature is still high enough to run the fan

If not then no need to run the fan

Click click tick tick check the fan relay if it is not rurning when you switch on the aircon at normal engine temperature.

Hit the fan motor with a screwdriver if it runs then you will need to replace the fan motor. Be careful don't touch the fan blade.

Thanks for the tips, but may I know "where and how" I can look at the relay fan? My car model is suprimak s.

Knowledge learnt, thanks man.
But I'm still worry about the "click click, tick tick" sounds, maybe I'm just too.sensitive.

That's is just metal contracting all cars will have

No problem bro, i use exora bold which have the same engine with suprima. Already 4 years, its normal

Good to know this is common issue and not a big problem

It happened to my persona Sv. Super hot weather, and after short city drive and also uphill driving. The both fans ran for about 5 mins. I reckon it’s normal lol
