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...

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 !

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
