I think is normal. Sometimes mine around 2.5K RPM AIFM starts kicking ed.
But sometimes no "sound" at all even at 3-4K RPM. That why I think my AIFM kong ed


So early Buka meh??

Yup, Maybe AirCon as well.

But how come aircon rev during engine rev?
I know some time the aircon compressor will stop when it reached ur set point temp but for my case, the sound comes when i accelerate... Same frequency wif auto gear change

this aircon will not stop...it will just keep getting colder and colder
and i found out that...the higher u rev the colder it is
mean the faster u go...the higher the RPM...the colder the aircon

That doesnt make any sense.... Then wat is the purpose of aircon temp control if we cannot control?

well...the 1st dial...the more u turn to the right...the colder it gets
usually set to middle is the best
and this aircon...it's not that we cannot control it
it's that this aircon is no ordinary aircon...the lowest temp should be quiet cold already
but on hot day it's not enough
this aircon is not supposed to be put inside a sedan....it's meant to be put inside lorry and bus
so that's why it's so cold and also why it suck so much power from our car if we're using 1.3L(feels underpower)
1. it won't stop becuz weather is hot
2. it delays the blow...if cold enough...maybe...instead of once every 30 sec...it blow 40sec once maybe
opening it at night or rain may result your car cabin becoming a freezer

You get it wrong again...this compressor will stop after reached the set temp, and will run for few sec and stop...all compressor will act like this, there is impossible it will run continuously, becos compressor will kong faster.

The reason why you go faster the aircon more colder is because the airflow through radiator is increase during highspeed, nothing to do with ur engine speed. Try rev ur engine to max while ur car is stationary, see whether ur aircon is colder or not.

This is true...last time my old Nissan 130Y...still can jalan when the radiator fan breaks down, provided the car is moving at decent speed...once the car caught in a jam...engine temperature rise till MAX...LOL...

1. It won stop if you set it very low temp but ur car is stationary and under hot sun, simply becos ur temp can't reach the cut off point.

2. The compressor is stop, but blower won stop, it will continuous blow air inside the cabin.

Fan just for car stationary heat dissipation only.

Ya kar?

Sounds like driving a turbo car yo~~

So it is normal then?

ya, normal..

Wishing ALL our Muslim Bros "Selamat Berbuka Puasa!!"

1. Can.
2. Inform the Service Advisor. Let him/her know that you don't need it.

Whoops 16" sorry

Shiok-ness after 4000rpm.

Sound + POWAHHHH

hi, wanna know, can we claim car steering at any SC (2 months old car). my car's steering rattles when accelerate. mine is without ABS. really irritates laa.... the sound

Have the drive shaft, steering rack etc checked.

Mine iafm normally start kicking when my kmh reach 120. Is there anything we can do to minimize the sound from entering cockpit. It just to loud...

the IAFM is actually silent
there is only a sound in between switching long to short only(around 1-2 second)
it's not like a continuous sound
i think u mean the engine noise...is it?...this one need to do soundproof
