the same symptom happened to my friend's persona, the radiator is leaking and fan keep running due to overheating.

same thing with my yr 2011, happened since last year, after driving under hot sun, fan sure running after off engine for 10-15 mins, sometime got 2nd round for another few minutes. temp remain constant at normal level though, radiator i check still full with coolant, send to sc, unable to detect anything. SC advisor said quite normal but i think is a lame excuse from him la.  still havent solve till now

check radiator coolant. check radiator, etc.

if it's relay problem, usually fan will spin non stop until battery kaput cannot start the car.
you case is still ok.

Boss, when the engine is cold, open your radiator cap (not spare tank), try pour in coolant/distilled water, you may surprised you need to fill-up another 300ml to make it full.

I suspect your radiator is only 3/4 filled due to air-lock inside. When you replace coolant/change water pump outside, many technician don't know our car need to do air bleeding.

Check the thermostat. If the thermostat KO, you'll see the temperature rise more than half when the car is idle.
But when moving, it's okay.

Since the water pump is powered by the engine, faster you go, the air pressure will push open the valves.

Replaced mine recently for 2009 car 

I had this problem when my radiator is leaking coolant , it means the cooling system is not that efficient. After changing new radiator, never had such problem already.

So hv u solved ur problem ? If radiator ok, might be other probs , changed before the water pump ?

iinm door wind noise need to do the door seal rather than do door soundproof.

door soundproofing is for reduce traffic noise, become solid, not like milo tin. and also beneficial when install speakers at doors.

and also 4 doors are not enough actually. i think you need to do full soundproof.
what is your expectations to reduce noise and what area you did is not the same.

that is why you can say money is wasted.

look back at your car, you want feel car soundproof but you only cover 4 doors only. what logic is that.

need to see again what kind of noise you want to cover then start from there.

i tell you, persona is as terrible NVH just like before my saga did full soundproof, when i sit inside my company car persona, eventhough it use CC5 tyres.

previously i sat inside my friend's saga sv, and owh man, the same annoying noise i felt with my car before do full soundproof.

if you plan to keep your car for a long time, it good to do full soundproof because persona is a good car.

full car soundproof

including 4 doors, front hood, front fender, front wheel, full flooring, rear boot, roof.

but usually if what to soundproof, will ask, what kind of annoy are you or how annoy are you with traffic noise, road noise.

you can consult such as Mahihi Soundproofing or EA Autoworks but i recommend Mahihi because he is a member from Saga thread.

If direct owner, can my car go 16-17k? 2012 high spec meage 110k.

Engine have some leaking bt will fix it before sell off

the first battery was century provided by factory of course for 3 years, then use century again and it last me more than 2 years. Changed to yokohama for 2 years plus and some random china battery which last check no longer giving much power.

Is century still good? heard many say no longer as good as it used to be. how about Amaron?

any bro here tried TRW rotor? any reviews?

Im using Brembo normal rotor, work well with brembo brake pad. squeezing sound after changed other brand brake pad.

wow ur radiator got prob? u didnt know ur car overheated?

if temp max bar gone case already.

OMG, 2 months back my radiator prob, temp almost reach Max, how to know ur gasket edi gone? what symptoms ya?

then now engine cannot start? I overheated few times red line (fan kaput, radiator water low) but very fast I noticed and off engine. Engine still can run now.

ur engine overheated run for how long? slow traffic or on highway? if on highway the air will cool the engine right.
