erictioh can answer your question.

read his post --> https://forum.lowyat.net/topic/1495749

iinm want upgrade braking power, need to consider change to double layer brake servo, better brake disk, better brake pad, use steel hose, better brake fluid.

use same stock single brake servo will feel no difference.

btw, what brake pad you use?

in order :
1) change better brake pads

2) change better brake disk /rotor
(better change brake pads and rotor 1 shot like TRW brake pads with TRW brake rotor)
some say change brake pad and rotor still same & no difference, so process with :

3) change to steel braided brake hose

4) change to better brake fluid
if enough, can stop here. if still nt enough

5) change to double layer brake servo

not sure about persona, but i have experience with clogged cowl drain (the windscreen drain) with my saga. the cowl drain very much clogged up until each time heavy rain, the water overflowed and leaked inside the cabin front passenger side.

when my car send to workshop and perform the rain test simulation,only then can pinpoint the culprit is the clogged cowl drain.

cowl drain is easily clogged for cars always park outside, and under trees.

so i suspect you have clogged cowl drain issue but not fully clogged drain like mine. so i suggest you go check the cowl drain

workshop at PJ.

actually, if you calculated it manually based on your data, you should get 6.11L/100km or 16.38km/L. the highway driving helped alot.

because rm50 only 24L.
persona tank is big, you sked to use until 40L pump petrol full tank.

even with 14km/L, use 40L petrol also can reach 560km mileage. but need to pay petrol rm83.20.

same fc, rm50 = 24.03L * 14km/L = 336km

make sense, right?

6.7l/100km = 14.92km/l
14.92 * 24.03 = 359km
14.92 * 42L (until fuel blink) = 626km

that is why our friend can reach perlis from melaka. (provided maintain 14.92km/L or 6.7l/100km)

get 14-15km/L for a proton car is good enough, but it's 100% driving so nothing to shout about really.

but if comparing highway driving with a 1.3L 4at saga and persona 1.6oL is a high difference. so you should be very proud of your persona. e.g saga petrol blink from kl max reach gurun.
persona from kl easily reach perlis one shot.

yes, this the best choice.

only after comparing with the manual recording can know whether the meter indication is accurate or not.

example from ckdenion himself : http://www.fuelly.com/car/proton/inspira/2...ckdenion/335829

iinm around rm70 with labour

since 5 years already, even-though low mileage 65k, did not reach 80k yet, i suggest to replace the timing belt.

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.

might as well visit workshop to diagnose.

can use special power steering fluid or ATF fluid.

iinm referring to my proton saga IF use ATF fluid, use around 1L (use actual around 0.5L)

gearbox oil use 4.25L, from 5 bottles, 4.25L for gearbox, then the rest i told mech to change power steering fluid using the balance. after change also got little balance.

no experience for person though.

so roughly, change gearbox oil (usually 40K change , change 1 shot power steering)

p/s: i buy ATF fluid outside, so just pay for labour (gear box & power steering fluid change around rm30-40 i guess)

more than enough.

proton also use atf sp3.
the answer is yes.

for me, i think you should consider change the seal because like you said, dust will easily getting inside the cover and accumulate the timing belt. dust and oil is timing belt worse enemy.

based on my proton saga, you can diy open the cover and change the seal. what i need for my car is only spanar no. 8 (of i not mistaken) i think same for persona.

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.

that is what i tipu my self when think twice thrice about soundproof my saga. ok la no bad la NVh, until one day got money, not to change car for a long time, already fedup so ok lah do 1 shot lah.

still bad for me. since i know the diiference. this is the problem once you venture into car soundproofing. curse my jibai noobness.

maybe because old saga and old persona diiference design, suspension etc. this is what i and my fellow friend debate since we both do full soundproof on our car.

if i were you, at least i do the door soundproof la. the milo tin closing door sound annoys me.

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.

iinm that is market price @ car dealer price.

if want sell direct buyer should lower the price. if not, would be hard time finding buyer. maybe if 12-13k maybe can get buyer easy.

that's how it works, like it or not.
