is it because of your new absorber?

really?? because i also driving SE... but i dont have prob with this though >.<

lower down the speed when going through those potholes helps. i usually going through bump <20kmph depending on the bump..

con job mostly

The ones that can really do the job well will be worth the money. Erictioh's (forum member) voltage stabiliser is not bad. If you have the cash to spare, ea autowork's Impulse is a must have.

You cannot eliminate the dimming or underpower feeling on the persona though. Air cond compressor takes too much power.

Can buy first then transfer to your future car

Suppose it's ATF SP3, not the Dexron3. It has some differences in Friction Modifier between these 2.
I guess the Type 4 you mentioned is for Toyota T-IV? Definitely not worth to try, we dunno the long term side effect.
If the ATF is Universal Synthetic/Multi Vehicle type, with SP3 stated in compatibility table, then can try.

Water pump at alternate timing belt changes. Apart from that some sc will say belt tensioner no need change but from my experience that will spoil not long after timing belt due.. If got money better change lo..

Alternator part I cannot be sure. Sounds like alternator failing.

yes... only got 2 belt... timing and fan

can we use 5w40 fully synthetic on persona ? I heard many said that the recommended engine oil is 10w40....

Battery about to kaput?

Could it be starter? I really have no idea bro.. So sorry for not being able to help.

If your car is auto transmission, switch gear from P to N and push back to P. Then try start the car.

Does Persona have auto gearbox filter?

I've read the old posts in this group and many said no

But by googling it there's actually one inside the gearbox. Do we need to change it?

Not necessary. Need to check first if your engine oil is leaking into coolant tank. Easiest way to check is to open radiator cap and wipe ur finger around the inside of there is some brownish buildup. Water pump only fails if there is too much gunk around the fan blade area or the shaft breaks.
Anyways its only RM70 each. Recommended aftermarket brand to use is GMB.
Yes there is. but to replace it you would need to dismantle ur whole gearbox to get to it. Would suggest doing that every 250k km as a preventive maintenance. Consider doing a mini overhaul for ur gearbox. Price around 1k.
common issues. the wire inside that plastic hose thing on the left of the boot putus. Simple RM30 can kautim in accessory shop. they will pull a new wire for u.
Common issue to come from aircon vent, especially during cold weather or night u will hear the rattle even more prominently. power window frames rattle due to the support bar nut inside the door has became loose. just take off ur door panel and retighten all nuts.
Check your crank angle sensor. Most likely kaput or wire near putus.
