Outstation fellow like me feel so outcasted LOL

Jalan PUJ 3/2, TK Aircon Service. Nearby the clinic Qualitas, right beside Panasonic car battery.
I just passed by there but there is a property agent banner hanging on its shop. Maybe sudah bankrupt.

so i buka the fan blower, wash the fan fins. buka the mesh filter and brush with toothbrush.
now ac fan blower is stronger, morning feels cold with compressor on-off in healthy interval. but comes noon fetching people will still feel the coldness inadequate. 1 thing i observed is when the car stop in traffic, ac will not cold. when start jalan the ac will be colder. i don't think is radiator fan as the radiator fan noise is still loud and audible. so was it compressor weaken?

Sounds like your condenser not dissipating heat as good as before already. I heard from mechanic if your air cond turns cold when you spray water on condenser unit, it's the condenser problem.

Anyway on servocing air-conditioning system it's controversial.. Some advocate service it with a certain mileage or time frame. Some others said that it's a closed system thus do not need service until it malfunction. I don't really know which one is the correct way of doing it.

Persona IAFM has two fans up front, the smaller fan next to the radiator fan is for the AC, check if that one is spinning when AC is engaged.

Also even if the fan is spinning also doesn't mean it is spinning fast enough.

Your symptoms sound like the AC fan in front kong or losing power.

he should go aircond workshop do inspection.

according to 1 aircond specialist i follow FB :

you should start learn about aircond servicing.

from source below, you will learn that aircond servicing is not just cleaning only, but also replacing parts, such as receiver drier and expansion valve.

yes, it's a closed system, so meaning if aircond not cold, it means gas leaking somewhere. no need ask topup gas because already leaking what for topup.
why need service? because inside airocnd got oil for compressor to work smoothly. when you neglect service, oil become bad, and make it clogged then it tends to leak. worse it you will forcing the compressor to work harder until one day it will be rosaked. see video understand more. i ask you simple question, why you change engine oil, power steering oil, brake oil, radiator coolant, gearbox fluid etc when you say it's a closed system? hope i make you clarify about it.

p/s: i am noob non-car guy but i already experienced repairing my aircond, so gain extra jibai noob knowledge about aircond servicing.

my other source is LYN member @cheelam who got car aircond service

Yeah it makes sense... Might need to go to my air cond guy soon.

4 Litres of engine oil becomes 1 litre plus left over only...
5W-30 full synthetic oil really can't use in our hot country here?

Not the weather. It's either your engine consume oil already, or campro not for this viscosity.

i tried 10W30.. engine is louder

what is your car mileage? very high mileage is it? or maybe your oil sump bocor?
used 5w30 fully-syn on my car before, don't have engine oil reduction. engine become happy-revving always easily shoot to higher rpm.

I even use 0W before, all seems okay.
Until recently.

around 168k, not sure consider high mileage or not.

Ya, all the while using 0W & 10W Full syn and the acceleration really nice...

Check anywhere leaking engine oil

OK let me set this engine oil debacle straight once and for all. It has cropped up too many times.


Engine oil u buy in Malaysia are called multigrade oil. such as 0W-30, 5W-40, 15W-50 etc. Multi grade means the viscosity of the engine oil changes according to temperature.
The 'W' in the front part of the oil specs means WINTER grade. It is TOTALLY IRRELEVANT[SIZE=7] in malaysia as our ambient temp never go lower than 25Celcius.
Why not sell single grade oil in Malaysia then? Well its because economic of scale blah blah blah..

Multigrade oil flows EASIER in lower temps and gets more vicious/slower flow rate or in layman term 'THICKER' when engine reaches optimal operating temp.
The 30/40/50 is the thickness of the engine oil during operating temp. When engine are designed, the moving parts have a certain need for tolerance. The oil is then there to fill in the gap in the moving parts to lubricate it.
Older gen/high powered/high cylinder count engines GENERALLY requires higher viscosity oil. Campro are designed for a minimum 40 grade oil, but recommended in owners booklet is 50 grade.
Running lower viscosity oil makes the engine feels lighter because of thinner oil film between moving parts hence lower resistance, BUT downside is accelerated engine wear and tear. The moving parts wear down more often and end up the tolerance or the gap between moving parts increases and the thin oil film wont be able to provide a good layer of protection.

A THINNER OIL FILM also means the amount of oil is lesser, hence lower amount of heat generated from the friction is able to transfer away from the moving parts into the engine oil. Hence the common misconception that thinner oil doesnt work in hot weather. Bezza, Axia, Civic 1.5 turbo are common examples of engine able to run 0W-20, 5W-20 engine oil without fail in Malaysia BECAUSE the engine was designed for it.

Engine oil consumption issue is either due to engine oil leaking out from the seals and/or piston walls. So if u dont see oil drips on ur block or floor when the car is stationary, then the engine oil u are using is too 'THIN' for your car which has a high mileage and u need to move up to 40 grade oil. If it continues to consume oil even at 40, move up to 50 grade. If it still makan oil, then gg liao go for engine rebuild.

FYI my car is more than 200k mileage yet im able to use 0W-40 Fully syn oil for my engine. There is no such thing as old cars cant use Fully Syn oil, its just the grade that matters. A fully syn is always superior than Semi syn at the same grade. Is there a difference between 0W40 and 5W40 and 10W40? Yes there is, it affects the Viscosity change Index of the oil. There are slight difference between these oils eventhough its 40 grade oil. But its just too advance if ur car is stock and just meant for daily use.

To recommend a brand, I highly suggest using Castrol. Their oils are one of the best in the market. I use Castrol Edge Professional 0W-40.
If u feel ur engine has a bit gunk build up and want to clean it up, use mineral oil like Castrol GTX and change it around 60% of its lifespan (3000km) or use semi syn and change every 5k km. It is more effective than using engine flush which tends to be more expensive and u are able to maintain engine at optimum performance.

I am havig difficulties of starting my car sometimes. I need to crank 3 to 4 times before the car can start.. Sometimes the car can start at first crank. What's the problem ya ? I dont think it's battery issue btw. Could it be starter problem ? What's the cost to repair and replace ya ?

Crank angle sensor getting faulty, or your spark plugs is quite old, or your coil plugs is faulty, or could be just your fuel pump getting weak.

Huh, it takes me 5 minutes to read all.
Very informative, bro. Thanks.

spark plug changed not too long ago... coil plug checked last month , no problem. fuel filter changed half years ago. so it's crank sensor problem ?
