Dear boss joey, can i seek your advice please? Will you know what is the reason why my car feels sluggish when driving on a hot day? I am currently on RISK & FDL. I also switched on my aircon but compared to switching on aircon at night, the nightime sluggishness is not so obvious. On a hot day, my car realy feels sluggish. Can advise me? Thanks. Picanyeo is correct. I can minimise this different but the means your cool day power will drop.

Hi joey... so far there seems to be no negative effect other then the noise... will this cause any permanent damage if I leave it..??

Hi Joey, can I ask, when I make full turn / full u turn (either left or right), there is a "Eeee" - like rubber grinding sound. But if I off aircon, and make full turn / full u turn (either left or right), no sound at all. What could be the cause? Repair quote?
And to add on, it does not have any sound at all when I drive straight or making turn....even when on aircon. Oni make full turn / u turn have sound when aircon on.
Mine is 2006, maunal picanto and this happen only after I change my whole clutch kit.

Hi Joey,
Like to check if there's anything wrong with this:
Normal battery voltage when idling: 13.8 to 14.0V Rpm when idling: 630rpm average
When aircon cuts in (with the magnetic clutch noise), all remains normal.
When the fan cuts in,voltage drops to 12.5V. Idling drops to 570rpm. Vehicle experience vibration and dimming of headlamps. This happens for about 5 secs before rpm and voltage is adjusted to higher levels.
Is everything normal for this situation?
Thanks.

Thanks. compressor turned on, rpm drop, ecu compensate to reach idle rpm again.... air con radiator fan kick in, voltage drop..... normally ecu compensate without letting the engine die unless you run big turbo with low rpm idle value 650 +/- sure die HAHAHA.... off aircon release stress on engine if you running on small motor, big motor > 2.0l rpm drop hardly noticeable

Hi,
Driving a Cerato Forte 1.6 with 17inch tyres. No modification except H&N Air filter instead of stock
My last 3 FC is 10.2KM/L , 8.0KM/L and 8.2KM/L..

Any idea on the weak mileage? 10 km/l is really bad for 1.6l engine. Advice you go harmony motor and check. Mileage depends on driving habits, have you change the way you put foot on the acclerator recently? Have you change the type of patrol use in your car for example ron95 to ron92? When did you last service your car, has the engine oil been change base on interval ?e.g. every 10k Is your tires having the right amount of air? When did you last check your tires? When did you start to realise the drop in FC, if its after using aftermarket air filter than change back OEM to see if it improves your cars FC. K&N air filter is an oil base cotton filtration method. Maybe its messing around with your sensors which normally throw a CEL (check engine light). But rarely happen. The best is to bring to harmony workshop to check

To be exact, my mileage has always been 8km/l - 10 km/l since I got it second-hand in March 13. It is a 3 years old car, and serviced once around March.
Seems to be too early for my next servicing which should be due around August.

Hmm.. 8km/ltr to 10km/ltr seems too low for a forte. I don't know the exact figures but I think it should be higher. You can follow wjhr89's suggestion and do some checks. Another thing is how's your driving style? Heavy footed?
Your 17" rims is the stock rims?

Depends on whats inside the car and what petrol used also. My rio gets better km for ron98 but its more ex also. And the driver is so heavy that fc is 9kpl vs norm of 13kpl.
Sent from my GT-P6200 using proboards

I seldom get pass 3000 RPM , consider normal driving..
17inch Rims should be aftermarket , not sure what brand though. Petrol use ron95..
Haven check amount of air in types yet..
Not sure cause the FC to be so low, think need to bring harmony motors to check for my nxt servicing..

Hmm.. Everything seems normal... Best is to bring it for a check. The low FC is unlikely if you are a light footer as well.

Joey, if my wheel brake cylinder is leaking fluid, does it mean I got to change the master brake pump? Or can I just change the wheel brake cylinder? how much would it cost roughly?

Actually my cousin's Forte (AT) is around these figures BUT he did some sound proofing... think added another 8-9kg? But yeah. he was lamenting it's around 9ish... which was what I was getting on my 1.4AT Rio

I think have to compare the general population of 1.6AT as a whole. If everyone gets 9+km/ltr, then probably it was meant to be this figure.
I would expect it to be 10+km/ltr. Can't underestimate that 1km/ltr. It means you travel 55km lesser per tank, which in turns turns out to be 220km in another assuming you pumped on a weekly basis.

Not sure cause the FC to be so low, think need to bring harmony motors to check for my nxt servicing.. I read that there may be some sort of fuel tank level feature installed. It's called fuel tank differential pressure sensor. I don't really understand how it works but I know the engine is generally more responsive and powerful when it's more than half empty. As the fuel level drops beyond the half tank mark, somehow or rather, the engine performance drops. The further it drops, the worse it gets. But it maximize the usage of petrol though. I do notice a slight improvement in fuel consumption when pumping petrol when low fuel indicator is activated or almost activated. Won't be really significant. For me is about 0.8km/ltr increase. In good times, can get more than 1km/ltr but rarely. So you may want to try pumping at low fuel indicator to see if there's any difference if you have not done so. No harm trying.

You can only slow down the deterioration by using good engine oil and do on time or earlier service. Add Lifter Additive if you want.

There are 2 possibilities: Worn out Power Steering Pump (no cure, only change) or "High Blood Pressure" narrowing of Power Steering High Pressure Hose (no cure, only change). Thanks

This is a common problem with Mitsubishi family of vehicle (which include earlier Hyundai and Proton). For E-throttle version, first clean up the Throttlebody to see if the problem solved. If not there is no much else can be done except improving the efficiency of the Alternator (smaller pulley for higher RPM or higher power Alternator). Improve grounding cable can improve this situation too.

Not sure cause the FC to be so low, think need to bring harmony motors to check for my nxt servicing.. I agree with all the Bros here that the FC seems to be on the high side. I would suggest that you do a thorough de-carbon on the Lubrication, Fuel and Air Tracks to begin with. And monitor from there.

I think I'll leave it for now.

Hi Joey, I'm currently facing a issue, whenever I turn my steering wheel to the right, close to a full lock, be it moving forward or reversing, I will hear a clunk/click noise from the frontal left. could it be the cv joint? thanks in advance.

Just like to enquire, if we use the power socket in the cabin for extended periods of time eg. Car camera, GPS, will there be any adverse effects?

Hi joey, how much is it to change to a re-con or new radiator?? my ride is a 04 cerato... found my radiator leaking from a few fine cracks near the big rubber hose which connects to the engine (might be the long plastic part which many bros here talk about).
regards
