@Xulfiqar i was diagnosing a clunk noise from front left side of my car. Happens when you put from reverse to forward and start moving and also happens on speed breakers or bumps. How to diagnose. Secondly If i remember correctly when we install bushing in control arms and wishbones etc we have to tighten them after getting them on wheels rite? this can be done by lifting hub by jack rite?

yes - you lift the hub with a jack till the weight of the car is supported by the jack, tighten down the bolts in this position.

And what about cluncking noise? on bumps and reverse to start once?

Anyone?

Hi guys! I have a suzuki fx 1988! I was planning a trip to pindi so i was thinking to take it.. As it is hot so i will also be using ac... Can anyone guide me what should be my speed, how often should i stop it for rest and for how long? What precautionary measures should i take?
(P.s i will be travelling from lahore and will be using motorway.. One more thing that i recently changed its head gaskit)

This question is really a driver experience one, e.g. if the car is operating ok, why stop to waste time, I would however suggest you stop when you are tired too - suzuki FX wears out the driver like a boxing match. you will need some rest every 3 hours in it.

@Xulfiqar may I get your opinion regarding my question in post no 6370?

Dear Xulfiqar sahib

I intend to do brake fluid change on my 1.5 years old Suzuki wagonr, for that I have ordered zic dot 3 brake fluid from zicoil.pk and this is what I received:

Now the physical appearance of the containers suggests that they have been stocked for a significant amount of time, there is no MFG/Packaging date on the container so I observed the color of the fluid and benchmarked it against others which u can see in the photo.

Guard is bought from metro 3 months ago, it does not have MFG date but is very light in color.
Quick is bought from local shop few days ago, it was manufactured in March 2014 which is indicated by its color.
Last is zic which is darker then guard and lighter then quick so I assume that it is sitting in the container for well over a year.

So my question is does brake fluid absorb moisture in a sealed plastic container over time and become useless? or its just me being overly paranoid and it is absolutely fine to put it in my car regardless of its color out of the box. Apparently fluid in my master cylinder reservoir is somewhat lighter than zic.

Your expert opinion is opinion is requested.

Thank you

the colour of new fluid from sealed containers are meaningless. As long as the containers were sealed up right before use, they are good for service.

Dear Xulfiqar,

Can you please look my post 6362.

@Xulfiqar,

Ive installed inline fuel pump(CRLF) on engine bay about a month ago on my carby cultus. But from almost 1st day Ive continuous problem of shutting off my car engine after 2,3 miles or sometimes more while accelerating(no only on high speed) and won't start again on Petrol until converts on CNG but later after some time(minutes) it starts on Petrol . My mechanic already checked fuel filter, Fuel lines. He thought that might be issue occurs just because of intank fuel pump(although not running) hindering fuel flow. But for me I think its bc of just bad inlne fuel pump(although I can hear its sound all the time) due to its winding which stops working while hot. On other hand car runs fine on CNG.

Ive installed this pump for easy removal and installation in future. Also due to full fuel tank.

I need your valuable advise and troubleshooting on whether it just because of bad fuel pump, carburetor or due to some other thing.

Jazakallah

And what about cluncking noise? on bumps and reverse to start once?

check anti roll bar bushings and also check the axles.

Sir i ve searched scrap market now the scenario is that manual conversion is costing me 25k and whole 1SZ vitz with manual trans is costing me 45k (3k lower if i opt for auto) , and similar MX 17 gearbox is not available in the market, engine health is like i ve replaced rings a year back and the block and pistons were in good condition but it does gives smoke on startup as the lathe worker didn't replaced valves only replaced seals of valves he ripped me of as the valves were cut so hopefully it will require work again, if i go for similar auto box which box will fit easily that carby cultus engine without changing axles ?
ever since im rubbing my head on what to do as im really confused, please help me with this my ultimate dilemma.

trans gives karr karrr like sound on parking if i press accelerator and the car is parked since problem arises 2 weeks ago
and the car dancing problem on sideways is not solved yet please advice me what to do.

sir please answer my query.
thank you

Would flushing ATF help resolve torque converter shudder ?

Dear Xulfiqar,

Can you please look my post 6362.

The intank fuel pump in your car is a pretty robust item. Usually doesnt go bad unless you run the car out of petrol. If this were my car I would remove this aftermarket pump and buy a new genuine intank pump.

Thanks @xulfiqar

But my problem is that fuel tank is almost full and don't know how to empty fuel tank?. Where as I changed intank fuel pump with kabli one (almost looks new) in late 2014 with installation of cut off relay and used initially for some time but then didn't and after almost 1 year when I cleaned my tank considered fuel gone bad and refilled the tankbut surprised to see no fuel pump out from tank. One thing if you tell me, Are you sure there isn't any issue with the carb or any thing I would do to make sure that only fuel pump is the culprit.
