Does using the blower on a higher speed affect fuel consumption when the AC is running?

Also do you suggest I undercoat my car as I live in Karachi near to the coast. It's a Toyota Belts. Some say there is no need as its a JDM.

[Xulfiqar]

Is there some bearing inside which may cause this type of sound?

there are quite some bearings in there, this sound is usually a synchro ring running dry.

I am afraid you are on your own in this, I dont have the japanese manuals handy with me to look up that indication which looks like a print

I will try my best to find the source of this - as it is not red or orange, I dont believe its any sort of alarm.

[umairbvs]

sounds like your ECU is not seeing the A/C working, when you changed the compressor what did you do with the compressor rpm sensor wiring, it feeds back to the ECU that the A/C is running. If you bypass this then the A/C will work by rigging it but the engine speed control wont work as it does not see that you ever called for A/C

@xulfiqar bhai my citi doing the same. have replaced the compressor recently and now when a/c is turned ON the RPM dont go to a higher position. Whats the solution? rpm sensing wire is in fine condition as i used to get higher rpm in older compressor. does this mean that rpm wire is not compatible with the replaced compressor?(which is a used kabli one)

Xulfiqar bhai, i have turned Google upside down to search this Da Vinci Code I hope its not anything to be worried about.
Anyways do let me know if you come across its purpose. Many thanx.

This happend just know my father's car was missing so i removed the spark plugs and ignition coils they were soaked in oil is it something seriously bad ? the car is a Terios Kid with a Toyota Duet engine
yesterday morning i went out in the same car and noticed the heat guage was almost at H upon checking the car had no water/coolant in it so(radiator was leaking and something was apparently wrong with the fan) today the car was sent to get the radiator fixed and fan was replaced after that the car was behaving weird (missing) and it felt like one of the plug wasnt firing

LOL
The car ran alright all day after that till the next the car was handed over to get the fan replaced after that it started to act weird

This thread should renamed "Ask Xulfiqar"

I have 2 questions..

Pajero - 1993
Q 1. What is the life of a horn pin, how many kms will it last on straight roads and how many kms on winding roads?

DIY
Becharo horn stopped working, when i removed the steering wheel i saw that the pin has worn out.. I was too lazy to go Plaza and buy it, i used the head of a fuse and it works fine..

Q 2. How much kms will this metal last
Done about 8000kms and still working.

[HanifBhatti]

Reason for dirty hand in the above pic is because I changed the V belts and installed the newly serviced alternator

@Xulfiqar
Hope you are doing well
I have two plus one questions about my Kia Spectra.
Hope you can help. Thanks.

1st is, whenever I brake, my car dips from the left side [passenger side] and moves downwards, whereas right side [driver's side] remains stiff and shows marginal downward travel. When I pump the shocks of both sides one by one, by pushing on fenders, they feel fine. I didn't notice this for a long time but one day I gave my car to a fellow spectra owner and he noticed it and mentioned it to me. After that I also noticed that.
Any idea what could be the reason...?

2nd is, that whenever i lock all four wheels, car skids to left. I mean it should go straight with locked wheels, shouldn't it, but 8 out of 10 times, the front skids to left, no matter how small the skid is.

3rd problem is, my car starts to vibrate after 100km/h. When my friend was driving and I was sitting in passenger seat, I could feel it slightly to vibrate even at 80 km/h but usually when I am driving, I feel it after 100 km/h. But after 100 km/h, its very obvious, and after 120 km/h, the vibration is there but doesn't increase with speed. Interesting thing I noticed about this vibration is that it is MORE obvious when car is cruising in fifth gear. If I throttle it hard in 3rd or 4th gear, the vibration is not that apparent. I mean its there but cant be felt as bad when car is in fifth and cruising. This vibration has been with my car for a long time. I have changed several alloys, rubbers but to no avail. I also got spigot rings for the current alloys, but to be honest those made the vibration for obvious.

Now, the thing is, my car had a bad accident and banged into cement chicanes at 100+km/h from right side very long ago. That's when I started to feel 100+ km/h vibration. The workshop I got it fixed after the accident declared its due to my rims and other stupid excuses. The did change right side shock absorber, knuckle and I think lower control arm as well. Anyway, they didn't own the bad workmanship and I somehow didn't get the chance or time to sort it out with them.

I would really appreciate some help.

Regards.
Aref.

@libra

that pin has no set life, I have found that a dab of grease helps it along for about a decade or more even. btw is the fan shroud missing or did you take it off for belt service. Props to you for the fuse end usage, I would suggest find a brass or copper one.

At very first it would be wise to remove the struts and check their damping for even working, then check the springs for similarity. If your car is pulling on brakes only then the brake hydraulics are questionable, If it pulls or acts funny on bumpy roads then the strut is not damping the spring.

The fuse end was greased and fixed. About the shroud half was missing, bought a Kabli from Pindi and fixed it. Next time horn stops working , will fix a brass or copper one.

Thanks for you reply.

@Xulfiqar bhai my citi doing the same. have replaced the compressor recently and now when a/c is turned ON the RPM dont go to a higher position. Whats the solution? rpm sensing wire is in fine condition as i used to get higher rpm in older compressor. does this mean that rpm wire is not compatible with the replaced compressor?(which is a used kabli one)

if all was original and some function stopped working, best go to a proper person who can trace all the wiring. Its very common for our desi A/C cheeta mechanics to cut wires for their short cuts.

A mechanic checked the car he said that the valves are jammed due to running on CNG could this be the problem ?
And any way to clean the valves without removeing the head ?

@xulfiqar Bhai
Today I visited one of my mechanics and checked gear noise during 4th to 5th gear shift when clutch is pressed. He told me that he will open the gearbox and put a bush made by kharadiya. the sound will finish. I am confused about his approach. The noise is only felt during shift from 4th to 5th gear and back. No noise in low gear shifting.
Further he told me that clutch plate is weak. Dont know why he told me this.

@ Zulfiqar Bhai

I need help with 2 things.

I had been running a stock 4e-fte without any trouble (no issues whatsoever) until I upgraded the turbo to a Garrett GT28 .48 a/r at 8psi - Oil pump seal started leak oil, replaced the seal 3-4 times and still faced the same issue. Someone suggested that I should change the oil pump and I did so with a kabuli one and the leakage was there but a lot less than the previous oil pump - Would changing the oil pump to a brand new one resolve the issue? Is there any difference between 4e-fe and 4e-fte oil pumps?

At the moment, it is still running stock internals with a hybrid turbo (compressor & turbine of a td04h) at 10psi in a Corolla AE101 (went head to head with a 176whp charade) and have been running it like that for the past 4-6 months and it recently started burning oil (blue smoke on boost and a cloud of smoke right after boost, i'm guessing the piston rings need replacement). Since I will be redoing the engine, will it be a wise move to keep stock internals and only get the head ported and polished and match intake and exhaust manifold accordingly to the ported head. I will be replacing piston rings, do I need to get a certain head gasket to match / sustain the head porting and polishing? Anything else that may need to be looked at for this upgrade?

Thank you!

This is usually a problem of burnt valves, remove to rectify

This is not a very good approach, He most probably will make a shim for the countershaft.
