Since when is the last time you changed transmission oil ? And any recent clutch adjustment or repair history?

Transmission oil has never been changed. And no repairing of clutch or anything...

Check the transmission oil level and see if it needs to be changed. It should not be brown or black. And change the fluid once in a year atleast.

Oka. I am on it.
Next question? May I ? Lol

So i have a santro its left wheel kinda resonates at certain speeds errmm like a noise 'Ghoooonnnn Ghoooonnn' - i think we can call it resonance. I guess i have a shorted bearing please courtesy us your expert opinion..
(To save time) if its shorted the procedure to install a new one is as easy as going to latte shop and ask him to remove the existing one and press the new one? Right?

A bump and
Feedback on Air Conditioner charging.

So i vaccumed the system upto -29 mmhg read you saying that a while ago and ran the pump for 30 miniutes then stoped it for 20 miniutes extra to see if vacume drops and there is a leak or not. It didnt. Then pulled R22 charge sheet from internet and started charging the gas according to that air temp vs pressures sheet.
And its been a day and a night the system is On. That friend called me last night and said yawr its even more chilling than our new AC we baught two months ago lol (and rest was his makhan-policy stuff to cover the fact he didn't pay for the gas LOL)
Thankyou so much @xulfiqar bhai it would have never been possible without you.

@xulfiqar
Bhai your word about the suspectedly bad wheel bearing??

[Driver41]

My mechanic suggested to replace brake discs/rotors of my khyber 99. I did some search and found that minimum thickness should be 8.0 mm (on this website http://www.acdelco.com.au/PDFs/Catalogue_ACDelco_Rotors.pdf )

Is it correct? Seems like my rotors are of 7.0mm. Shall I change them?

Any recommended brand?

There is corrosion on edge of one rotor from which there is squeal sound upon applying brakes.

Zulfiqar......

Bro i want to know where to find the engine number on 2C diesel engine. I hav an indus corolla wid 2c engine, but dont know where to locate its number......

bump....

[Xulfiqar]

bump....

in typical old toyota fashion look near the tail of the engine on the block, you will find a flat machined surface, the number is stamped there.

[afnan.bashir]

@Xulfiqar @ser_gtr can we test the compressor once the pipes are disconnected. Mechanics here do that they put oil and try to block the outlet. If it produces pressure they say it is fit.

In my current scenario gauges are not good for diagnosis as pressure after condenser is low (not checked but pipe is little warm and before condenser it is super hot)

I bought Chinese Condenser (RS 3500) and DENSO Genuine TXV (RS 2300). So called Denso ND oil is 300 for 40cc expensive. Any other good brands of oil and R134?

Bro wat is tail of an engine??? I m totally new to this auto business.... Sorry for asking again and again but from ur posts i hav gathered that u r an expert at 2C diesel... can u help me wid some pics??? thanks bro

[greyhound]

this is pic of my car's engine. Where to find that engine number???

How Can You Justify And Guess Pressure By Putting Finger On Compressor Outlet...They Might Have Pressure Gauges On Their Fingers...We Don't Have...A Weak Compressor Will Produce Enough Pressure Also To Feel By That Method...Only A Fully FARIGH Compressor WILL NOT

Use ND Oil As Recommended....Any Other Oil Might Not Come Be Compatible And Everything Will Be On Risk For Just 1k Or So Amount... So Don't Take Risk

For Chinese Condenser..They Are Available Only So YES If They Have Good Heat Exchange ..Then They Will Work And I Guess They DO Work....Better Than Blocked Choked Condensers At least

[wasim625]

@ser_gtr has the point

Well I am in agreement there but thing is if condenser is blocked it won't make pressure after it and schader valve is after condenser. problem is still there how to test compressor in my scenario where gauge won't help much. Even it shows low pressure then one can't 've sure
