Using Total quartz from authentic pumps..

[nfssaad]

i had a 12volt diaphragm type fuel pump lying around.

used it as a vaccum pump.

sucked most of the dirty oil out of the brake reservoir bottle, filled with new.

then went to each tyre and sucked the oil from bleeder valve, kept topping up the brake reservoir bottle.

worked fine.

Pressure is better than vacuum

after you have drained sump and replaced filter and also filled the lost oil in sump - follow this method

get a light colour container and mark it in liters - now find some clear pipe that can fit on the cooler return line to direct it into said light colour container.

start engine - let the oil flow into container - about 2 or 3 litresstop engine - fill equal amount of new ATF that you drained into gearbox.start engine - let the oil flow into container - about 2 or 3 litres.stop engine - fill equal amount of new ATF into gearbox.

repeat till you see brand new ATF being pumped through the cooler line, This will happen usually at 80 or 90% ATF capacity of your vehicle. - meaning if your truck takes 13 litres of ATF, you will see clean ATF by about 11 or 12 litres.

The idea is to keep the sump full of ATF, disconnect the return line so old ATF cannot mix with the new ATF in sump - the cooler line to the radiator is always from the torque converter exhaust.

All ATF from sump is being pumped through the oil pump -> torque converter -> radiator -> sump. - We just intercept it at the last leg and fill with new.

This is the exact method what I was looking for.

Thank you so much.

This morning I had a general look in the engine bay, but frankly I couldn’t find the ATF Coolar Radiator or lines.

But it was just a quick look before leaving for office. Will have a detail look on it today again.

Nevertheless, thank you once again.

@Xulfiqar salam sir. I would like to ask about your opinion regarding 9th generation altis 1.8 (2005-7). Generally it's a perception that 9th generation corollas have pathetic brakes and control. Does it also applies to altis given that it has abs.

Also it engine consumes oil. Is that fixable easily or we have to live with it. Is there any other known issues in this variant and what's your overall opinion about it for using it as the only family car for daily driver and long routes.

Dear Xulfiqar
My daewoo with G15MF engine fitted with 3 speed auto transmission i need to release the gas pedal at 3-4k RPM to shift from first gear to second and from 2nd to 3rd is this normal or i need to worry about? or i need to change the oil? or something else?

[Xulfiqar]

your vacuum modulator is dead. Replace it with a new part

[overspeed111]

Sir thanks a lot, it will be a hard to find this part here as automatics (hydramatic) daewoos are very rare over here, cleaning DIY of vacuum modulator can do the job if i cant find replacement?

[obt.2009]

@Xulfiqar Bhai, need your advice for my Indus Corolla 99. where can i find a good mechanic for tuning?
my car sometimes give 12 km/ltr average and some time it gives 6-7km/ltr.
also i have witnessed sometimes (not on regular basis) there is a blue smoke coming out from the exhaust.Although got its ring piston changed last months but issue is not resolved yet.

Also i think engine is buring oil too. there is no leakage in the engine room.

sir today i did the DIY and get to know that vacuum modulator is inside gear box cant be replaced from outside seems like a hefty task to do this and also i do not have expertise to open a auto transmission, i ve replaced the vacuum pipe and sprayed carb cleaner but yet no effect on that.
thanks for your guidance.

@Xulfiqar

Salam. I have purchased Suzuki Cultus 07 Carby model. The car is above 1 lac but the meter says 68k. The engine is fine. No major work required on it. I will only change all the oils, spark plugs and clean the radiator.

I have drived it for a week and I think the engine has not a great fuel average. Should I change the air and fuel filters for this purpose?

I also need to ask that which engine oil will be best for my car in winter and in summer.

I am really confused. Some guys say to use 20w50 as the engine is old while some suggest 10w40.

Please suggest me the best engine oil.

@Xulfiqar

Salam brother. I have Civic 1999 vti. In december the engine blown up due to heat up. this was the 2nd time. I swapped the factory fitted D16y8 with the D15B. swapped just the assembly. all other items I used are of D16y8 like Manifold, sensors, throttle body etc.

I'm facing the issue of unstable RPM. it goes to 1100-1200 then drops to 0. many times engine shutdowns. I've changed the autochok but in vein. Can you please help me in this regard. or you can suggest a good mechanic (not thug) in Lahore who can resolve the issue. Thanks.
