Dear Sir with great respect, how can you say that ZIC is also providing FAKE coolant ?
I have been using zic coolant in my ride from last year & its going strong till now after almost 40k kilometers.

Remember to mix 50-50 distilled water not tap water with caltex coolant.

[humayun.chughtai.7]

Oh thats a bad luck ! Although I have 2001 vitz 1.3 with 497k kilometets on odo. It was also running on tap water by previous owner, last year in december when I took its possession, I just flushed the coolant system for like 2 to 3 times with plain water, & there was a slight rust build up which vanished up after flushing. Then poured 4 litres of ZIC coolant.
Alhamdolillah it didn't even decreased a drop till now. I also did 2 road trips to northern areas in the same car, once to Swat, Kalam side & other to Naran side till Babusar. And a various trips to my local area hill station Fort Munro.
Fully Satisfied Alhamdolillah !

I once did freezing test on zic coolant and it survived in my freezer for good 12 hour (didnt freeze)

CNG Service ap kon se city me dhond rahey ho? Karachi mey?

[brownrose78]

AoA,
My friend took these snaps while filling CNG in his car, Outside night temperature was 25-27 degree but on CNG Machine, it detected 42 degree
Nextnday outside night temperature was 26-27 degree but on CNG Machine, it detected 45 degree
Also CNG Cylinder bar is showing Almost Fill however there was some space left in Cylinder almost More cng could be filled of amount Rs. 150-200

Which temperature this CNG machine is referring? Is it of Cylinder internal temperature?

He asked my suggestion about this issue. I think high temperature could be due to impurities(like Oil in cylinder)

Can it be due to any other problem/reason?

[humayun.chughtai.7]

I think this temperature refers to cylinder's internal temperature, bcz after refilling if you touch the CNG cylinder, you will feel it very hot.
Just my wild guess !

Dear Xulifiqar,
I've recently purchased GLI 2013, ODO shows approx 35,000 kms. However, engine start sound is like starting a Diesel engine. What could be the reason and how to get a noiseless engine? I drive well but not an expert in mechanical knowledge. Kindly recommend solution or guide me to a reliable mechanic. Thanks.

The GLi 2NZ-FE engine does sound like a tractor engine.

Even on youtube you can search the 2NZ-FE and can come across videos of the engine used in European Toyota Yaris. You can compare the sound of those with that of your car.

Any other replies welcome..

[tmalik]

Brother. Please go for toyota original coolant. Lasts a long time without giving problems. Go to the toyota dealership and get it done from them. Its a once in few years job.

You can request that you want to go in their work area to examine the work yourself. They should normally honor the request and take you to your car when its being worked upon.

[trouble_maker]

You must be using 20w-50 oil in it?

[m.shaikh]

xulfiqar bhai I am a big fan of yours. Thanks for your knowledgeable advice to all pakwheelers, great job.

[humayun.chughtai.7]

No not at all, there must be some problem with his car otherwise 2nz is very smooth & quiet engine.
Although in youtube videos, when they took the mic closer to any running engine, it sounds heavy like that. It doesn't means that 2nz sounds like a tractor.

[humayun.chughtai.7]

Dear kindly get your car engine checked thoroughly by any reputable mechanic. And only 35k kilometers on a 2013 GLI is kind of impossible thing, its surely reversed.
Are u driving it on CNG ? Bcz on CNG ECU varies engine timings & engine sounds little bit noisy.

[m.shaikh]

Needs information from pakwheel experts, is cultus vxr 2005 has an interference engine or non-interference engine?

[saboor73]

G10a is Non interferences I had broke timing belt on it once
