I am facing a problem. I have Rkr with 1KZ . It don’t start on first attempt and mostly I have to give it heater directly by placing one side of wire on battery and other side on the small nuts of heater. Is the heater not working which causes a delay in start or it can be due to the low battery ?

Could be heater timer is non functional

I am using Attock G-11 pump's petrol throughout. Will try to change the pump to F-6 total. The thing is that the noise is not too loud and annoying but on a safer side wanted to know that it is not dangerous or harmful for engine after sometime

Drove a honda vezel 2015 last night. Car has done 165k. The car when traveling on highway, after braking and coming down to 40-50 the car took around 0.5-1 second to downshift and pick up speed. Is this because of clutch slip or is it a normal trait for dct?

[tmuzammil05]

How to get that rectified ?

[dayrider]

Take it to a decent electrician, ask him to check the heaters

@tmuzammil05 is it on cold start or its happening after every shut down & restart?
please visit an electrician to sort that out.

@a.m.photog what is maintenance history? when was last time transmission fluid changed ?

@pwuser15609321293 change your fuel station.

( corrected )

[nwzixh147]

Why bro?ive seen many vehicles knocking due to bad petrol quality as metioned by bro he is using attock total f6 is an excelent pump

[tmuzammil05]

It happens when the engine becomes cold , like after 3 hours after the engine has been turned off and then I have to connect one side of wire to battery terminal and other to the nuts of heater.
But once the engine is warmed enough, it doesn’t happen.
Also I got my transmission fluid and all fluids checked during last oil change i.e some 1000 kms before and the mechanic said that no need to change any other fluid.

[a.m.photog]

Don't know. Wasn't my car. I just borrowed it for a test drive.

AoA
I bought a Honda City 1.3 manual 2014
L13z1 engine
110k on the odo.
No histroy except Oil change.
These are the pics of Coolant taken from the radiator.
I know it seems odd just by looking at it but can anyone guide me to change it or keep it.
No heating issues.
Temperature is at 86c on OBD almost all the time and max it climbed up to 92c with/without AC in city and Highway driving.
There are no visible particles in the coolant.
Is it looking like Honda coolant?

[brownrose78]

@uzair3337
As you have no history proof, so i my opinion, it is better to flush radiator properly(Method prescribed here at Pakwheels by senior Pakwheelers; Dig it out) and fill with fresh new Coolant

[capsat]

@uzair3337 please read this thread it is plain DIY

[Xulfiqar]

This looks like someone mixed honda type 2 coolant with orange/red coolant.

Use a coarse tissue paper to see if oil separates from it

[uzair3337]

I checked on the tissue paper there was no residue or oil separation.
I even left it for some time after drying the tissue there was no oil left and no color or particles.
(I used a simple tissue paper as coarse tissue or filterpaper was not available and added few drops of coolant direct from the radiator when the car was parked for around 40hrs.waited for the film to form and the coolant to move on the tissue paper to look for oil seperation.)

[Xulfiqar]

Coarse tissue means heavy duty tissue paper (industrial cleanup paper), and if you dont have it then follow the below,

If you gently move the bottle to find out oil, you will see the oil “temporarily cling” to the walls as it falls back. Coolant has same viscosity as water and wont cling.
