Do we really need a transmission oil cooler for new Honda city cvt gearbox ?
I bought a Hayden rapid-cool 676 size, and not yet install..
mind to share some experience for those already installed for their auto car.. and especially those who installed for their cvt gear box...

thanks~

new car is it?

ya~~~

erm....... new car + mods... better check with honda before you mess with it.....
messing with the headunit, adding reverse cameras, these accesories is one thing, messing with mechanical components, is a whole dif story

inb4 transmission warranty gone habis....

I already send my car outside service liao...
2years + liao.

How come honda not fit the transmission oil cooler at the first place if the cvt box really need it?

save cost maybe ? i'm not so sure...

Hmm, how about those ultra racing bar? stiff rings, double layer aluminum radiator ?

Better not, replace ctv fluid frequently would be better.

ah ok not really a new car...

then all is fine BUT remember this... added coolers mean that it takes additional time for the car to warm up.... remember running things cold causes lots more damage compared to running the car hot.... if this car is used long distance then might be worthwhile installing it, BUT if you use it for short runs, the cons will outweigh the pros.....

i speak with 'some' experience with engine coolers


- ultra racing bar, basically stiffens everything, but also adds extra harshness to the ride... *depends on which bars you reffer to ofc*
- stiff rings basically get the assembly straight, imo waste on a new car but ur money, your call (no real harm done here so its alright)
-double layer aluminum radiator, these help if the car runs hot, otherwise theres no point (if it operates in the optimum temp when you drive, whats the point?) *useful if u constantly do high speed pulls/runs ofc*

Ic, noted and thanks for the reply bro... you got your point too..

Most of the time i use my ride is for short distance, every time i start my car.. i make sure my water temp go up to 54 degree Celsius, Engine oil temp also make sure go up 50 degree above only start to press my gas pedal..

Since Malaysia weather is hot most of the time, city road jam here and there, lot traffic light..so our auto gear box change gear more often.. more heat produce and over normal working temp = reduce lifespan of our GB..

but one thing that troublesome me is the CVT.....very sensitive if compare to other auto gearbox...

I think i will put this cooler for my myvi icon 1.3 auto ...lol

haha dependslah kene monitor dulu, see if its always going warm..... but i do agree with the guy above, just replace fluids earlier, accordingly it helps?

Ya, i already replace my CVT fluid every 30k KM/1.5 years instead of 40k Km/ 2years (stated by HONDA Malaysia)

ahh then all is good, take care of your car, and it will serve you well

Does city equip with radiator integrated atf oil cooler ? Cannot be totally no transmission cooler right ?

Do you have dedicated temp gauge for oil and water temp?

the car has one of the temps shown... so he must have installed one at least since he so confidently gave out numbers

also mls_gameryou did mention that we do lots of getting stuck in jamms...... am not sure if that actually increases the gb temp... cause nothing is actually running... afaik, it usually goes up on the move.... especially when climbing hills and running at high speed.....

yes they basically run the CVT Cooler line to the engine radiator and back. Its there since the 2nd generation Honda city IDSI / vtec.
For all proton Cvts, they come factory fitted with external CVT cooler.

So doesnt mean honda dont want to fit doesnt mean it wont cool down. Probably the engineers felt the engine radiator is sufficient.

Don't screw with cvt, adding coolers change oil pressure , you don't know what will happen if there isn't enough pressure ,

simple rule if it ain't broken don't fix it

and please please use original Honda cvt oil , not even branded Japanese aftermarket , with makers offering long warranties they make damn sure their oils are over engineer, after market don't give a shit

As far as I know, the blue engine cold light will switch off at 54C. However, I don't think there is an engine oil temperature sensor equipped on City.

Yup, pivot throttle controller with water temp monitor and work engineering oil temp pro gauge II.

Ya, that the problem...so now i plan to put this on my auto 1.3 myvi ...
since out there lot of auto myvi already installed atf cooler for their ride...

when we stuck in jam.... we will change gear more often right ? temp also increase ? correct me if wrong...i'm newbie...

cvt, no gears. afaik heat for a cvt is generally generated during acceleration, slip and constant high speed

also about the oil pressure, actually an added oil cooler usually does not affect the oil pressure much, if its seup properly, its a minimal dif (infact no noticeable change in pressure in the case of my engine oil cooler)

I've fixed/added this cooler on all my auto ride, Vios, Altis, Civic.... not a problem over the years of ownership

Noted bro, thanks for sharing the info..

Ya, i bought this Hayden rapid cool is 676 size, suitable for small and sedan car..... the smallest among this series...so in term of pleasure maybe got drop.. but not much..

mind to share me the workshop u installed ?

Quicksave Subang

how is it now ?

2nd feb 2024 his last online bro.
Anyway honda cvt just take care of by changing the cvt oil on time and most importantly, dont accelerate fast aka lenjan the car.
Honda cvt has been know to be the weakest and most fragile. Some videos even show honda cvt steel belt which always breaks smallest in size aka fragile compared to other brands like mitsubishi lancer/inspira, audi, toyota, etc.

thanks bro, did't notice he was absent for a while. yup, you are right

Yup, actual reason is no taking care of lube and drive too agressively. Honda CVT belt got many videos shown with excessive vibration it can shattered into pieces, add CVT cooler also wont help if this is the case.
