Effect of upgrading oil cooler on CVT - installed with pics!

[Alpha_2nr]

Now that the mods have been done/cooler installed..........


........are there any quantifiable gains?

Numbers?

Performance?

Temperatures?

CVT Oil analysis to determine reduced/increased wear (based on metals content)?


NUMBERS....not opinions...or "I feel the car shifting better". Butt dynos are subject to influence by the power of the mind.

e.g. I've seen folks claim how much faster their car felt after they installed an intake and exhaust, only to dyno and see they lost hp

my car ran cooler

check teh pics

sport mode was enabled to run longer

if you using the fan, make sure it does not hamper the air flow

[bcozier]

i bumping this post....gonna try this very soon!!!

[X_Factor]

did mine over the weekend after soo long...
for a cheap mod its worth it.....noticable engine temperature drop during the day and more noticable during nights and with A/C on

One of my cars comes equipped with Xtronic CVT. Its one of the best out there on the market presently. If for any reason the temp exceeds its parameters it goes into fail safe mode & cutts acceleration until it cools down.

Therefore no need for external oil cooler. These external oil coolers IMO are really for long drives like on the interstate h/ways etc. i.e driving for long hrs between states / countries.

what you guys think about that product??

[xtech]

oil cooler makes a huge difference......i am currently still running an experiment with mine

VR4 TwinTurbo AWD auto with Tiptron mode using cheapest tranny fluid but using a "oil cooler" which used to be an AC condenser for a E24 maxi which is big.

Cools the oil way down then I pass it back through the radiator to warm it back up to operating temp.

This cheap oil still has the same colour an smells the same as when I first put it in must have driven it hard for 15,000KM so far

X_Factor , better to invest in one of the units that use replaceable screw on filters, that $12 will add up over time and be expensive, you would have to look good to get something taht you can use a filter easily and cheapy available here.

A filter will def be a good thing, some newer trannys, i have seen some mitsus, have a built in thread on filter.

whatever filter u use make sure and place it where the oil is hottest to get minimum resistance.

thats the next option but the hardest part is finding a location to bolt it securely

both links to same item

"accepts 3/4"-16 spin-on filters, for example, Fram PH8A and HP1"

I believe older SR's use that same kind of 3/4"-16 thread before they went M20

so easy and cheap to get are in our favour

take off your bumper and u bound to find a place.

only thing u need again for this kit is 2 x 1/2" npt to 5/16 barb fiitings, u could get at gas (cooking) supply places and bhagwansings plus other places.

The engine/tranny is GA15
since those did not come with a fluid filter, by adding one, can it cause any drops in pressure?

[krack korn]

yes, but pressure is not required in the return line, flow is important. Generally restriction on the fluid return is a bad thing but these screw on filters have bypass systems built in. Using the biggest filter you can fit will help with any restriction as well as what I said above about placing it at the fluids hottest point, so that is before the cooler(s).

plan to install one of these on a ck2 lancer

it already have one built in the rad so ill just plug the two holes with hose clips and a piece of hose

but is bigger nessary better? in terms of the transmission oil cooler?

or would the oil take too long to travel throught?

If bigger is better i have an idea

which may includes some cutting

[raybic]

dont have a cvt transmission have a invecII , since the install temp needle below half

[Ted_v2]

whoa.

where u got that cooler?
thing looking like what i need self

[raybic]

ordered it on ebay, really cheap and it comes with everything u need.

brand is flex a lite.

[xtech]

too small for my INVECS-II tranny but will be a good upgrade from stock in our climate for those low powered INVECS-II and INVECS-III CVTs.

[raybic]

stach whats the difference with ur invecs II compared to mines? its the same right? i heard if u put a big trans cooler the oil wont flow properly the temp will drop but the flow rate will be low.

my trans cooler away from the radiator and i break off my fog light bracket so that air passes through it . thinking about hooking up a fan.

[xtech]

My INVECS-II is connected to a motor with twice your horse power in a car twice as heavy as yours.

Plus it's AWD.

I get a very good cooling effect but no low oil pressure warnings or readings. Not saying you should go as big as me... cause you can't even if u wanted to just saying I did an it works well. What you got there will work well on my car in a cooler climate. But will better suit you in our hot climate.

Oil cooler is similar to what you got there but is 4 times bigger an can only fit in front my radiator where its conviently cooled by the dual radiator fans when the car is not moving.

heat is worse enemy of any INVECS an we have lots of hot days here most of the times stuck in traffic.

[Ted_v2]

So umm does bigger oil cooler = better?

i planning to get one 4x18 and install it but i heard it might be too big and actually cause more harm than good. Is this true?

[woopishk]

cvts normal operating premature is somewhere between 80c to 120c since heat is the enemy of cvt, an after market oil cooler is recommended for vehicles that put stress on the cvt for extended periods of time e.g. Taxis, Hilly terrain, or driving in hot temperatures... like trini weather....
what you need
closed loop water cooled system
1. an adapter
2. an inline thermostat rated at the right temp
3. a cooler with a fan
4. size of hose (must not be smaller than original pipes any restrictions will damage your pump)
5 no air in lines ( you must bleed system or you will lock up your pump)
if all these are observed you are good to go
4&5 are most important
