Radiators - stock vs aluminum after market

[Pakdamek]

Hi....as the topic, is it suitable to change to an aluminum radiator for a street daily driven car?

Thanks.

 

[DanzEterna]

yes. wat car u using?

 

[Pakdamek]

neo cps only....

no worries, i use 2 row aluminium rad on my daily kelisa, it really help cooling down engine especially when stuck in long slow traffic

aluminium radiator dissipates heat by itself better than oem copper rad, so in traffic jam where airflow is not high, aluminium rad cools ur engine better. on cruising where airflow is high, copper is better though since its more superior in transferring heat through medium

it sure helps if u like to keep high rpm at lower gears and ur not moving fast. also help if u had ur block rebored for much bigger piston, also helps if u raise engine compression etc..

basically its not like exhaust and intake where bigger can be disaster. in cooling case, the bigger the better, if budget permits :D

Uh.. that's not entirely true.

Copper radiators dissipate heat better than aluminium radiators, but the main problem with copper is the welded joints and that's usually where the contaminants come from.

However Aluminium is way lighter and because of the way it's joined (not welded) it can be made thinner and wider so in most cases Alu radiators have more surface area than copper radiators so its efficiency is there.

Both are prone to corrosion so use your coolants wisely and try not to expose it to corrosive stuff like sea water, brake oil, etc.

Both types of radiators have their pros and cons. But having a high compression engine and a lot of other things done to my engine my stock copper radiator is still serving me well. Auto radiators are wider and bigger compared to manuals. Just get a higher speed radiator fan to help further cool it down.

why bother to change when the rad still serve u better?unless if ur rad edi got problem ,instead of changing to oem, maybe can top up a bit for better rad...unless if your car runnnig high hp and you dunno where to spend your money, then go for it hehe..look more cool maa later ur engine bay...even my little 2.6 with high hp and race in sepang track using oem that manufactured in 1989 still got no problem...

thanks for enlighten me, so in my case, real life situation would a 2 row aluminium rad outperforms 1 row copper rad in cooling?

Yes, maybe...but not significantly . .

Most likely. But personally I'd say your benefits is a lighter radiator. And lightening the front end does wonders for handling! Throw in a CF hood and it'll be goooooooood

If 1 row stuck yr engine confirm overheat but if 2 row stuck 1 row and still have another 1.

its true, when i had my battery moved to trunk i felt more responsive front end, took me awhile to get used to it at high cornering speed

cf hood might be a bit splurging but nice to have haha

hehe wonder how u all can measure or felt front lighten when change rad n batery relecoted when driving....if cf hood or fiber hood surely can feel right...unless if you all race in track,drag or drift hmm sure need al these...am I right?please advise as im a newbie in motorsport industy

 

[upontheriversky]

hehe depends on people..i take note steering amount especially on my daily route so i can feel confidence driving faster everyday coz ill drive in same pattern

the kelisa has lightweight body, with stiffened chassis and suspension, steering becomes even more sensitive, so small change like that is easily noticeable hehe

heavier car can feel less difference i suppose, fun to drive fast coz u cant feel hehe

I wish I have cf balls like you all so that I can drive as fast as you all...but I have no car la...im just lorry/van driver...hmm

 

[mona-vie]

for your case, its not needed at all. A bigger 2 row aluminum radiator cools better than a single row copper. However, this is provided your car needs additional cooling.

The stock radiator for the Satria is more than adequate even if you TC your car.

Btw, changing radiator alone will not improve cooling because its controlled by the thermostat.

 

[tks84]

I am using 2 layer copper...so far good at the moment...temp also better than stock...can service...if aluminium cannot service..

i would like to see skyline 'transform' into Van jk~

haha....kan dah jadi skyline van aku...dah masuk engine skyline tu hehe..

i always wonder oem radiator was made to sustain much higher heat than stock or just enough only?

technically, 2 row should keep temp more stable around themostat temp since any heat induced is expelled faster right?
