Radiator

[manjit]

I heard once recurrence failure of radiator was due to the radiator build up which is aluminium or wat ever the stuff is. One of my w/shop sifu even offered to change to brass or the copper type(can't remember which one), which according to him last better and longer than the current radiators with both of them kept in running good condition. Coolant prompt to reduce a bit of our radiator life span as it acts as the de-freezer. And yea, according to him this (copper or brass) radiator can last twice than our stock radiator.

price comparison?? -veli solly to ask but it's da chinaman in me to do so!

for the same core size, copper (not brass) cools better than aluminum. copper is also cheaper but weighs nearly twice as much as alu.

for the same weight of material, alu is a more efficient cooler than copper.

last i heard,this place in ss19 subang charges rm700 or rm800 for a copper radiator for my e30...but its thicker though so i'm still contemplating as to get it or not...

get the aluminium ones(BEHR avoid Nissen for E30 only) and use BMW coolant for God sake..its cheap..

I have been given to understand that it's easier to access copper soldering than aluminium welding. Izzat true-ah?
Any body kno how much heavier Cu is to Al by %?

Using other coolants will create flakes inside the radiator in the long run and end up clogging the radiator tubes. And also other coolants are not lubricating enough the coolant passages and other cooling related parts such as water pump, rubber seals etc. Stick to the original BMW coolants and flush every 2yrs as per recommended in the owners manual.

i just had my rad repaired.had the center core replaced for rm395 all in.aluminium core.shop is in jalan klang lama,very near heritage.

 

[Redd]

also heard that certain engine blocks must use certain kinds of rads. something about ionic reactions and whatnot. so if ur car comes std with a copper/alu rad, stick with the same material.

[manjit]

Ionic reaction can be reduced by using de-mineralized water. In your cooling system the water acts as the medium in between and the tendency of any failure are mainly due to the water itself. the conductivity of the water will determine the rate of the corrosion happening inside your system. Best way...maintain your water clean and clear...DIY flushing....jimat duit...hati pun senang...

back to topic.....lifespan of copper is still twice as the alu...minus the weight of course.....anybody around using copper type radiator...mai kongsi2

 

[GREEN KILLER]

any special procedures to flush a BMW radiator (DIY)?
