oke sudah jelas, pake radiator coolant lebih bagus daripada pake air murni (buangan AC). Sekarang pertanyaannya : utk Indonesiya yg fanas ini enggak diperlukan anti freeze agent, jadi merk2 radiator coolant apa aja yg recommended ?

pake yg merek2 branded terkenal aja...

beli yg concentrate seliter, trus sisanya tinggal di tambah in air suling atau air aki botol biru..

oke, utk airnya bisa pake demineralized water merk "Demiator" (30.000/gallon), tinggal nyari concentrate yg gak mengandung phosphate, merk apa ya ....

Demiator saya biasa beli di dua tempat deket rumah di Cirendeu (per gallon isi 3.98 liter) :
- bengkel EBA (Engine Block Autoworks, specialist Peugeot) di Jl. Pertanian, Lebak Bulus
- bengkel Radiator Rapih Sudiono (ada di Fatmawati, di Cinere dan di Cirendeu Raya ujung landasan Pondok Cabe)

pake yg tanpa campuran aja udah bagus...semua mobil saya pake prestone kuning 1 galon..
saya punya pengalaman pake merk bmw 1,5 liter trus dicampur air ac n air aqua isi ulang lama2 timbul ky kotoran ky batu kerikil tp dipencet hancur setelah dipompa n berulang2 ampe bersih gak keluar lg...
wktu itu overhead dijalan ternyata di cek bengkel semua bagus n ternyata tes dipompa radiator keluar kotoran bnyk yg bikin mampet...
mknya gak mau yg dicampur air biasa lg...mana mahal jg yg 1,5 liter..

Kalau yang harus campur sendiri, potensi-nya ya kepresisisan campuran mungkin ngga sebaik yang ready-mix, dan juga kualitas air campurannya itu sendiri

Idealnya, kalau campur sendiri, mustinya yang dipakai air murni (aqua destilata) atau air aki botol biru/hijau

Kalau dikasih air "biasa" apalagi air "mineral", malah ditakutkan bisa menimbulkan kerak/kotoran

ya kalo ganti di bengkel kita dikasih campurannya seperti itu...khan yg di jual adanya 1,5 liter...
mknya skrg saya bawa prestone galon minta ganti mekanik bengkel..kalo emang skalian servis....

ada 2 faktor om..

pertama, mobil ane (lipina) tuh anehh, kalo ane cemplungin coolant dgn concentrate 50 %, mesin gampang glitik.. ga tau knapa, biasa agak mendingan stelah ane bkin concentrate jadi cuman 20-30 % doank... yg ane perhatikan jg pas pagi2, lampu indikator biru lebi cepet mati... so far sehh uda setaon lebih ane kaya gini, radiator nya aman2 aja... pas dikuras jg ga ada serpihan karat..

yg kedua, harga nya jauh lebi murah... prestone segalon dgn concentrate cuman 30 % dan isi cuman 3.78 liter aja uda diatas 60an rebu... sdgkan concentrate gt seliter cuman 30-40an rebu... campur air aki botol biru 3-4 botol pun DC total dgn concentrate nya cuman 50 rebu paling mahal.. dapet nya bsa 4 liter lebih malah..

setau saya bukannya berapapun konsentrat tetap aja suhunya akan tercapai seperti termostatnya?
jd sitilahnya gak bikin ngelitik...tp gak tau dah klo mesin livina n yg lainnya..
kalo saya malah pilih yg bnyk konsentratnya...biar lebih tahan lama gak cepat berkurang..panas bgt mesin mobil eropa...

Repotnya kalau copot thermostat, jadi susah mencapai suhu kerja...

Omong2 soal konsentrat, tentu ada alasannya kenapa produsen membatasi sekian persen, sisanya musti air

Ada rekan SM yang kasih pendapat,

kalau pake coolant konsentrat (yg harus dicampur air/aqua distillate), trus ngisinya kelebihan/over dosis, efek negatifnya (selain bayar lebih) apa ya?

misalnya prestone konsentrat, di petunjuknya tertulis min 30% maks 70% (sisanya dicampur air), nah kalau ngasih konsentratnya kelebihan, >70%, kira2 apa berpotensi merusak cooling system?


:thanks:
Kalo ga salah, coolant (additivenya) ntuh efektif untuk fungsi pelumas dan rust inhibitor, naikkan boiling point, turunin titik beku. Sedangkan untuk perpindahan kalornya masih lebih bagus Air.
Jadi kalo kelebihan konsentratnya dikuatirkan justru mengganggu di proses pendinginan mesinnya.

ouw...gitu yah...
saya kira lebih banyak konsentratnya bisa bikin leih optimal :mky_01:

perihal lebi cool atau tidak, ane jg kaga tau om... scara lipina kaga ada gauge yg analog... ini cuman percobaan nubie ane yg ternyata hasil nya malah gt di livina ane...

@ kmpresorz : beda om, di botol prestone di tulis koq titik didih coolant concentrate 30 dan 50 %

ane lupa sumbernya..... tapi air biasa itu lebih baik untuk penyerapan panasnya dibanding coolant.
cuman di air biasa ga ada fungsi pelumas dan fungsi penghambat karatnya...makanya ditambahkan coolant,
cuman campuran coolantnya max 50:50.... kalau kebanyakan justru ga bagus buat proses pendinginan (heat transfer dari mesin ke radiator)

ini pas ngeblog http://otodiy.blogspot.com/2010/08/syst ... -cara.html
ada yang aku kutip dari workshop manualnya aerio :

Coolant
The coolant recovery system is standard. The coolant in the radiator expands with heat, and the overflow is collected in the reservoir.
When the system cools down, the coolant is drawn back into the radiator.

The cooling system has been filled at the factory with a quality coolant that is a 50/50 mixture of water and ethylene glycol antifreeze (70/30; in a market where no freezing temperature is anticipated).

This 50/50 mixture coolant solution provides freezing protection to –36°C (–33°F).
Maintain cooling system freeze protection at –36°C (–33°F) to ensure protection against corrosion and loss of coolant from boiling. This should be done even if freezing temperatures are not expected.
Add ethylene glycol base coolant when coolant has to be added because of coolant loss or to provide added protection against freezing at temperature lower than –36°C (–33°F).

NOTE:

Alcohol or methanol base coolant or plain water alone should not be used in cooling system at anytime as damage to cooling system could occur.
Even in a market where no freezing temperature is anticipated, mixture of 70% water and 30% ethylene glycol antifreeze (Antifreeze/Anticorrosion coolant) should be used for the purpose of corrosion protection and lubrication.

bukan coolant:air yang 50:50

perbandingan ethylene glycol:air cukup 50:50

kalau radiator coolant ready to use ya jangan ditambah air.

kalau concentrate harus ditambah air, baca petunjuknya di kemasan.

ya maksudnya radiator coolant ready to use kan punya perbandingan eg : air = 50:50
kalau beli consentrate dan dicampur akir kan bisa dibikin 30 : 70, dengan demikian proses perpindahan kalor nya lebih baik dibanding yang 50:50

kalo mnurut penjelasan om singachu... berarti ane ngerti dahh skrg knapa livina ane lebi ga rewel kalo dipakein coolant yg less concentrate...

kapan2 ane coba encerin lagi dehh jadi 20 %.... siapa tau lebi mendingan...

utk air sehh, agar ga menimbulkan kerak, biasa ane pake air suling atau air aki yg botol biru...

tapi jangan salah. untuk mobil lama dengan kondisi radiator yang sudah tidak lagi sempurna, coolant malah seringkali menghambat kisi2 radiatornya shingga radiator mampat..

Disarankan paling bagus 50% ethylene glycol.
Mungkin saja sekarang sudah ada super konsentrat, sehingga 400cc + 4 liter air, yang untuk orang awam angkanya terlihat seperti 1:10. Jadi lebih baik baca petunjuk kemasannya aja.
Air mendidih juga tergantung dari tekanan diatasnya, kalau panci dibuka, maka 100C akan mendidih. Tapi kalau panci ditutup rapat, air tidak akan mendidih, tapi pancinya juga bisa meledak.

http://www.wynns.co.nz/show-wynns-news.php?id=22

Antifreeze/coolant also protects against boiling, with a 50:50 mixture raising the boiling point of water from 248˚F (120˚C) at 14 psi, to 263˚F (128˚C). This 15˚F of extra protection will generally prevent boiling after shutdown in normal operation. Most manufacturers recommend a 50:50 mixture, not only for the freezing and boiling protection offered, but because this concentration also provides the needed corrosion protection.
