Engine Coolant

I just had my radiator drained rin kina Chieffy recently. Unfortunately, naubusan na sila ng Caltex long-life coolant, so I had to run off to Cash & Carry. I was able to buy the Castrol Long-Life Coolant (color blue). Our mistake was not reading the label, so we diluted it 50/50. Upon closer inspection, 2:1 pala dapat ang ratio. Ok lang naman siguro. Ngayon, napansin ko, once nag-start ako, it takes a longer time to reach the normal 1/3 mark of my temp gauge.

2:1 and 50/50 mean the same thing. Naipaliwanag na ata ito somewhere in this thread or sa isa pang coolant thread.

1:1 is 50/50... 2:1 is 75/25 na diba?

The main reason why the "coolant nakakasira ng radiator" myth came along is because people almost NEVER drain and change their coolant as noted in their manuals back in the 80-90s... Coolants (regular ones) never last more than a year, after 6-8 months they start breaking down leaving deposits which clogs the radiator fins and such... If you change/drain your cooling system as directed, it should not be flakey

btw kasama ba sa PMS ang ganito? dependent talaga kasi ako sa casa sa maintenance ng sasakyan eh... just asking naman

sir OTEP and sir theveed

i think 1:1 = 50/50 din but 2:1 = 100/50 so for every 10L water, 5L coolant dapat.

correct me if im wrong

sa tingin ko lang naman po.

Medyo nalito rin ako dito. Pwedeng pa-clarify kung ano talaga?
By my understanding, 2:1 is actually 66.++/33.++. For ex, a 3 liter solution (combined) of coolant and water would actually require 2 liters of coolant and 1 liter of water (or vise versa; 2 li water and 1 li coolant) to fulfill the 2:1 ratio. Tama po nga ba ito?

sa toyota casa.. they change the coolant every 40T Km and 80T km .. not sure with other car brands..

on my dad's 2000 revo.. we always changed the coolant every year starting from the 3rd year of the car..

nadala na kasi kami sa previous car namin na nabubutas lagi radiator sa kahihintay ng 80Tkm/120TKm .. mura lang naman coolant compared sa repair ng radiator.. lalo na at mahigit 10 years bago kami magpalit ng car..

Pareho intindi ko as with pissword and bacon. 2:1 means 2 parts water, to 1 part coolant. So in a 3-liter mixture, 2 liters is water, 1 liter is coolant.

Bacon: Tama ka pare hehe 66/33 nga 3:1 na yung 75/25 hehe sorry.

ang gawa ko kasi 2 liter na distilled water at 1 liter na coolan para sa mga 3li na radiator initially makulay then in after a 4-5 months dun mo mapapansin na halos plain water nalang yung nakikita ko thats the time na mag padrain na ako ng tubig including preasure flush ng tubig at hangin sa radiator na rin ..dko na alam ang reading ng kung ilang kms na eh hehe..tama po bang process ito ng pag drain a radiator d pa naman kami nagpapalit ng radiator panay hose lang at clamps recomended kasi ng mechanic ni father dear
