coolant level???

[boydapa]

hello,

ako ko lng kng yun coolant level dun sa back up tank ba yun(yun puti na small tank) sa gilid ng makina nauubos ba yun??/


ksi after 3 months of usinh the car from my lasr measurement eh bumaba yun level nya.

ano ba yun rate of drain nyan kng meron man.

kumokonti ba tlga yun or dapat same level nun for a long time say 1 year o dinadagdagan talaga??

thnx

For 5 years I've been using my civic (87K km odo) honestly I can't recall an incident that I replenish both the coolant reservoir and radiator with water/coolant. Bilid nga ako dito sa civic ko pero I'm planning to flush the radiator and replace the coolant on my next PMS.

Pero on Pajero, I used to top the evaporator with Water/Coolant an average of 12ounces every 3 months.

nababawasan talaga yun due to evaporation.

[baiskee]

normal lang yan...like what HG said... nababawasan due to evaporation.

magtaka ka na lang kung sobrang bilis magabawas...like puno sya today then after a couple of days nasa kalahati na agad. pa check mo na lang agad kung may mga leaks.

3 months na ksi since last ko sya punuin to "Hi" eh ngayon malapit na sya sa "low". ang concern ko lng ksi is this normal?

hindi kaya lumalabas sa tambutso ko yun? ksi minsan may tubig eh?

ano ba ang mararamdaman o makikita mo pag humahalo yun tubig sa exhaust?
meaning kasama sya sa combustion process. just incase na nakapasok sya sa makina during combustion.

is that a possiblilty?

thnx

white smoke from exhaust + constant coolant low could mean headgasket failure..check mo muna..

normal lang yan, basta hindi lang sobrang bilis magbawas. just refill it to the high mark with distilled water.

Pag nagkukulang ang pressure sa loob ng radiator, dito sumisipsip ng tubig papasok ng radiator para mabot yung tamang pressure at gumana ng sapat ang water pump. Minsan nababawasan ito at tatatgas palabas ng reservoir pag over pressured ang radiator or lalo na pag barado ang cooling innards ng engine. Mas lalo na kung sira ang water pump. Babalik lahat ng tubig palabas imbes na ipasok sa makina.

True as it may seem, water level will eventually drop due to engine heat that could cause some part of it to evaporate.

unless the engine gets super hot, di dapat nagbabawas yan. the whole system is pressurized so you shouldn't lose any water... if ever konte lang talaga, then no need to worry tho. just top up and drive the car.

yung tubig sa tambutso eh dapat tuwing morning lang yun dahil ata sa moisture (forgot the real explanation hehe)... mag mainit na yung engine, dapat wala na..

[theveed]

kung magbawas man talagang konting-konti lang... I remember yung corolla ko dati I top off the reservoir (not the rad) siguro once every 6 to 8 months lang, and mga 100ml at the most ang nababawasan na coolant. Yung 1/2 liter na bottle nabili ko lasted me more than 3 years...

[nicolodeon]

Normal na nababawasan yan. Gaya nga ng sabi ni Bossing Ungas, sinisipsipn ng radiator yan pag kulang sa pressure. Nababawasan din dahil sa evaporation. Kung malakas ang pag-bawas, either may butas/tagas somewhere or may problema sa engine cooling system mo.

Kung tingnan mo dun sa "catch tank", meron dalawang level HOT and COLD--usually. Otherwise there's just a MAX and MIN level mark.

When the coolant reaches proper engine operating temperature, it will expand to the catch tank, raising the coolant level there. When the engine cools back down, it will resume its normal density and draw back the expelled coolant from the catch tank. This cycle repeats everytime the engine gets hot and cold again.

Like some posters already said, the coolant will evaporate over time, and the total amount of liquid in the cooling system and the catch tank will eventually subside. But this does not normally happen overnight, but should take months before you will notice the level going low.
