Is this normal? Nagbabawas water sa coolant reservoir

[anthon05]

Hi mga fellow tsikot members.

Just want to ask kung normal ba magbawas ang coolant reservoir ng water around half glass or maybe 100 ml in

a month. My ride is isuzu crosswind just replaced with new radiator. My friend says dapat hindi nagbabawas ng ganung

karaming tubig in a month. What do you think? ano kaya problem checked hoses wala naman akong nakitang leak.


thank you

it is not normal for 100cc fluid loss in a month. if you have not found the leak, it maybe that your cooling system needed to be bled of air pockets just like bleeding the brake system. the other possibility is that your radiator cap might not hold pressure under load or the pressure gasket is not sealing liquid tight. the radiator cap leak usually does not leave a trace of spilled coolant since the air flow from the ram air or the radiator fan accelerates its evaporation. you can add a leak detection dye mixed with the antifreeze to show forensics the evidence of the leak

First question is: Gaano mo ba kadalas gamitin ang sasakyan mo?
Second: Gaano katagal?
Third: Usually gaano kalalayo?
Lastly: Usually mga ano oras?

This are the important questions should be considered..

I used it everyday. avg. of 20km or around 2hrs travel time. on weekdays when I go to work in the morning and go

home at night. on weekends iba iba oras. around 500 to 550 km a month.


hi Jick,

paano bleed cooling system? possible ba kulang lang sa coolant. I just put 1 lit Prestone concentrated coolant.

Worry ko kasi on Xmas vacation I might go out of town, you know ibang story pag long distance high rev and long
travel time baka biglang magkaroon ng major leak. I looked everywhere wala akong makitang leak maybe because

very minimal kaya hindi makita.

Thank you

to bleed: simply remove cap then start engine and let it warm-up up to operating temp. upon reaching operating temperature, you may race the engine several times. some people do it on a slightly sloping ground with the front of the car on a higher elevation.

Hindi normal nga kung nagbabawas ng ganun kadami, yun nga pwedeng possible cause kung walang mga leak, yung radiator cap

th

the bleeder screw is usually adjacent to or at the thermostat housing. some cars use the same brake bleeder screw for coolant bleeder. nissans use a short 5mm screw (10 mm head) and has a gold in color tag telling you it is the bleeder. on isuzu, look for the highest part where the antifreeze will pass through. if your radiator does not have a pressure cap but instead on the recovery bottle, it is a closed loop system and bleeds itself

[anthon05]

Ok Thank you. Bleed ko and then observe again.

[vinj]

Check also your radiator cap if its fitting properly with the new radiator.

[anthon05]

Yung radiator cap medyo mahigpit. I mean maybe because the radiator is new. I'll buy a new radiator cap so I'll

see kung ito nga.

thanks

any updates on this sir? for my case, i suspect a leak, nagbabawas daily (kaunti lang though).

[aloofkid]

Bump ko lang itong thread na ito.

The second day since my dad gave me his project car nag overheat ako, so naging habit ko na mag lagay nang tubig sa radiator and coolant reservoir before I use my car. (Matagal na stock yung auto)

Fast forward to this day, two weeks ko na napansin na hindi ako na nababawasan ng tubig sa radiator but laging ubos ang tubig ko sa coolant reservoir ko.

I texted my dad kung ano ang problem, he told me wala daw problema, kasi may may tubro daw yung tsikot, mainit daw yung turbo kaya laging nauubos yung tubig ko sa coolant reservoir.

Madala pag lumalabas ako ng tsikot naririnig kong kumukulo yung coolant reservoir ko, pero normal naman temp sa gauge ko.

Ano problema dito?

Thanks guys!

Palinis mo muna radiator at check mo mga hose at water pump bka my leak.. Isa din common ung radiator cap.. Kung di fan clutch ung engine mo bka malambot na ung clutch.. Pag ok lahat iyon tiyak my pressure na head cylinder ng engine mo

I've owned a CRV, City before and now I'm driving an Elantra and Grand Vitara. For the CRV, City & GV, never nabawasan yung ng coolant yung coolant reservoir. Pero yung Elantra ko, after a few months, nababawasan ng coolant. Same din with my dad's Starex. Ganon ba talaga mga Hyundai?

Another question: Do I need to go to a Suzuki specialist talyer to have my GV's airocon looked at? Napansin ko kasi wala nang lamig na lumalabas sa left vent (center part ng dashboard may dalawang left & right aircon vent) pero sa right, may lamig pa.

Di naman pressurized ang cooling system ng crosswind kaya di kailangang ibleed.
May leak yan di mo lang makita, kapag mahina lang ang leak sa init ng makina
natutuyo kaagad di mo makikita na may basa. hanapin mo na lang kung may recidue ng
coolant sa mga hoses pati sa likuran ng makina, kung meron doon yon may leak.
Kung may usok na maputi head gasket, kung nagkukulay brown ang langis dito humahalo ang coolant.

Are you sure?

Who told you that?

Mga truck nga namin sa probinsya puro pressurized ang cooling system.

Sir correct me if Im wrong, ang pressurized cooling system ay walang lagayan ng tubig ang radiator,
walang radiator cap, wala din na coolant reservoir. Sa expantion tank ito nilalagyan ng coolant o
tubig.

Yes there is a pressure when hot, but pressurized cooling system is different and its mostly found in
european cars.

Like what brand of european cars?

In todays cars, be it euro, japan, korean, etc. ........ the radiator cap (i.e on top of the radiator) is almost non existent. Coolant reservoir is one and the same as expansion tank, IIRC.

Or can you name a euro brand that has a separate coolant tank and expansion tank?

I have euro and jap cars. And I never put water straight into the radiator, its always straight into expansion/coolant tank.

Like BMW and almost all euro cars has no coolant reservoir tank separate from the system.
Expansion tank of these cars are part of entire cooling system or coolant circulation and the system is sealed,
that's why they called it pressurized.

Jap cars coolant reservoir serve only as a coolant storage when the excessive coolant and pressure from the radiator
release during hot and back to it when cold.

The two system are different. We can filled coolant in coolant reservoir just to put it into max. level but you can not
filled the system full via coolant reservoir, you have to use the radiator cap. In pressurized system no option only in
expansion tank to put coolant through the system, then bleed to assure that there is no air in the system if there is
it will create problem.

So, for example in a "cold" BMW engine, if I open the coolant reservoir cap, do I risk losing pressure in the cooling system?
