radiator reservior throws water out

[bistro]

guy,
i have a 1997 Toyota Lite Ace

Dati, nauubos ang water ng radiator. so i just keep on putting water everytime i use it. pero recently, masyado mabilis mawalan ng water. at napansin ko na water is being spilled from the reservior when i stop the engine. water isn't thrown out when the engine is running.

3 days ago, i had my radiator changed. ngayon kulay black na yung radiator. pero water is still being spilled out from the reserviour everytime i stop the engine. so after 3 days, medyo tumataas na yung temp. kasi medyo madami na ang tinatapon na water.

ano kaya ang problem?

Hindi kaya malapit na mag-stuck up ang thermostat mo or mahina na ang pihit ng water pump mo?

[bistro]

sir,
wala na po yung thermostat ko. tinanggal na dati pa.

[Ungas]

Wala na palang thermostat yan, probable cause of water pump failure. May leak na ba sa ilalim nung pump?

[bistro]

sir,
wala naman po akong napapansin na leak. pero ganun po ba ang symptoms ng water pump failure - yung nagtatapon lang kapag patay ang makina?

I have the same problem before, I found out that AUX FAN is not working!

You can check AUX FAN !!!
1. Disconnect the wire from Engine Coolant Sensor ( located in thermostat housing).
2. Switch the key ON.
3. Now, look at the Fan if turning.

Hope this will help you!!

sir igobaby,
wala po akong AUX fan sa liteace.

[igorbaby]

bistro,

try to check Fan belts, maybe it's slipping or not on proper tension. Or, needs some Cooling system cleaning.

i will check that. kakainis talaga kapag hindi mo mahanap ang prob. hehehe. thank you sir igorbaby.

water pump malamang, baka corroded na yung shaft key kaya free-wheeling na yung impeller sa shaft, or even a worn impeller. replace na yan palagay ko.

bad practice yung tinatanggal ang thermostat, mekanikong palpak lang gumagawa nun. REMOVING THE THERMOSTAT EFFECTIVELY REDUCES THE COOLING CAPACITY OF THE COOLING SYSTEM BY 50% SINCE THE COOLANT FLOW IS DIVIDED INTO BY-PASS AND RADIATOR AT ALL TIMES, EVEN WHEN THE ENGINE ALREADY NEEDS 100% COOLING CAPACITY. kung gusto mo na sure meron water flow lagi, kuha ka ng old thermostat, heat the temperature sensing bulb so that the valve will open and then weld it permanently in the full open position. installing this in the engine will block the by-pass and flow 100% of the coolant to the radiator. you will however experience longer engine warm-up time since the thermostat is now permanently open.

[bistro]

thank you sir yebo.
i will look for a second hand thermostat. and have my pump checked.

nagtatapon pag nag stop ka lang? Pwede rin kasing may sira na gasket mo or the cylinder head itself. Pag nagka singaw dun or hindi na lapat cylinder head pressure will push the water out of your cooling system. Pag compression test mo rin yung engine.

[bistro]

garyq,
nagtatpon ng tubig when i turn the engine off. and not during stop and go traffic. kakapalit lang po ng cylinder head gasket mga 2mos ago when my liteace overheated. at "shaved" ng konti yung cylinder/piston heads ko.

[speedyfix]

who replaced it? baka mali torque nila kung nagbabawas ka parin until now.

[bistro]

speedyfix,
okay naman yung shop. kakilala namin.

i just went to banawe kanina to buy a thermostat. 500pesos. then when they removed the radiator cap assembly, meron pa palang thermostat dun. and there was a small rubber (parang galing sa tsinelas) na naka-stuck sa thermostat kaya hindi siya makasara nang maganda. so pinalitan na yung thermostat and mukha naman ok. =)

keep you updated.

sana this theread would help other liteace owners. =)

i just came home from the airport. medyo gumanda nga yung temp ng liteace. pero nung malapit na ako sa bahay, medyo tumataas pa rin yung temp. pero not as fast and not as high as before. wen i got home, nagtutulo na naman from the reservior.

i guess my next move is have the water pump checked diba?

[BlueBimmer]

maganda dyan change everything, waterpump, hoses etc. kung pwede nga pati radiator mismo. tapos problema mo and your cooling system will be trouble free for a long time.

3 days ago, i had my radiator changed. ngayon kulay black na yung radiator. pero water is still being spilled out from the reserviour everytime i stop the engine.

ano kaya ang problem?

1. Bago ba radiator na pinalit mo or second hand? Kasi as far I could remember eh walang effect kung ano mang kulay ang radiator mo. If that is second hand, have it overhauled.

2. Meron nabibiling engine flush na lilinis sa cooling system ng makina. Some service stations offer this lalo na kung katatapos lang ma overhaul ang radiator. This will remove all the rust and "bara" sa iyong cooling system. More or less, it works like liquid soza pero pang makina nga lang. Nirerecommend lang ito at certain intervals like just after a radiator overhaul dahil nakakatigas rin ng mga water hose ito pag napadalas.

3. Usually ang mga radiator shops recommend upgrading to a bigger radiator kung hindi makaya ng makina. Better look for the tanso and not the plastic coz mahirap maghanap ng nagooverhaul ng plastic na radiator.

[bistro]

brand new naman po yung radiator ko. baka mag-canvas ako ng water pump. is there anyway to know kung sira ang water pump? wala naman akong nakikitang tulo eh. at matigas naman ang ikot ng fan ko when i try to turn it.

i will try to have my radiator flushed din. thanks guys.

Why not try having your cooling system cleaned by a machine called lavramon? Instead of having every part flushed. It'll cost you less.
