not necessarily kung walang thermostat dapat di mag ooverheat. some thermostats are compound or two valve thermostats and when you remove it, the coolant just recirculates in the engine block and not reach the radiator. this route for the coolant passage is provided for for faster warm ups. please, do not remove the thermostat, unless it is broken, then replace it.

so ano dapat ko gagawin sir? ipapagawa ko ito bukas, ireplace ko yung thermostat, ipacheck ko ulit yung assembly ng head, ipa overhaul ko ang radiator, ano pa sir? back-job ito eh, ginamit ko ngayon, mga 1hr of driving lumagpas sa center yung temp ko w/ a/c on..

Replace thermostat, check the radiator if mahina circulation ng tubig and kung may oil or bubles (if meron, cylinder head gasket yan malamang). No need to immediately overhaul the radiator kasi baka hindi naman yun ang problem. But a competent mechanic will easily see the problem with a thorough check-up kasi.

kung mahina ciculation ng tubig ano gagawin sir? wala po oil n bubbles sir, and ndi po bumabawas yung tubig sa radiator ko.. wala rin leaks..

- barado kapag ganun. Ipa-back-job mo na lang for sure.

could be barado radiator. yung dati ko kotse, pinatangal ko din thermostat pero overheat pa rin. pina-overhaul ko radiator ayon ayaw naman tumaas ang temp kaya pinabalik ko thermostat.

masama ba ang ayaw uminit sir? hehe

uu sir, so kelangan overhaul yung rad? bat kaya naging barado eh dati ok naman ito.. thanks sa mga ngreply!

dapat nasa operating temp ang makina for optimum performance which almost halfway. yung kotse ko dati noong walang thermostat ay less than 1/4 lang yung temp.

Kung ang engine temps ay hindi within operating temp, say 76.5 C - 93 C, either higher or lower than that usual range, mataas ang rate of wear ng cylinder-piston rings ng engine.

for example, overcooling ang situation. ang nangyayari ay nagcocondense ang vapors produced during combustion...hindi rin maevaporate ang trapped moisture sa lubrication circuit at mas mausok (as per my experience)...moisture trapped within the cylinder will accelerate wear because water have no lubricating property.

overheating is likewise bad also (seized engine)..ang pinagkaiba nga lang e yung overcooling tumatakbo pa rin ang engine.

sa case nyo sir e mukhang thermostat lang ang problema...stay away from the "old wive's tale of the thermostat".....or could be alam na ng mga ibang mekaniko ang epekto ng walang thermostat kaya lang tinatanggal nila para madaling masira...kapag nasira, may gagawin sila.kapag may gagawin sila, may pera.bow!....

plus the fact na ang thermostat ay considered as a wear item, it should also be replaced...lahat naman ng parts ng makina ay wear items eh.
