Alam ko gasgas natong tanong na to.Overheating problems

[Lerual]

Fellow Tsikoteers,
May Civic ako 2000 model.Here's the problem 5 months ago tumataas ang temp ng car so i had it check sabi Radiator needs to be overhaul,so i had it overhauled so after a week bumalik sa dating sakit,when the other mechanic pina check ko Thermostat daw sira na so i had it replace OEM.Sira nga naman medyo napa bilib ako.ngayon naman tumataas na naman ang Temp ng car. i dont see any leaks whatsoever sa mga radiators,hoses,waterpump etc.eto pa ang weird bat pag gabi lang tumataas when i think di na gaano mainit non.so i turn of the air con medyo bababa pero babalik din sa dating mataas na temp.Guys What do you think is Wrong.Sa umaga okay naman pag gabi lang.Pls HELP!
THANKS SA LAHAT,Godbless

Try pa check ang Aux fan baka mahina na ang ikot, maluwag ang conenction kaya iontermittent ang operation.

[Lerual]

Thanks That sounds good..Kasi yung tinanungan kong mechanic.sabi nya check nya raw ang fan ko baka mahina na nga raw ewan ko sa pagi kot o ano...basta sabi nya sa fan muna raw..Thanks..

[wildthing]

nagaagawan ng koryente pag gabi - sindi ang ilaw kasi...so the fan is not getting enough juice...unlike sa umaga na solo ng fan ang current. tapos the a/c fan aids it pag naka-on ito sa gabi....

question is 2 ba ang fan niyan - one for a/c and another one the normal fan?

[Lerual]

Wildthing,
Yes one sa aircon,one sa radiator fan..
Thanks for sharing all your views...

[hyperthread]

Aux fan po yan since nagooverheat sya pag nakabukas aircon. Sira na po yung carbon brush ng aux fan mo po or baka loose connection lang.

[washburn]

sa umaga ok ang aircon hindi nagoverheat at sa gabi lang nagoverheat?
try mo rin pa check temp sending unit at temp sensor gasgas narin tong sagot ko hehe share ko lang medyo parehas tayo ng symptoms e pero pacheck mo muna yung fans
mas affordable kasi yun e hehe

[Lerual]

Fan na lang nga sana.pa check kuna ang both Radiator at Aircon Fan.Thanks To all..later say ko ang results..
Thanks

check your radiator cap na din bro. baka nagbo boil ang water sa reservoir tank, kaya nag uubos ng tubig, kahit wala namang external leaks.

[speedyfix]

had the same problem before. replace all the ground wires of the car and clean off the surfaces na pinaglalagyan. mali lang signal pinapadala nyan sa gauge mo.

Guys,
Mukha ngang walang marunong sa pampanga naglibot ako last saturday and sunday nagugulat pa ang iba bat daw pag gabi lang..meron pa sa signage nya expert from banawe pero di rin alam.Di alam ang sakit ng kotse.nawawalan tuluy ako ng gana...Dami nating suggestions pero ill take them one at a time..Thanks Guys..

Simple lang naman malaman kung mahina ang ikot ng fan. You can even do it yourself. Just pop the hood and engage the aircon. Pag mabagal ang takbo ng fan, yun na yun. Pero since the mechanics you've been to has seen your car, hindi siguro fan ang problema. They would have diagnosed the problem easily.

Baka naman yung temperature sending unit or yung mismong gauge ang may tama? That is, kung wala naman leaks sa cooling system or kakakibang usok mula sa muffler.

[Lerual]

na try kuna yun makita ang mga fans umikot parehas naman mabilis umikot.di rin nauubos ang reserve water,di rin kumukulo,no white smoke,di sira ang radiator cap palitan kuna rin for assurance. Si speedyfix try ko yung sinabi nya.change the ground wires and clean,tapos pa check ko ang gauge

Mga sir/mam, pa advise na din kasi exact na nangyayari (rise in temperature almost sa red line na and pag stop ko to check kumukulo nga water sa reservoir) sa ride ko ngaun ito pag tumatakbo ng 90-120kph for about 10mins or more.

Nae-experience ko lang ito pag nag byahe kami sa SLEX or NLEX. Pero pag city driving nman at nagbu-burst speed (100-120) ako like sa edsa or C5, totally walang problema nman related to overheating.

What could be the problem or culprit that causes the problem??

Start first by having your radiator flushed and cleaned then checking your aux fan operation and thermostat; a stuck thermostat could mean water/coolant flow isn't sufficient when you're running at higher rpms.

Thank you for the advise vinj. When you say have it cleaned, does it mean i got to have it "overhauled"?

[miked]

a thermostat that fails to open ("stuck in the closed position") will overheat the engine no matter what the engine speed is....

a missing thermostat (i.e. removed) will overheat the engine on low speed runs (traffic) and overcool on open highway runs....

symptom is overheating at open highway and prolonged high engine speeds......

if all of the items stated by sir vinj checks out okay, check your belt, belt tension, water pump, and then your hoses especially the lower one.....usually, the upper hose is the first to go. check them both anyway.

experienced the same problem and it turned out that the lower hose is collapsing at high engine speeds because it (hose) was soft.

water pump creates partial vacuum at the suction side (lower hose).

Hello po. Up ko lang po tong question na ito, needs some enlightenment cause Im also experiencing minor overheating lately. Thank you po sa mga magrereply to educate us about the differences of radiator flush and cleaning versus overhaul.
