civic 98: rising temperature on high speed

[rapido]

hi guys,

I'm a newbie here, also a newbie with cars. I got my 2nd hand honda civic 98 for more than a year now. Here is my problem:
- At high speed (120 - 140) tumaataas yung temperature ko, pero pag bibitawan ko gas para bumagal, bababa naman cya. Pinacheck ko cya sa talyer, sabi is try ko muna daw ipalinis yung radiator ko. So pinalinis ko cya (water pressure lang ginawa) and same parin problem. So What I did is pina overhaul ang radiator. Habang inaayos yung radiator, sabi ng gumagawa is dapat daw tanggaling ang thermostat kc ganun din ang problem nung client nya dati. Di naman "daw" need ang thermostat sa pinas, so as his advice pinatanggal ko na.

I tried to have a quick 120 - 140 speed run and mukhang di na nag occur yung problem (pero i still need to test it in a long drive run with high speed).

Heto po questions ko:
1. di po kaya thermostat lang yung problema nya, kaya nung tinanggal ang thermostat e mukhang ok na?
2. pano po ba malalaman na sira ang thermostat?
3. ok lang po ba na walang thermostat? Or I need to buy a new one at palagay ko?

Thanks po ng madami, hopefully matulungan nyo ko.

Had the same problem with my Accord. Had the radiator hose replaced. At higher revs, the hose constricts and cuts off coolant circulation. This also affected the thermostat which had to be replaced too.

Sir, better have a the thermostat re-installed or better yet install a new one and replace all coolant hoses. Also, I am not sure if the same applies to a civic engine, but for the Accord there were other coolant hoses to be replaced other than the upper and lower radiator hoses.

Its a 10-year old car, parts wear out.

rapido,
there had been posts about the disadvantages of removing the thermostat. please ask the moderator for a repost.

Maaring yong thermostat ang isa sa mga problema. Ten years wow!, long overdue na at dapat ng palitan ang thermostat ng kotse mo. Ibalik mo yong thermostat ng kotse (bago ah! hindi yong luma) dahil importanting parts ng cooling system yan ng iyong kotse.

Sa sinabi nilang hindi kailangan ang thermsotat diyan sa Pinas.... thats a BALONEY.

+1.

napansin niyo ba kung meron natangal na dumi sa radiator niyo nung pina overhaul niyo?

bilhan niyo ng bagong thermostat yan para maging normal ang working temperature ng engine niyo at hinde naka bypass.

EK din po itong sasakyan ko, stock na stock at walang naka bypass.

[rapido]

thanks po mga sir.

Madami po natanggal na dumi sa radiator ko nung pina-overhaul ko sya.

So bale need ko gawin are to buy a new thermostat (sa casa para sure na orig noh?), ipalagay ko sya para di naka by pass, then replace all radiator hose ( civic 98 vtec vti po ang car, dalawa po yun noh? isa sa taas at isa sa baba?). Balitaan ko po kayo. Thanks po ulit.

I think tama yung move mo. And while you are at it, the water pump (or radiator pump) to circulate the water pa check mo din. Worst case scenario need mo na palitan.

Kung tumataas ang thermostat mo it could still be working pero it's a good move to have it checked.

Good luck.

dagdag din ako,
kabibili ko lang ng thermostat sa piyeza las pinas perepereho lang naman daw ang gamit na thermostat ng civic, orig 1,200pesos replacement 800pesos, kaya alang ang raplacement walang oring kaya kung sira na ang nasa luma wala kang mabibiling oring lang, kaya ako binili ko orig na, ang replacement na rad fan 1,300pesos

Mga bossing, heto po updates, Sa Casa (Honda pamapanga) ko na dinala at heto findings:
1. Put thermostat
2. Radiator overhaul (may dumi parin daw kasi)
3. Ok pa daw radiator cap and hose
4. Computer test
5. Road test

With the above, nagbayad ako almost P2000. Same parin po ang problema with the new thermostat and radiator overhauled, tumaataas parin ang temp on high speed. Nagpupush parin ng tubig sa reservoir the eventually, nababawasan cya (below level pag malamig na makina). Kaya pinatanggal ko na muna ulit ang thermostat to prevent the rising temperature on high speed.

Need daw cya i top overhaul (gasket). P25000 daw po ang minimum estimate nila (sakit sa bulsa nito, iipon muna). May mga iaadvice po ba kayu? Thanks po.

pag ang tubig ng radiator ay palabas ibig sabihin kelangan ipamachine shop ang cylinder head mga 1.5k yun plus ang cylinder head gasket.top overhaul na talaga yan.mabigat nga talaga ang magpagawa niyan.pero kung wala prob ang wala termostat ok na muna yan pero wag ka makasiguro na bigla kang itirik dahil nag overheat na.check mo parati ang temperature mo.ingat

[baludoy]

medyo similar din ang prob ko kasi every almost week i have to refill my reservoir. seems to be no leak if checked visually, thermostat & temp sending unit (?) are about a year or two old only, & i just had my rad overhauled last october, & my rad cap is now rated at 1.1 (it still looks ok pa din naman also). what more & where should i check?

btw, the car isn't overheating naman but i sure want to stop the constant refilling of the reservoir because it means there is something wrong w/ the cooling system of my vti

[rapido]

Thanks po sa advice mga bossing. Iipon muna ako. I try ko rin canvas sa ibang shops kung magkano top overhaul nila. May mga maiiadvice po pa kayu good shop? If conti lang po diferrence, baka sa casa ko pagawa (para mas sure?) Sa casa po ba is may warrantee repairs nila like this?

brad baludoy, baka po may butas na maliliit ang mga hose ng radiator. may nabasa ako dati na some butas can't been seen by the eye.

[roberto_minosa]

Yeah, that might be the problem. My bud's SiR overheated once when he did 200km/h. A lot of car nuts said that the cylinder head was warped, and made radiator problems worse due to leaks.

[hntk_03272000]

share ko lang po...naalala ko agad ang forum na to,kahapon paakyat kami tagaytay convoy ko civic vitec nag overheat sabi ng driver lagi daw nag ooverheat ang civic kasi pag mainit ang makina lumalabas sa radiator ang tubig tapos garalgal na makina palagi na daw yun sabi ng driver ang ginagawa niya pinapalamig lang tapos ok na daw uli.sabi ko top overhaul yan.matagal na daw gusto pa top overhaual wala lang budget boss niya kasi 20+ daw sa honda shaw labor materyales na daw yun

[isa1023]

seems to me na sakit ng vti talaga ang cooling system.
I had the same problem with my esi pero ngayon ok na.
resolutions were a new rad cap (1.1), radiator overhaul and a new thermostat. yun ayos na..

napaisip lang ako, diba mas malaki ang radiator grill ng ek (vti) kesa eg (esi/hatch) pero bakit parang mas marami akong naririnig na cooling problems sa vti? or am i just being noob? (pardon)

I have the same problem with Civic 97. The temperature rises pag over 100kph or kung uphill climb. Sometimes sa NLEX tataas yung temp so I'll switch off the AC para bumaba ng konti. Pero pag dating sa toll booth, bababa na sa normal even before I get to pay the toll fee...saglit lang normal na ulit temp.

There would be days that I wouldn't even experience a temp increase basta steady lang takbo at 100kph. Normal city driving in Metro Manila is ok din except on hot days na hirap din yung AC...tumataas na yung temp.

I've been told na radiator overhaul daw kailangan. I also don't have the thermostat anymore. Pero hinde naman nababawasan ng coolant/water.

Why would a top overhaul be required? What is causing the overheating at high speeds or uphill climb?

[raine]

check mo ang rad fan baka mahina na

[rapido]

hi bynnos,
Nagtatapon na kasi yung yung radiator sa raditaor resevior nya. Sabi din sa casa in may tama na daw yung top kaya need i top overhaul.

Updates lang po ulit, kanina lang habang drive ako:
1. going to airpor, NLEX drive from Pampanga - tumaataas temp ko sa NLEX (no thermostat), need to stop sa Shell GMA kamuning. Stop aircon, tapon yung hot water sa reservoir(above gauge kaya alam ko na tinatapon ng radiator ko dito), put fresh water sa reseivor (on normal gauge) put fresh water sa radiator.
2. Airport pabalik ng Pamp (NLEX) - off aircon, hinh temp occurs on high speed (110 -120)

Bale, same issue occur pag wala o pag meron thermostat. Gumagana naman po ang fan, nag aautomatic cya (di cya nakarekta).

[fcuyugan_29]

same problem with me my fan working automatic triggered by sensor,it means my thermostat is working.d naman ngtatapon ng water sa reservoir.high speed tumataas temp gauge,slow driving ok lng naman.its pure water no coolant,i will try to put coolant and see how.is changing to radiator cap 1.1 will helP?as of now im using.09
