Mabilis uminit ang makina.

[jozin]

Hi everyone,

Nag palit ako ng piston ring. Napansin ko medyo mabilis uminit ang makina ko kapag traffic kahit gabi. Pero kung mabilis na ang takbo, bumababa uli ang temp. Normal lang ba ito kung bagong palit ang piston ring? Napansin ko rin na namamatay ang makina kapag medyo mataas na ang temp ng makina. Mabuti at napapaandar ko rin agad. Ano kaya ang problem ng makina ko? Ano kaya ang dapat kong gawin? Toyota DX '83 ang kotse ko.

I appreciate any help. Thanks in advance.

baka sira or hindi gumagana maayos aux fan mo? kasi pag tumatakbo ka mabilis yung hangin na pumapasok sa hood mo, forceably na papadaan sa rad mo kaya nag napapalamig yung radiator mo.

pwede rin may problema water pump mo, kasi yung water pump mo naka kabit yan sa crank shaft pulley mo, pag bumibilis takbo mo, bumibilis din ang ikot nun, so tataas yung flow ng tubig kasi mas mabilis bumomba ang water pump kasi bumilis ikot nya.

kung barado ang radiator mo at water jackets ng engine blocks mo, sigurado kailangan ng water pump mag doble time para ma padaan ang tubig

common na ginagawa apra dyan.

1. pa check water pump
2. palinis radiator
3. pa check aux fan
4. idling mo pa check mo. baka naka 2000rpm idling mo hehehe
5. F/A mixture umiinit makina pag hindi tama ang F/A,

[badkuk]

hmmm..check mo rin ung rubber hose fittings/clamps sa radiator

[sirkosero]

mechanical fan pa ba yan? kung oo, check the fan itself or yung tension ng fanbelt...

[jozin]

Mga bosing salamat po sa mga inputs ninyo. Ang dami ko po na-take note. Try ko ipa-check ang Aux fan, radiator, F/A mixture and water pump... hose and belts ok nman. I'll try to schedule it this weekend. Di kayo masyado nag comment tungkol sa bagong piston ring. I guess it doesn't really contribute masyado sa heat even if bagong palit.

Thanks a lot. ang more power sa inyo.

Baka tight fit ang piston rings mo, baka lang or the cylinderhead gasket may be damage due to over tightening.

[jasonub]

break it in the tightness may have something to do with it. in one of our vehicles that was newly overhauled, it was overheating when we put some load on it (truck)

when there is no load no overheating (idle)

we checked everything water pump, hoses, thermostat stuck, you name it we checked.

suddenly it stopped overheating. the point is you should not let it overheat. when you see its about to overheat, cool the engine down by waiting for it to cool.

good luck

dude, dont use mineral water.

use DISTILLED water.

[kimpOy]

additional tip kung tatangalin mo ang radiator pa tanso mo na ang ilalim and top na rin.

kimpoy
ano advantage ng tanso radiator top n bottom?

[afrasay]

Kim, si cody ba yun avatar mo? laki na ah at malago na ang buhok :D

Use Distilled drinking water not mineral water. Kaya nga we do not recommend tap water is because it contains solids.

[jozin]

Thank you sir sa clarification. Any explination why distilled water is good for the engine?

Check the link http://www.928oc.org/tip/tip514.htm and read the whole article. Hope it answers your query.

[OTEP]

Simply put, distilled is good because it has been distilled and the solid particles have been taken out.

Those solids can stick inside the radiator, cause scaling, and eventually foul the system.

pag bago overhaul or top O/h makina mo,ang susunod na mangyari dyan is clogged radiator tubes.di maayos pag tangal ng head gasket mo-kinuskos then pumasok sa jacket ports.Normaly nangyayari yan pag paspasan ang trabaho ng mekaniko.

I've already experience that.maybe maybe maybe ganyan din ang nagyari.

I suggest to check all the components of your cooling system.marami kasing dahilan yong overheating problem.

[jozin]

Sir Leinahtan,

Salamat sa link na bigay mo very informative. From now on I'll try saving rain water for my radiator (syempre yung malinis).

sir jeegoogs, salamat po sa input mo. Yan talaga ang cons ng nagtitipid(di kayang dalhin sa casa). Next time sana maka ipon ako ng malaki-laki para madala ang kotse ko sa casa or sa shop with reliable and dependable mechanic.

Salamat po uli.

if you done already lahat cnbi nla at gnon prin bka ala s timing, pg dlayed timing hirap ang engine taas temp mo,pwede rin my warp cylinder head kung matagal magcooldown at mbilis mghigh temp at high speed pwde rin improper torque and sequence ung pakbit ng head ng mekaniko
