High Temp after civic 99 top overhauled

mga sirs normal lang ba na paminsan minsan tataas temp ng car after top overhaul at palitan piston ring? especially kung on ang aircon ko.
accrding to my mechanic, normal lang daw kasi masikip pa daw ang pistong ring... is it true? any comment...

na total brake-in na ba yan makina mo after palitan ng piston ring at ng i-top overhaul ang makina mo?

kasi kung na brake-in na yan nag ha hi-temperature pa rin sya abnormal yan.

pero kung totoo ang sinasabi ng mekaniko mo masikip pa ang piston ring mo maaari pa, kasi ang piston ring kapag bago ay may katigasan kung kaya ginagamitan ito ng piston ring compressor bago ipasok sa cylinder ng makina mo kapag ang piston ring mo mismo ay nakakabit na sa piston mo.

dahil nga may katigasan pa ang piston ring mo ay medyo wala pa itong gaanong gap at masyadong nakadikit pa ito sa cylinder sleeve kung kaya sa oras na kumilos ang piston mo ay parang nag cecreate ito ng friction na nagiging dahilan ng pag-init ng makina mo.

napansin kong tumataas temp ko ga 300kms na natakbo ko until now na 700km na.especially kung nakaaircon ako. normal lang ba ito since dipa daw complete yung break in ng auto?

puede yun kapag hindi pa complete brake-in ang makina mo kasi nga masyado pang nakadikit ang piston ring mo sa cylinder sleeves mo.

saka basahin mo ang OEM manual mo kung ilang kilometers ang kelangan buohin mo para makumpleto ang pag brake-in ng makina mo.

salamat sa mga inputs bro...

ang pagkakaalam ko dapat ipa oveerhaul mo rin ang radiator mo kasi yung mga dumi matatagtag at magbabara sa radiator mo. 350pesos ang rad overhaul .

tama rin ang sabi ni Raine dapat ipa overhaul mo na rin ang radiator mo dahil sa tagal na rin na panay tubig nawasa lang ang nilalagay mo ang may kala-kalawang na yan medyo ang mga ilang butas sa rows ng radiator mo ay may bara na.

Wala dapat kinalaman ang baging piston rings sa overheating... unless kung out of spec. Kapag bagong bili auto, wala namang overheating problems so hindi bagong piston rings ang cause.

Troubleshoot yung thermostat, aux. fan(s), timing, A/F ratio, klase ng coolant na nilagay, etc.

I believe in OJ88, na walang connection yun piston ring (if within specs) sa overheating. An increase in temperature when the a/c is turned on, is a symptom that something is wrong with the cooling system or the engine is producing more heat due to wrong timing.

First thing to do is for you to check for possible leak, look at the radiator hoses, bypass hose, water pump (between alternator and front crank pulley). These hose might be torn when it was remove.

Second, have a look at your fan with engine running and a/c turn on, and observe them, they should be running fast and large volume of air is expected. In the eyes of an expert he can notice this difference.

If not leak is visible, Honda's radiator is small compared to toyota, mitsubishi, so any mistime will definitely show with a/c on, try checking the timing, using timing light, or recheck the timing marks on the crank pulley and cam sprocket.

Another potencial problem with honda is when you remove the thermostat valve, the by-pass tube should be plug, for around 15-20 percentr of hot water will recirculate back into the engine. Most of the mechanic will say that we don't need this thermostat valve. But this is an important part of the engine. But it could also be the cause of the overheating if it does malfunction or remove.

Radiator overhaul is my last option because in our place, those radiator shop charges about P800 - P1,000 for an overhaul/Cleaning of radiator.
