High Temp after civic 99 top overhauled

[JunBargas14]

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...

[raine]

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.

maybe let me try first the cheapest option. radiator overhaul. il post my feefback after. thanks to all

that's the cheapest but that won't solve the problem. if you did not experience hi-temp before the overhaul process, then the problem is in the overhaul.

you can really have a good overhaul unless you bring down the engine.

maganda tip ni oj88 and paulgozon. check those areas first.

also, check the water pump.

Hello Po,

0J and Paul is right:

Ill give you the possible cause of overheating:

1) LEAKS - if you have leaks in you cooling system, your cooling water level will go down and will definitely effect an overheating

2) Blown/leaking head gasket - after overhauling, you should change your head gasket, plus your mechanic should know how to replace a new one. Dis he put gasket cement? silicon?... did he check the flatness of your head?
did he step by step torque tight in sequence your head bolt? remember also to return to him after break-in for the the final re-torque of your head bolts.

3) Faulty thermostat valve... the valve of a honda usually open at around 76deg C...and fully opens at around 90 deg. Never remove the thermostat valve, it is the one that stabilize your engine temperature be controlling the coolant flow.

4) Faulty Fan - Check if needed replace

5) Clogged Radiator - Check ---clean if needed

6) Wrong Ignition Timing - Premature ignition could actually increase power on high rpm's BUT, causes temperature rise in lower revs. Please set to correct stock setting.

7) Thermo Switch, This is the sensor that activates your FANs to run even your aircon is off. This triggers around 82 deg on a honda. Please check if your fan starts even when your aircon is off, this is about just over half of your temp gauge.

Finally, a new piston ring has insignificant effect on the temperature.
Lets all be technically correct about this.

I hope these helped. oh I forgot, check your water pump!

just an update with my high temp problem. nagpalinis ako kanina ng radiator sa fermin's paranaque. madumi nga radiator ko and barado. observe ko this weekend. +1 for fermin repair shop. satisfied ako sa service nila. free paint pa sa radiator ko hehehe

i tested my auto after overhauling my radiator. here is the scenario,
i travelled from north ave hotel along edsa infront of sm north going to circle.ang lapit nun.naka number 2 aircon ko.ok naman di tumaas temp...
i stayed 30 min sa circle then i travel again from circle to sm north with aircon off.napansin ko nung pumapasok na ako sa parking ng sm.umangat tempgauge ko 3/4 so huminto ako.then siguro mga ilang seconds lng back to normal din.inabot ko sa parking.i`ve check my radiator after a few minutes.ok naman walang bawas ang tubig.check ko engine oil at yun kokonti laman.mga 1/8 na lng mula tip ng stick. may tagas pala oilpan ko. so ginawa ko bumili ng motor oil tapos naglagalag muna sa sm mga 3 hrs.
after 3 hours,dinagdagan ko oil nung auto. balik sa normal.from sm north going to baclaran with aircon on.normal na normal naman na yung auto.

questions:
1. talaga bang tataas temp nung auto dahil sa kokonti na ang oil nito
2. ok na bang testing yung from sm north to baclaran. what do you think ok naba overheating problem nung car

thnaks po sa mga replies.... more power to tsikot.com

You need to make sure that your entire cooling loop is free from debris and coolant residue.

Likewise check your thermostat, if it delays the activation of your fans, especially during idle, you would experience a spike in your temps.

What is it exactly that these shops do when they "overhaul" a radiator?

Oil starvation kung kulang ang langis at hindi masyadong naglulubricate kaya dahilan rin ng pagtaas ng temperature mo at masira makina mo kung matuyuan ito at kung maayos ang oil leak mo lagi mong check oil ng makina mo bago gamitin mo sasakyan.

additional update regarding my overheating problem. I drive today at around 6pm from baclaran going to sm southmall with aircon on number 2. so far my car temperature is ok. i think my problem is ok na. to all who commented in this topic thank you very much....
