Overheat

[Drumz]

Nissan Sentra 95 Series 2- M/T B13

Radiator Overhauled
Cylinder head gasket replaced
Hoses replaced

But a while aago when I turned on my air-con after 1-2kms it overheated. Anything else that I need to look for that could be causing this?

[niky]

Full overheat, or just a small rise in thermostat reading?

If it only happens with AC on, check your auxiliary fan. It might not be triggering. But that alone should not cause overheating.

over-heat. as in kumukulo yung tubig sa reserve. tapos sobrang taas ng menor habang umiinit, yung hindi mo na kailangan tapakan ang silinyador.

Hindi dapat kumulo ang coolant. One possibility is you have abusted head gasket which makes the exhaust gas escape through the cooling galleries, hence you have that bubbling effect. Pag ganito situation, uubusin coolant mo through the relief line. Yun lang kasi escape route and then issunod mga coolant hoses mo. Patingnan mo kaagad sa nagoverhaul ng radiator mo.

Sorry, kapalit mo lang din pala ng gasket. Baka hindi tama ang lapat ng head. A simple observation will prove the above. Kung nauubos ang coolant and if you cannot see any other leaks that causes it, it might be as I explained above.

check your aux fan if it will trigger during overheat. If not, something is wrong with the fan or its socket connector.

I have experienced poor contact on the aux socket connector on my Lancer EX, same scenario after about 10 KM it will overheat and the aux fan is not working. Replacing the connector has solve the problem.

Napansin ko lang nangyari ito nung nagpalit ako ng compressor ng air-con. Pinalitan ko na din ang hoses saka yung cover nh waterpump ata yun. Pero sabi nila yun yung waterpump.

Pag naka-A/C lang ba nataas temp? Baka naman nag-high pressure iyong a/c mo.

Panong nag high pressure? How to fix it?

it means barado or madumi condenser mo sir....

[Drumz]

Pero nilinis saka nag flush kami nung pinalitan yung compressor sir e. We also changed the valve dryer saka yung lalagyanan ng freon.

[deafault]

Check the condenser fan. Baka inefficient na din yan

pag hindi ka naka-aircon and still nag ooverheat,

stuck thermostat perhaps?

[Drumz]

Tangal na po thermostat sir. Top overhaul na pinagawa ko just to be sure.

some cars overheat if the thermostat was removed. try installing a good working or new thermostat. if the condenser was clogged or restricted, the condenser will be cool or cold (simulated expansion valve)

The overheating has to do with your radiator mostly and its adjacent sub-systems.

Radiator overhaul where? How?
What's the condition of your radiator fins?
Water pump state?

[Drumz]

Radiator repair shop ko siya pinaoverhaul. It was disected as in bukas talaga. They de-clogged it tapos checked leaks. Fins are still intact. Water pump is still working. Actually I had it replaced.

[Drumz]

Is the condenser the black thing where the freon is placed? Normal ba na nagpapawis ang tubo?

[EVO-V]

The condenser is the aluminum radiator looking thing in front of the radiator.

I'm assuming its an original radiator you have or replacement na ito? If so how many years?

The problem with overhauling is that they really don't solve the problem of scaling on the tube walls, especially if you have run the loop without any coolant.

No amount of scraping will actually rid the radiator tube walls of the calcified corrosion residue that insulates it.

Doing so in fact makes it prone to damage and leaks.

Thing is A/C on or off, your car shouldn't overheat -period. Even if your A/C is working fine, then it certainly isn't the problem.

In this situation I would surmise that if and when your A/C's condenser is ejecting heat to your radiator, your radiator fins are themselves clogged or simply oxidized (say its over 10 years old) or has been overpainted, that your radiator simply cannot reject the heat.

Always remember, masmura ang radiator kay sa overhauling.

Here's another thought. Your engine's cooling channels maybe clogged already.

newbie here, ill be needing your help masters

my nissan sentra 94 ex saloon, pag nadrive ko na siya ng mga around 4hrs with aircon, temperature ng oto lumalagpas na sa kalahati eh, kaya ang gagawin ko is ipapahinga yung oto, for about 30mins, after that ok na ulit temper niya, tingin niyo guys ano kaya prob ng oto?? somebody help po.. normal ba yun sa cars? na tumaas ang temper pag almost 4hrs driving na?
