Radiator / Overheating Problem

[mina_nuka]

hello Guys...
Been experienced over heating issue's on my toyota 5k engine recently,nagtatapon ng tubig sa reservoir pag na stuck sa traffic,pero di naman nabulwak tubig pag nirerev pag bagong start....so i decided po na pacheck sa mechanic and he diagnosed na need palitan cylinder gasket.. .so since ayoko lumalala problem sabi ko GO lang at palitan na need ng palit since old model narin toyo ko...
so eto po mga napalitan:

cylinder head gasket
manifold gasket
valve seals
sparkplugs
Piston rings

after mapalitan lahat,eto ang scenario...
nawala overheating issue been stuck on a heavy traffic almost 2hrs nov.1...then for me thats a good sign kc steady sa 1/4 ang temp gauge ko. . .
but out of curiosity,from cold start open ko radiator cap,okay naman ikot ng tubig,pero nung nirev ko dami tumatapon pag ni rerev...

ang tanong ko po..okay lang po ba ang ganun since hindi naman na tumataas ang temp kahit traffic??
worried lang ako kc dati pag cold start hindi naman nabulwak tubig pag ni rerev..

your "mechanic" removed the thermostat

your "mechanic" removed the thermostat

Why is it that they insist on removing the thermostat? I remember when I had the radiator cleaned, that guy kept on suggesting to remove it. I just smiled back.

Maybe because the main concern is overheat based on the gauge which relies also on the thermostat.

By removing it, the only indicator will be gone and the clueless owner would be happy since di na nagooverheat... Sa gauge.

killer smile ka saw kasi bro [emoji23][emoji1787][emoji869][emoji869]

iba parin thermostat sa "temp diode" bro. sa vios kasi napansin ko nasa thermo switch (aux fan auto switch) din yun trigger ng high temp reading.

kaya lang nila tinatanggal thermostat para umikot agad yun tubig (cmiiw). ang downside nito, matagal ma reach optimal operating temp. ganun din nangyayari pag always ON ang aux/rad fan diba, dahil natatago kasi yun totoong sira ng auto bakit nag overheat.
yan yun mga shortcut ng mga old "schooled" mechanic. si mang jorge ng banawe, ayaw din sana ikabit yun bagong bili ko thermostat. sabi ko nalang, sayang at nabili ko na. ayaw ko rin kasi ma offend, dahil ok naman (so far) yun gawa nila sa radiator ko.

btw lahat yan dito ko lang na pickup sa tsikot, tpc, pdvd and viber messages nila bro vinci, egan and others.

Cars with two way thermostat will be overcooled. Hindi nga naman mag overheat, overcooled naman.



Cars with three way thermostat will overheat if you remove the thermostat.




Ito talagang mga engineers hindi nakikinig sa mekaniko o sa parts replacer. Tsk tsk tsk..

so what does the thermostat do in a basic engine?

in the tropics, the thermostat's function is to have the engine reach working temperature faster.
when the engine is cold, the thermostat is closed. the coolant in the cylinder block has nowhere to go, and therefore heats up fast.
as the temp increases, the thermostat opens up. this allows the hot coolant to leave the engine block and go into the radiator, where it is cooled. it then goes back to the engine, where it cools the latter such that it does not overheat.

so why do we want the engine to reach working temperature fast?
the engine is more fuel-efficient at working temp.
it is also more efficient. period.

so what happens if the working temp is not reached fast?
we spend more for our fuel. just a bit. but more, nonetheless. and, it spews out more pollution.
also, the engine is less efficient. less oomph.

so why does mechanic recommend thermostat be removed?
it's one less part to malfunction.
and because he does not know why the designer placed it there in the first place.

heh heh.

ok na for a few days yun temp. flushed distilled water and poured in toyota long life coolant [emoji869][emoji869]

Excellent explanation on the function of thermostat. This should be helpful for those who are starting to learn the basics of car maintenance.

The old school mechanics who would even say that it will run without it, can be ignored politely.

I've had overheating problems last month. Now the initial observation was, its a cyclinder head issue since nauubos yung fluid sa radiator at reserve at bumubulwak nung tinest yung flow ng coolant/water. PinaLavramon ko yung engine tapos nung tinignan yung radiator sinuggest na palitan ko yung radiator. So upgraded na sa 2-row aluminum radiator at di na nagoverheat pero nung pinainit to test kung nag circulate bumulwak pa din. My question is, should I be concerned that its a cyclinder head issue since di nag overheat at stable na yung coolant supply, na di nag drain or apaw at wala naman yung one of the signs na milky white substance sa oil cap?

[ninjababez]

^bro try mo daw compression test. not really sure how it would help, pero nabasa ko lang hehehe
antay natin mga tips ng iba

1. are you overheating, as evidenced by your temperature gauge?
2. are you losing coolant?
3. are you both overheating and losing coolant?

them are different things.

[mina_nuka]

It can have perfect compression test result even if the coolant is leaking into the combustion chamber s.


The preferred test for this concern and is more conclusive is a cooling system pressure test.

[box_type]

if you're not overheating or not even getting high temp on your gauge that shouldn't be an immediate concern. Now, question is gaano kadami yung bumubulwak sa radiator? afaik, kung hindi naman masyadong madami or malakas ang pag bulwak normal naman may bubulwak dyan pero dapat konti lang lalo na kung sarado pa thermostat at the time of testing, paki correct na lang mga master...

Bumubulwak on cold startup:

1. Thermostat valve was removed by siraniko
2. Thermostat valve is stuck open

Before the old radiator was replaced, check on 3 but not anymore. I'm just concerned when I was told it might be a cylinder head issue since bumulwak yung tubig but that only happens when the temp is extreme not when it is cold

nung nirev kasi parang malakas yung bulwak but as the moment the temp is stable and the rad and reseerve does not run out of coolant. No milky white substance also on the oil cap per those guides I'm seeing online for a busted cylinder head/gasket

ito ba yun mga bicycle pump type na na DIY online?

Hello po again. I'm having temperature issues po with my 03 Honda City Type Z. The temperature is getting high so I stopped at the nearest gas station to get water to cool down. There were some bystanders who helped me out to figure out what's wrong with the car. They are saying that the radiator was clogged.
Here's what I know so far:
-the fans are working fine
-I'm not losing coolant and water from the radiator

If the overheating just happened, maybe the coolant level was low or maybe the thermostat was stuck closed. At that age I would replace the thermostat whether it still opens normally or not.
