Corolla 1997 high temperature/overheating issues

[rodetor]

By the way, how will you know if the overheating has damaged your engine? So far my engine still running smoothly despite of the overheating issues. Im just not sure if its really an overheat since the gauge was still in the middle when then engine suddenly stops and when I opened radiator cap I can only see the hot steam but no smoke or whatsoever.

Engine usually stops when it get overheats. An overheat engine, would stall or stop it from running and your temp gauge normally would be in the up mark "H" not in between "H" and "C". Your thermostat sensor for temperature gauge maybe faulty or full of scales.

"Steam" is caused by hot and boiling water.
"Smoke"is caused by fire. [emoji4]

Checked your Thermostat valve.
Have it pulled out and inspect it.
It might be clogged and full of smudge which cause to malfunction.
If you have a stuck-up "closed" thermostat valve, and it wont "open", it can cause to overheat your engine too. Making it to produce vapor pressure,due to hot boiling coolant/water from your engine block pushing your coolant/water to the radiator and its cap and to gush out in your coolant reservoir too.

experienced the same problem, its a pajero 2000 model with 121k odo. First, I changed the radiator. Then, changed the thermostat. ganun parin. sa huli, yung hose from radiator to engine pala ang culprit. Everything is ok now at 134k odo.

The problem is the radiator hose connection to the engine. Pag masyado ma init na ang engine, tumutulo ang connection due to the rubbler becoming loose. By drops lang cya lalabas... then evaporates pag nag touch sya sa outside ng engine. So... when you check your engine, its dry naman.

total damage almost 8k
new radiator 5.5K
new thermostat 800
new hose 150
plus labor 3x

Your radiator obviously has a leak. A pressure test will show the location

[jodski]

Yup possible sa itsura nyan lulusot palagi yan

[shok]

Sir check mo lahat ng nakacircle na red.
Chances are andyan lang ang leak nyan.
Kapag medyo uminit na ba ang temp at binuksan mo ang hood parang may steam ba ang hangin na galing sa engine bay? Baka kasi may slow leak ka somewhere na natutuyo agad dahil sa init ng makina kaya hindi napapansin agad. Over a few days ubos na ang coolant mo sa radiator.

With the engine off, pressurize the cooling system to the designed pressure and observe if the pressure drops or there are leaks visible. Also pressure test the radiator cap to its opening pressure

where does one get such pressurizer gadget?

pwede ka gumawa ng mas murang version doc. hindi naman araw araw na ginagamit kaya impractical sa diyer yung mga prof kit. andami sa youtube. tignan mo ke schrodinger's box o kay ratchetsandwrenches. pero kung gusto mo talaga yung mamahalin na kit e may kakilala ako tiga pasay (hindi sa likod ha)....

ang kelangan e either tire valve or quick coupling, radiator cap, air compressor o kahit yung manual hand pump. atsaka pressure gage para imonitor yung applied pressure sa radiator.

if in doubt ako sa radiator cap e agad ko na lang na pinapalitan. no need to test na imo bukod sa manual testing (by hand) nung springs. mura lang naman.

Radiator Pressure Tester Kit

Radiator Pressure Tester Kit

4000 kesos!!??
and all it will do, is confirm what TS already strongly suspects... that he had a leak.
and this gadget won't even give a clue where that damned leak is.

at that price, i want it to include hulk hogan's finger, pointing to the culprit!

That's not even professional grade. So you think technician tools are cheap?

ah! a rhetorical question.

i'm just a car owner, not a fixit shop operator.
i don't stock up on too many tools now, as against years ago.
tanders na ako.. today, i'd rather bring the car to the shop, than crawl under 'er myself..
and i haven't seen that pressure tester in any of the shops i frequent..

but yes, i agree with you.. screwdrivers will frequently get the job done, even if they were made in china. but something more exotic like pliers and vise grip, dapat made elsewhere (USA, germany {yikes!}, even brazil).

I know, people look down on blue collar auto techs. But in the U.S. there's a handful who make a couple of six figure dollar income annually with low or no education loan to pay.

i have a colleague...
he's a physician.. but he does sileline as a mechanic...
accredited by porsche.

tekateka..
balik topic na.
baka i-ban tayo ni...

Cars in a way are diverse and more complicated compared to humans. Humans and humanoids only come in male, female, gay, lesbian, trans***uals and bi***uals. Cars come in gasoline, diesel, hybrid, hydrogen and electric powered. Piston engine or rotary engine, front wheel drive, rear wheel drive, all wheel drive or part time four wheel drive. Front, mid or rear engine, manual, auto or CVT, a whole array of anatomy and layout. With humans you know where the brain is, where the heart is etc. etc.etc.

humans come in one basic design, and with only four variants.. adult male, adult female, child male, and child female.
the rest are... political variations.
and after hundreds of years of scientific study, there has been no change in model design. not even a little bit!
and yet we still get things wrong!
heh heh.

Quick fix for overheating old engines
Change radiator
Change radiator hose
Change thermostat
Change coolant temp sensor

Done this to 3 cars. All running perfect ever since. Diy lang, watch YouTube.

Been experiencing high temperature or almost overheating of engine and the water in radiator gets emptied fast if I use my car in the morning and especially if its very traffic and hot weather. But when I use it at night I dont seem to have these problems at all. Can anyone explain this issue and help me out on what to do?

Let a trusted mechanic check the radiator and the air-conditioning system. There must be a leak. Are you sure, you check the water level? Don't rev the car too much when you start in the morning. Our hot weather is already convincing for the car to be warmed-up enough like 10 seconds. Takbo na pero syempre not that fast nmn. Ingat. Hassle yan pag tumirik so wag mo ng patagalin pre.

If you don't have access to a pressure tester, use a bright light color dye and add it inside the radiator. When it should leak, it will leave a trace
