Radiator / Overheating Problem

[batang_angas]

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.

Thank you po for your input. I tried observing the temperature for a while but so far it stayed at the normal operating temp.

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

Maybe its as simple as a faulty radiator cap.

A friend had this intermittent overheating issue on his innova. After a few visit to his suking shop that found no problem, i opened the radiator cap only to see that the spring rusted and fell to the radiator

Replaced it with a new cap. No more overheating

Thanks for the input sir! Much appreciated. I will bring the car to my mechanic on Monday to see if there are other issues. But so far the temp hasn't risen above normal operating conditions.

what was done to fix the problem?

Actually I did nothing sir. Which really bothers me. I'm not sure what caused it to rise to the point of almost overheating that's why I'm trying to observe the car if it would repeat the same thing again, but so far everything is back to normal. [emoji848] But I'll have my mechanic to have a look at it, may be its just a faulty radiator cap or a water pump problem. I'll let you know once I have figured it out.

perhaps it is the fan.
it may be rotating, but it is not rotating as fast as it should.
if one drives long enough, the coolant will overheat.

i had problem with my sentra before. the fans were working, but when i compared the volume of air the old ones were pushing, to the amount of air new fans would push, i replaced my "still-working" fans. that solved my overheating problem.

another possibility is clogged radiator tubes.

but i finally got to the fans, after ruling out the other possibilities.
it was a tedious process spanning almost a year.

^ Doc Is there a sure way to determine the slow but progressive deterioration of the operational capacity of the rad fan?

I regularly check the coolant reservoir of my fd2's rad and i notice there's a gradual decrease in the amount of coolant in it in a time frame of over several months.

do what you gotta do so you can do what you wanna do

it's like growing kids, i suppose.
if you see them every day, you won't notice their increasing height.
but if you see them only once a year during mano-po-season, you will notice it, that is, if you remember how short (or tall) they were the previous year..

but if i were to hazard a guess... i probably would suspect it if my temp needle goes beyond what i normally see.
in my car, that would be beyond the halfway mark to, say, at least 5/8 , in heavy traffic.
my other car kasi (no aux fan, but a direct-drive with silicone-operated clutch), or my sentra when it was new, kahit one hour in standstill noonday traffic, the needle still kept a little under halfway.

in my instance, i thought the blow was strong. only a side-by-side comparison convinced me otherwise.

in retrospect, it was my over-reving temp needle (won't work with some cars' idiot temp warning light), and the loss of coolant, both in the radiator and in the reservoir.
the soundness of the old-timer's advice hit me, when i actually saw steam bubbling out of the reservoir. it meant that my coolant in the radiator wasn't getting cooled, and was bubbling out into the reservoir, resulting in overheated reservoir coolant, thus resulting in bubbling.
i expected similar symptoms with a clogged radiator. but as i know for a fact that my radiator had recently been cleaned...

update lang ..

marunong nako magbaklas at kabit; plus minor repair ng radiator

naka 2 backjob na kasi ako dahil sa top leak, gilid ng dugtong. after kasi kabit ng rubber gasket, nilalagyan ng sealant (gasket maker), which is OK sana kung sakto pa yun rubber; so nilalagyan ng gasket maker. ginawa ko, tinanggal ko yun rubber gasket, then gasket maker nalang from pioneer. so far 3 hours na of driving (2 hours during sunny weather), wala pa leak.
ok lang sana kung distilled water lang gamit ko, kaso sayang mahal na ng coolant * 380php per 2 liters (IIRC)

[ninjababez]

yun rubber rubber gasket kasi, binabalik nila tapos lagay ng gasket maker. kaya siguro nagkaka leak?
