Radiator / Overheating Problem

Bumubulwak on cold startup:

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

them are different things.

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

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...

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

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.

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

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.

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.
