Radiator / Overheating Problem

[StockEngine]

Mine looked exactly like this with crack stress all over:



The one connected to the upper hose was the first to give in as the Mechanic replaced the hose and it broke like skyflakes. Lol! They gave me samples of the fragments and it simply pulverized when I lightly squeeze it with my fingers. I guess I was lucky to have prevented a catastrophic failure! Otherwise, I could have spent more for a tow truck and a have very bad bad day.

I guess, this is really what happens when you say your radiator cracked. More money for me as I learn more!

how old was the car? is this a toyota?

Old vehicles with brittle plastics were in part caused by the desire of many companies to use environmentally friendly parts during production ... started around 1990s ...

radiators are plastic now, mainly because they are cheaper to manufacture than metal radiators.
everything else is a bonus.

First of all, I apologize for hijacking this thread. I would create my own thread but Tsikot forum's anti-spam measure prevents me from doing so.

Bale meron po akong 1997 na Honda Civic. Nung nakuha ko po siya, naka rekta yung fan niya tapos wala siyang thermostat. May mga nabasa ako dito sa Tsikot forum at sa mga FB Car groups na hindi daw okay yung ganung setup kaya naisipan ko siya ipabalik sa normal. Kaya bumili ako ng original honda thermostat at thermoswitch.

Fast forward sa naikabit na yung thermostat and thermoswitch. Dun na lumabas ang problema. Nag ooverheat na yung kotse. Pina overhaul ko yung radiator ko kaso parang walang nagbago, overheat pa rin.

Kanina, tinanggal na lang nung mekaniko yung thermostat at binalik sa rekta yung fan. Ayun, di na nag overheat.
Sinisisi niya yung thermostat. Pagkauwi ko, pinakuluan ko agad yung thermostat at bumuka naman siya 100% so malamang hindi yun ang prob?

Btw, additional detail lang, pansin ko pala pag andun na siya sa point na nag ooverheat siya, napupuno ng mainit na tubig yung reservoir.

Any ideas or suggestions po kung ano kaya ang problema at kung ano pwede ko gawin? Water pump kaya or radiator cap? Di kaya baliktad lang pagkakakabit nung mekaniko sa thermostat?

Try replacing the rad cap

Assuming ur radiator has no micro cracks that lets out steam.

Water in radiator is usually between 98c-103c, and to prevent boiling of water to steam, it is placed under pressure. The Radiator cap regulates that pressure, excess pressure, ie:creation of steam will spill water to the reserve.

If your cap fails, its will not seal properly and suck in air, same with micro cracks. Now if air passes thru the engine, it will overheat. Thermal runaway, not enough coolant.

I think radiator tanks are made of plastic is because cores and tubes are made from aluminum.. unlike radiators before that are made out of brass.

Sir, it can be repair or Disposable na?

aluminum leaks can be fixed.
it needs special equipment and skill/training, but it can be fixed.
