Radiator / Overheating Problem

[baludoy]

why do radiators explode (or sumasabog as a fellow tsikoteer describes it in the other thread ) during hard driving ?

given our fellow tsikoteer's rig was already long in the tooth (pajero fm), why did its radiator explode while traversing the tplex at a high speed? and wouldn't it have shown some symptoms or tell tale signs before it gave way violently?

wear and tear, po. with a little bit of forgetfulness thrown in.
radiators swell and contract, with every drive.
eventually, they simply get too old and weak, and they just spring a leak, or burst at the seams.
in some instances, it was the radiator cap that gave up the ghost because there was very little coolant inside, and whatever coolant was in there, became super-heated steam.
in my case, my needle was going too hot, and when i looked at the engine bay, i saw my coolant reservoir boiling... because my aux fan was dying..

if the car used to be driven in a temperate country where water froze during the winter, that radiator may have been subjected to greater swings in temperature and pressure, and in all likelihood, more prone to rupture.

i have this qaqilala.. it was an older car, and it never occured to him to check the coolant, after two years...

good question, bro.

i have other cars, but i find the FM unusually hot. i was advised by Mitsubishi to monitor the auxiliary fan because it's almost always the cause of overheating, especially if what is installed isn't OEM. and that auxiliary fan is worth Php12,000 more or less.

My very old Mitsu's radiator burst when the auxiliary fan died.

Pressure mounts when temperature rises, too much of it result in bursting the radiator pipes

Combusting fuel heats up the engine, burn much fuel in a short span of time by flooring the accelerator to speed up to 160kph after a considerable drive, that completes the recipe for disaster. Fuel, rise in temperature, pressure mount and finally the disaster

Additional contributors would be sticky engine oil, failing auxillary fan all add up to the heat of the engine

The number one enemy of an engine is HEAT because of its built, metal. Metals liquefy under extreme heat

Radiators are made of aluminum and it melts much quicker than steel iron

I think meron ng mga micro cracks yung top or bottom cover ng radiator niya since plastic yung original na cover ng FM. Yung pressure build up ng makina since hinatak niya maigi yung rig niya sa plastic cover lumabas since meron mga crack.

Hindi niya pa kabisado yung FM niya since bago lang ito sa kanya.

^well plastic is less rigid than metal thats why its the first to crack under pressure

thanks for enlightening me

so my next question is: are there any tell tale signs if your radiator have micro cracks on it already?

given proper care, plastic-tubbed radiators can give metal ones a run for their money.
but i wonder, how much does a plastic radiator cost, vis a vis the metal equivalent?

Visual inspection is good.

With a high mileage or old vehicle that's still using it's original radiator, better to take it down for a general service and inspection. Using coolant also helps as seepage can be seen with the residue that gets left behind.

Here's what the radiator of our LC80 looked like a few years ago, when we had the radiator shop take it down for service and inspection (the LC was at least 15 years old that time).

Initial manifestation ay yung crazing the surface ng platic top ng radiator.

I totally disagree with this as far as heat resistance is concerned

But then again brackish water has a way to weaken metal structure with corrosion

Ill still put my money on a metal cap (corroded or not) rather than a plastic one due to the function of a radiator, absorb and dissipate heat generated by the engine combustion process

Mga bossing pa-help naman po. Newbie here in tsikot. Yung 2009 hyundai tucson crdi ko nakita kong may bahid ng langis yung hose coming from compressor going sa bakal na connecting sa expansion valve. Sabi nila may leak pero malamig parin po ang buga ng A/C ko kahit 1 week ko nang nakita yung suspected leak. may slight hissing sound din sa loob pag nasa #2 or 3 sya. Ano kaya problem ng aircon ko. worried lang ako baka masira compressor ko Is this really a leak? Thanks Y'all!!!

pictures.. use the tsikot android app. its easier to attach pics


you're flooding pala... youll be banned soon.

well so far wala naman akong nakitang crazing sa kanyang plastic top. i hope it'll hold-up or at least show some signs of stress first so i can replace it before it "explodes" unexpectedly

Sumabog radiator while on high speed?

His radiator cap is not releasing pressure.

Overheating Chevy Venture...
never had a problem regarding this until about years ago.

1) the Radiator, Radiator Cap, Water Pump, Thermostat are now all new. Recently flushed and coolant (Shell Reco-cool) replaced

2) both Cooling Fans (driver side and passenger side) are now all new, including the Underhood Fuse/Relay Junction Box who's terminals burnt out (the new one burned also, apparently a design flaw...resolved by soldering the failed wire directly on the pin)

3) A/C Compressor (Delphi) was replaced 2 years ago and should be still be relatively "new"

These worked for a while until recently when it began overheating again!

Wizzard recommended getting the ECU/PCM checked by "someone in Banawe" coz they find nothing wrong with the wiring. Apparently the computer is not closing the ground on the relay.

They temporarily setup up a toggle-switch that directly hooks up the power from the battery to the driver-side aux fan so I may drive the van and not need towing. It works but of course the "Check Engine" warning light switched on.

Has anyone encountered a similar problem before???

*mulawin00
coolant temperature sensor na check na sir?

not that I know off po. that's a good idea nga. baka maling data na ang nakukuha ng ecu/pcm

Makiki ride na po dito sa thread, nag pa overhaul po ako last July ng rad ko tapos napansin ko na nabawasan yung coolant ko sa reservoir check ko po meron leak sa rad ko. Ayaw ko na po ibalik don sa pinag paoverhaulan ko para ipabaklas pa ulit. Balak ko na po na palitan na lang ng bnew. Di naman po ako lumalayo layo dito dito lang ginagamit yung auto. May masasuggest or refer po ba kayo saan ako pwede makapag canvass ng mga radiators and thermostat? Toyota BB po ride ko. Salamat po.
