Radiator / Overheating Problem

[dr. d]

What are the signs of radiator hose replacement? Thanks!

if you mean, the hose has already been replaced since the car got out of the factory, these are some pointers, but are not absolute:
1. the hoses don't match.
2. the hose clamps need a screwdriver to tighten. original factory hose clamps are usually simple spring clips.
3. the hose looks very new.
4. someone confessed to having replaced the hose.

but if you mean for signs, that one needs to replace the hose:
1. there is an obvious leak in that hose.
2. there are cracks on the hose.
3. the hose feels soft. (this is subjective. one has to have had some experience on how soft it should not be.)

Check your auxiliary fan at baka hindi umiikot pag nag aircon ka.

Baka dirty na radiator mo have it check and open mo radiator cap when engine on pag nabula yan malamang cylinder head gasket yan for replacement na

Sometimes, the overheat condition is not caused by faulty cooling system but rather a result of an engine condition.
The source of the heat that needs to be regulated is the internal combustion engine. If the combustion conditions are not right, the engine will overheat.
Take the condition of too lean air/fuel ratio or engine vacuum leak, if the oxygen content in the combustion chamber is too high, the combustion temperatures go high too.
In comparison, an oxy/acetylene torch, to increase the temperature of the flame you add more oxygen to a point where the fire does not extinguish. At the tip of the nucleus of the flame exists the highest temperature.

Hi Mga ka tsikot makikiride lng po kay TS... ask lng po ako regarding sa sasakyan ko. Muntik po ako mgoverheat dahil nabutas po ung lower hose ko sa radiator napalitan na po sya ng bago pero ang concern ko po ngaun eh pag inistart ko po ung sasakyan ko ng walang naka off ung aircon tuloy tuloy ang akyat ng temp. hindi na sya nababa pero kapag from cold start pinaandar ko ung sasakyan ng naka aircon ok naman ung temp. sa fan motor assembly na po kaya ang sira nun? bagong palit lang din po ang thermostat ko. tapos pansin ko rin po pag inistart sya ng walang aircon tska lang nag oon ung fan pag umabot na ng 100celsius ung temp may bluetooth obd po kasi ako kaya namomonitor ko po ung temp.

tska po kung sakali man na fan motor assembly na ang problem ok lang po ba na replacement na lang ang ipalit sobra po kasi mahal ng orig parts. Mazda 3 2004 model po sasakyan ko. Salamat po ng marami!!!

Ok naman replacement basta from OEM manufacturer preferably Japan company. Yung top rad hose mo dapat pinapalitan mo na din kasi kung bumigay yung sa baba mo, baka malapit na din sumunod yung isa. Just to be sure. Also hindi pa na barado radiator mo? Baka naman kasi marumi na din. Use coolant and distilled water preferably sa engine cooling system mo.

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?

Check radiator cap. Baka sira na yung rubber. Meaning nagleak na yung hot coolant papuntang reservoir dahil may singaw rad cap mo. No pressure= overheat

I recently had a radiator preventive maintenance check. I had a lavramon flush.

Mechanic told me to buy a brand new radiator because the head assembly is already cracked.

Brand new radiator is around P3,900 (civic). He also told me to buy a new thermostat and new radiator cap. I told him it never overheated for such a long time, why replace something not broken? He told me there is always a risk of overheating so it is best practice to change everything because it's a new radiator. Everything must be replaced as a set. He also told me never to flood the reservoir. There is a max level indicated on the reservoir. If I want to top up, it should be at that max line only.

I hope this helps you.

OT: Since you have a 97 civic, have you changed your timing belt already? You should be worried if you haven't as it can break anytime and destroy your valves. Timing belt change includes the water pump, tensioner and two oil seals. While at it, have your valves adjusted as well.

From a seemingly knowledgeable person, I would not replace the recommended parts.
If the cylinder head is cracked, replacing those parts can not fix the overheating symptom.

^You lost me there dude. What do you mean by cylinder head? (Scratch head)

It's the head of the radiator where you put the hose in. I don't know what you call it, but, according to this picture, it's called the top tank. In my radiator, it's made of plastic and it was already brittle. The mechanic told me to replace this part, but, fixing it will be expensive, might as well buy a new one.

You may want to try converting it to brass tank. Mine lasted for 2 years until my water pump broke putting unnecessary pressure because of high heat, which made my repaired radiator leak.

It’s a temporary solution. More like extracting or extending the useful life of your old rad. But if you have the money, buy brand new.

Yes, that's what I did when I had my preventive maintenance. I bought a brand new radiator, but, with the all metal top tank. No more plastic to worry about. I also had a timing belt change recently, which also included the water pump.

So, it's all worry free.

There's really nothing wrong with my cooling system actually. It's just a thought that occurred that I should do a preventive because the car has 100k on the odo. So, what do you know, I found out that the radiator is about to go because the plastic top tank is already brittle and about to burst any moment. Whew! That was close!

Welcome to automotive service technology!
In each skill or profession, there are common terms or jargon used. Use them properly. When you say head, to a prostitute it means service, to an auto tech, it means the top end of the combustion chamber of a reciprocating piston engine. You lost me.

Lmao!

So, what do you call the top tank of the radiator in Tagalog? Even the Mechanic don't know what to call it. I just point to the radiator's top and say, "Ah yung head ng radiator?" lol

[suysuy]

For me, when you say the radiator is cracked, it’s understandably the top plastic tank.

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!

Car's nowadays were really built with a certain projected lifespan. They intentionally design and built them for us to change parts or the whole cars after these xx years. Best example is our cooling system and now lately cylinder head cover, intake manifold with this plastics materials. Their premise is to reduce weight but the truth is they knew that after the defined lifespan of the machine this will be replaced. Plastics overtime tends to be brittle specially if expose constantly to high heat. Some cars was also poorly designed, where the exhaust manifold is even facing the Cooling system, ideally the exhaust manifold should be near the firewall.
