Radiator / Overheating Problem

**jick.cejoco** · April 8th, 2018 10:34 PM

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

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

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

Ibabaw ng radiyeytor? Or takip ng radiyeytor? Hehe

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.
