Weird substance inside radiator

[RENESIS VIII]

Gain experience become sifu now......

Not really. Among non car people can say roughly explain basic stuff. But at zth, just low level member only among masters and sifus.

You din't bring your radiator to any shop to get it opened and flushed?

Your old engine got kapow is because of this temperature issue or other problem?

the flushing was done at the shop itself.. which is where we discovered the thermostat problem. after removed thermostat oso same shit.. shove in tap water for super long and still lotsa gunk.

old engine kapow due to distributor issue as well as my own stupidity.

Hi. Had that same problem. The gunk was from the thermostat innards. Mine felt like melted wax to the touch. Flush, replaced thermostat. Solved my issue.

If shiro-san came in earlier, probably topic won't be 15 pages......lol

Any idea where those gunk originated from? The radiator itself?

Distributor problem can kill the engine? I need to be more careful with that from now on.

Oh, so you mean the thermostat somehow melted or something? Yours is Wira 4G15 too?

Haven't seen him before despite having 3000 posts. Another old timer sifu has appeared.

Yah! but exact same problem as yours......lol

To be honest, thermostat problem is considered uncommon among overheating issues right? A lot of threads where I searched about temperature rising, mostly would be clogged radiator, leaking hose somewhere, fan not working or too slow, radiator cap faulty or gasket kong.

my gunk? probably rust build up or something.

distributor yes... coz i had mine changed and without setting it first, i redlined the engine and kapow.

actually thermostat can be a common issue for overheating. mostly due to thermostat jammed shut... and water cannot flow hence overheat.

or like my avanza, thermostat leaking.. radiator empty of water and didnt notice....

Did those gunk or rust ever returned after the radiator change? Because if it is rust, probably it came from the engine block? But maybe that was from your old engine.

Now that I learned about thermostat, it could probably be one of those reasons that I hear about old cars overheating and made them unable to travel for long distance. Some of my friends who had old cars at their home said even though no leakage and radiator went for flushing, the car still got temperature issues. Probably thermostat if that is the case...

i never changed radiator... old block had rust... new block had rust... most definitely from current radiator.

after coke flush radiator water has stayed clean

About two years ago, I had an overheating problem caused by the thermostat jammed in closed or partially closed position. Changed the damn thing and never had any overheating issue anymore.

 

[lsm1991]

ehh the gunk is the thermostat itself!?!?
thats weird!

That is why you need to check out the problem first. Different issues different parts having problem. That is why after you posted you follow up problem, I ask you to check the thermostat first.....lol

Sorry, was mistaken earlier. So, the radiator is actually rusting I guess?

B16A?

How did a thermostat create such amount of gunk puzzles me... Or the same amount of gunk had been circulating over and over.

Good thing I decided to ask here and continue giving detailed update about the problem. If not, hard to solve the problem now..

Meanwhile, today I was stuck with power window problem. Window jammed and got cracking sound when trying to wind up and down. Is the same window on the front passenger side where I got the motor replaced 2 years ago. All these while, the window is okay without any hesitation in winding up and down but just today it had this cracking sound like scraping against something.

 

[g4i8y0t]

B16A?

Yup, this current engine.

 

[sweelt]

renesis, i face this problem with power windows. Still use hand to push up.
is it safe apply some lubricant on the rubber ? suspect rubber is the culprit.

Madman is also using B series. But I'm not sure which one already. I think is B16A.

Tomorrow I need to bring it to check. Just now to wind it back up, I need to wind down and quickly wind up again and it moved slightly higher each time. Keep on repeat and doing that until it reaches the top.

 

[mADmAN]

yeah im on B16A... n yeah i think my rad is rusting ahahahahah

What radiator are you using? I'm not sure what materials are used in making radiator nowadays. I know old cars uses copper and aftermarket ones are usually aluminum.

For rubber you can apply some silicon grease
