Overheating

[huytek]

Hey,

My main Overheat problem I think is that my coolant goes from my radiator to the reserve tank and it overflows. After driving I stopped to see any leak, and I noticed the problem was that the coolant was gooing to the reserve tank... and overflowing...

Did you guys know what is going on... It is just a radiator problem .. any suggestion?..

The fan does still go on, and the temp does go down when i boot it as more air is sucked in from the intercooler

Thus, main problem is that when on idle, the temperature goes up, and the fact that the coolent was going to the reserve tank.

Any help would be greatly appreciated

Thanks,

Huy

you might have a head gasket problem.

[huytek]

Im thinking it might be that as well..
as there is some power loss...but i was hoping that was due to the overheating causing everything to lag
how would i do a test?

[jdmTYPE R]

pressure test on your radiator will tell if your headgasket is gone

[huytek]

yeaa
i just read up on a few ways to test it out
its strange tho..the car ran completely well yesterday withought any overheating problem at all
and most of today as well

estimates on the cost of replacing the head gasket?

[NEED VTEC]

check your oil, if its milky your head gasket is gone, maybe your thermostat is playing up

[NEED VTEC]

check your oil, if its a bit milky you head gasket is gone,maybe your thermostat might be rooted

Does it constatly fill the overflow bottle and not return back when cold? If you have not overfilled your coolant in the first place I would make sure the Radiator cap is functioning correctly first.

If thats fine and it continues to fill the bottle and not return back then I think your head gasket might be blown from water channel to a Cylinder. On the compression stroke it is forcing air into your water system and in turn pushing your water out and overfilling your bottle.

Take it to a mechanic to get it checked out.

Thanks for the replies!
Well i have checked my oil..and it isnt milky in any way..everything seems to be normal in regards to that...

And the coolent does return back to the radiator from the reserve tank after the car has cooled down...

So at the moment from what i have checked, it doesnt seem that i have blown my head gasket...

so could it possibly be just the simple problem of the radiator cap?

I suppose ill replace that, just to try it our anyway

[DLO01]

If the coolant is returning back then the radiator cap is fine, as it should work both ways.

You sure you simply have not 'over filled' your coolant past the full line on your overflow bottle when the motor is cold?

Coolant/water expands and if the bottle is overfilled then it will overflow when engine is warm.

Check it when cold. :thumbsup:

Check the thermostat. You might want a cooler opening therno to help move heat quicker... My temps went up also but i changed the thermostat and it holds ok temp now

Checked that you don't have any air bubbles in your coolant piping.

[silver_screen]

hahah i was thinkin the exact same thing when i read it...

Bleed ur system, sounds like u have a big air bubble :)

[silver_screen]

ahh noticed u were in melb... mayb u should come down so i can have a look @ it :P

[huytek]

yea it just occured to me this morning that it mite be an air bubble as well..

meaning i should let the motor run for a but without the radiator cap on? ("burping the car")

well silver screen..you can check out my car if you dont mind lookin at a rice bucket =)

and by the way..thanks for all the replies

[silver_screen]

rice bucket?? lol doesnt bother me... a cars a car.. where r u located???

chances are it has a bleeder nipple.. from memory i think its on the top radiator hose where it connects to a metal pipe.. there should b a bronze lookin nipple... its a 10mm.. u gotta open it up while ur puttin water/coolant into the rad so air comes out.. when uve got fluid comin out.. close it.. run the car and as the temp rises, open it up so allow trapped air come out.. do this till the car has reached operating temperatures.. usually takes around 5 mins... or wait till the fans come on.. check it one more time and u should be rite... thats considering my memory serves me right on the nipples location ;)

if u have any worries just come past and ill check it out for u :)

[egSi]

u can have a fecked head gasket with no 'milkyness' in the engine oil at all.

mechanic can do a test which takes 5mins to see if your head gasket is at fault

[DLO01]

Yeh thats right, like I said blown gasket cylinder to water channel, pushing air in your water system.

But you said that the coolant 'is' returning back from your overflow bottle when cooling down. Where if you had air in your system the coolant would not retrun back because of the compressed air in the system.

Stop messing around take it to a mechanic, hes got all the right tools. :thumbsup:

D-series?

Headgasket for sure. Easy test, Drain overflow tank to very low. Hit fullbost a couple of times, pull over. Take overflow tank cap off and smell, observe mixture. My guess is u will see black particles and the smell is very exhausty.

[Weq]

oh yeh, and because of the open deck, u can easily blow a headgasket under boost and not get any other symptoms. Over time it will start to overheat during normal driving as the problem gets worse. Very rarely will u see a honda mix oil/coolant.

[silver_screen]

rare my ass, ive seen it millions of times..

[RCS 20L]

Thermostat i say... maybe stuck... get a new one and try... or take out and put in boiling water to see if opens up...

[Limbo]

I'd try the radiator cap first, could be just the spring has worn and is letting out the water too early

[silver_screen]

I would stop giving out advice that costs money... What he should do is drive his ass to my place when ive finished work so i can have a look @ it

That way we can determine whether its a cap, or a thermo or a head gasket (which i really doubt) or air bubbles (most probable)

O rly? ;)

Weq has some good advice you can take on board, try doing that before you do anything, wont take long and at least then you may be able to rule out a few things.

[barefootbonzai]

does any coolent leak from your timming belt side?

[VTC-8OY]

headgasket i rekon... happened to mine...

[huytek]

Well after all this time...yup
it is the headgasket

Is there anyway to strengthen it to prevent it from future problems?..Since i gotta get this fixed anyway

And arnd wat prices am i expecting?

[saxman]

have some arp headstuds installed in place of oem headbolts... and you may want to have the tune on the ecu looked over(assuming you're using a tuned ecu)... generally a blown headgasket on a turbo motor is a result of a tuning problem

Just because u do an aprenticeship, doesnt mean u are knowledgable about cars. If i was u, i would stick to oil changes and thank your lucky stars most honda's are over-enegineered that u can get awya for 15yrs in the business and still not know the difference between a camshaft and a crankshaft.

Sorry to hear dude.

You'll be looking at around $800-1000 at mechanic shops/garages. If doing it youself which i don't recommend $200 max.

Don't think you can strengten it :o:o mayb replce it with a honda headgasket ?
