Radiator spare tank overflow

[Jakk]

Nowadays i encounter this " Spare Tank Overflow " problem. Hope sifu sifu here can enlighten me.

Car: Prelude H22A

What i did:
swap port and polished head, guarantee no bengkok by trusted friend.

Bleed the thermostat housing everytime after top up water.

what are new:
- head gasket
- radiator cap 1.1bar
- thermostat ( low temp )

what are halfcut item:
- radiator ( no clog )
- thermostat housing
- IACV ( Idle Air Control Valve )

what will happen:
i fill up 50% of water into spare tank, and fill up water into radiator.
then i travel to cheras for work, and come back to subang, pergi balik around 70km, stop and go traffic + highway.

then i open up my spare tank and see, it is 90% full, and for my radiator, i need to top up around 700ml of water.

So far not yet overheat.

After i got my car back, i drove the car for 1 week without knowing such problem, still no overheat.

Just wondering why.....

Update (25 Oct 2012):

When i crank start when the engine is totally cold down, water in radiator wont burst out.

When i crank start after the engine is warmed up, water in radiator burst out.

I crank start the car and idling without the radiator cap, when i off the engine, the water burst out.....

did u bleed the radiator?means to throw out bubbles from the radiator...u must put water into the radiatortill full..then start engine...wait and see..if the water decrease..top up again..then after bubbles out...then u can put radiator cap..after that u can full water spare tank.....

Is your fan running..? try swap radiator cap for testing...

After i read ur comment, i went and did radiator bleeding, is it normal that the water keep spilling out from the radiator?

btw, it becomes stable after a while....will give it a test run tomorrow.

Thanks for ur info !

When did you check the expansion (spare) tank? Best to check in the morning when cold. If you check after driving, the radiator is hot, so water goes to the spare tank, when radiator cools down the water should go back to the radiator. If it does not go back, check the radiator cap rubber, maybe worn and not tight, so instead of sucking back the water, suck air only....

i check in the morning and after drive. Both filled up. Gonna pay attention on radiator cap now...

Btw i just bleed the radiator, gotta test it for few days.

My radiator cap is new, 1.1 bar. Bought at spare part shop. Itu ok ke? =X

Thanks for the info!!

is that problem came after head swap?..before..? if head sure not bengkok..how about block..did u check or resurface its.this kes always happen...or u oso can try check got any water remark at water pump,pipe that always rubber ring failed..

yea, came after head swap.

But not only swapping head.
I changed radiator, low temp thermostat, IACV, and thermostat housing, so i am not sure which 1 causing the problem...

for the head, i trust my friend becoz he is mechanic himself, and also reputed member / adviser / seller / DIY-er in our club. Although the mechanic says the problem from the head... ( Cannot say the head 100% no problem la, but the % is low )

as for the block, yea, i saw my mechanic gosok the surface with 1 thing but i not sure what is it, but the surface become kilat kilat after that. =X

Will pay attention for water mark, thanks!

 

[spoon civic]

try trouble should..but normally when got overheat..better get the engine kosong meyh..as for skimming block and head the cost are quite high too right?

 

[aalto]

If the water isnt boiling (bubbly) after a long drive (you'll hear air bubbles going into the resevoir if its due to warped head), it should be OK...

Or just do a startup test to see if water jumps out the radiator...

Are you losing a lot of water? From what I read, you need to fill radiator but the expansion bottle have more water, right? Then it shows that the water is not returning.
If you have water loss, you can ask mechanic to do pressure test also.

For the gosok until gilat, that is cleaning and polishing only. Like waht bro. spoon mentioned if either the head or block is warp, you may need skimming to level the 2 surface for a good tight fit....

 

[peeche]

check easy and cheap things first - spare tank.. return hose.. radiator cap.. radiator hose including small hose attached to throttle body.
if still losing water.. check thermostat.. radiator fan speed.. radiator servicing.. water pump..
if all ok then it should be your head/block or gasket.

try this. :wavey:

if go for skimming, the compression will become higher, and normal temp for water will slightly higher.

according to my mechanic.

is it true? ><

engine kosong, red top!

I didnt hear any boiling sound, nor overheat.

for the start up test....i do it under 2 different engine temperature.

Totally cool down - no jump out from radiator.

Warmed engine - jump out.

Some mentioned can fit in thicker metal head gasket....
