coolant issue, need quick answer please.

[Bludger]

If anyone got a very good condition dc2 vtir overflow setup that is unloved, please post here so i can love it.

maybe minute crack in the plastic.

the hose size itself doesnt matter. as long as its clean and not bent.

now by saying its missing coolant. can you see coolant in your radiator when you open it ?

go to one of your mates garage and pressure test your system, if that comes back alright , then it would be your lid.

a cpc lid does the job, its costs 8 bucks.

now you say its letting the coolant out but not back , are you filling right to the neck then running the car then running it.

but my main question is when you say its not coming back, your looking inside the radiator and what do you see exactly, any coolant.


edit, worse case would be a crack somewere in the head. btw does your car always smell like coolant ?

lol i hate cooling problems, my s13 had plenty of them. used to chew more coolant then fuel~

I hate them too. drive me up the wall.

they are never as simple as diagnosing other problems. any other thing and i will have an answer, but coolant just shits me.

[Bludger]

bought another cap, see how we go tonite.

how easy to pressure test?

never had 1 done.

dont you need that special tool?
saw it in service manual.

Did you re-use the old head bolts?

[Bludger]

Friends car, not sure if reused.

Pretty sure everything was new.

You tuned this car Adrian. First had OBX cams but bad build, then purchased toda cams off you and then you tuned it, remember?

LOL...Vague memories... Sorry, I tune a lot of cars (It's easier to remember with faces & names rather than internet nic names - I never remember who is who through that)
If they're new, I'm barking up the wrong tree...
If they're re-used, there is a chance there is seepage past the head gasket.
The magic blue liquid will tell the story.
& the fix could be a simple as swapping out 1 head bolt at a time & replacing it with a new one & a magic tablet for insurance

If I'm wrong on that,
Pressure test the cooling system & confirm there are no leaks.
If no leaks, you may have an air bubble in the head/engine & you need to burp it.
You can do the with a cut down 1.25L Coke bottle, a roll of electrical tape & a bottle of water.
A slight slope helps too.
Park the car nose up, cut the bottom out of the coke bottle, tap up the cap end with elsectrcal tap to increase the diameter to fit in the radiator neck.
Fit & fill with water well above radiator height, (approx 5cm from full)
Hold in place & start car(run)
Be sure to have the heater on too so the water flows through the heater core too.

if you can still see coolant in the radiator then its okay , just keep driving it, and checking the top up tank and the radiator when its not hot.

you only have a problem when the level of the coolant drops below the fins.~

and by experience even then you can drive around.

infact i drove my s13 for about 15 minutes drifting with no coolant... worked good forever, pretty bullet proof.

just keep checking it, and use ure new lid aswell

[Bludger]

went melb and back.

went fine.

I think its head gasket, will check back soon.

^ any white smoke from exhaust? iirc it'd be blowing some white smoke if the waters burning in the cylinder
also oil or coolant milky at all? that'd happen if water/oil is mixing from the bhg

just another theory
are you using premix or concentrate?
perhaps theres not enough coolant and the water's boiling off forcing it into the overflow and out
when it cools down the pressure drops and so does the water level in the cooling system itself(and obviously sitting inside the overflow bottle and on the road)

[Bludger]

oil is fine, coolant is fine.

using Honda coolant.

will check back.

I'll check the smoke.
