help... steam coming out, can iput it back?

[jonboy]

hi all
i done a radiator flush in the weekend changed hoses /thermostate and coolant. now i have steam cooming out of the dash?? would i have a leaking heater core?
there is no wet carpet or anything just steam and my window is fogging up.
thanx

Sound like the heater core mine did the same, no water in the passenger foot well but steam coming out of the air vents.
Does your car have a burnt coolant smell?

[wrx884]

it might b comming out of the A/C pipe rather than on the floor like mine did. windows fogging up is a sure sign tho.

[jonboy]

yea it does have that coolant smell, my aircon needs regassing so it doesnt work, were is the aircon pipe? can i put one of those stop leek products n to stop it?

[wrx884]

aircon drain pipe i mean, mine only leaked out wen i used the aircon tho, which was strange but under the car its infront of the trans pan or there abouts.

since u got no aircon ud needa get that degassed 2 fix it neways so ur better off just replacing it while u got no gas, saves u the $$ and if u do it urself, theres a couple threads in here u can find 2 help u.

[jonboy]

ok kool
as my aircon isnt working it must be the heater core correct? would you try one of those stop leak products that you por in the radiator or are they a wast of time?
thanx

dont recon the core get a brand new 1 thats brass, they can actually b repaired if needed and they last longer 2. They r quite cheap mine was only $110.

Do use guys have laws about my by passing the heating?

[jonboy]

hi
thanx for the info about not recoring, i dont now about any laws for bypassing but my car has a farly new warrent of witness so it dosent have to get checked for a wile.
i will be bypassing tomorrow because now i have wet carpet on drivers side and its driving me nuts!
i dont no were to find a heater core but hopefully it wont be to hard to find 1

[wrx884]

ebay is the easiest 2 find but any radiator shop can get u 1.

If you changed the heater hoses under the bonnet when you did the hose change, you probably accidently wrenched the pipes coming through the fire wall, damaging the flimsy seal where they bolt onto the heater core tank. If you get a new heater core, make sure the pipes are welded onto the tank, not bolted like the earlier ones were......friggin' stupid idea if there was ever one!

this happenened to me when i did a coolant flush a few weeks back too. i did the coolant change at night in the garage. finished up thinking all was good after driving around for 5 minutes with the heater on, went to sleep. topped up the coolant before i left, then on the way to work, i noticed steam (though it was smoke for a few minutes in my half asleep state) coming out of the dash. i quickly pulled over getting ready to do a dash for the fire extinguisher, and realised it didnt smell like something burning, but more like coolant. i cautiosly drove on anyway, and it went away after 20 minutes. when i got home i topped up again (hours later obviously, so i could remove the radiator cap). i noticed a grommet on the flywall was not on properly, so i pushed that in correctly.and the steam never happened again.
but.. i KNOW i have a slight intake manifold leak (leaking coolant) so was left thinking that steam came out the manifold leak, because of less coolant than meant to be had been bleed through the motor yet. with the grommet on the flywall dislodged, the steam came from the engine bay, through the grommet into my dash.

it spun me out a lot when it happened.

check your flywall grommets first probably jonboy

[slowandlow]

oops. i just read further that your carpets got wet.
disregard my advice sorry mate
did u put the tablets in when you replaced the coolant. i find they are good for stopping older rubber pipes from popping off. a bit like a sealant. i didnt use them one time and my whole top hose popped off. luckily not too far from work

[slowandlow]

plus, no, u cant put the steam back in. haha.
well, u could, but i would like to see you try.
actually, no, i have better things to do.

[jonboy]

hi
yea im waiting to hear back from various radiater shps regarding a new heater core, thanx ill make sure its a welded one and not bolted. ill definatly check that the gromets are fitted correctly tho, and no i didnt use any tablets from holden, its a 304 v8 do i need them??
no i didnt replace the heater core hoses (yet).
i think that maybe it has leaked under the carpet for some time i just hadnt noticed but when i did a flush it amplified the problem.
anyway i have bypassed and no more smoke and smell so thats good and i have the carpet lifted and seat out to try dry it some what.
after i have fixed the heater i will remove all seats and carpets and get them properly cleaned.
thanx
