Where there's smoke...

[jhstatts]

Hey... I have some "steam" coming from my vents when I turn the heat on. It does this regardless of settings. Smells sweet, so I assume it is coolant getting somewhere it shouldn't. I don't think it is just condensation. I just installed a new radiator, but it did this before the new rad. I don't like hearing bad news, but think I am prepared.

Runs pretty great aside from this, but is not as smooth at idle as it used to be.

Thanks all.

What proximity should I be checking? New to the heating system.

Thanks.

...and if the heater valve and lines are fine I'd guess a bad heater core. From the pictures in the service manual it likes like a PITA to replace too...

Hmm. I don't really see any cracks or leaks... it does this more in the morning hours than afternoon. I really couldn't replicate the steam when I checked.

I was thinking heater core too, but hoped it might be something a bit easier (and cheaper) to deal with.

Thanks for the help so far, guys.

you might just go through the whole system and replace hoses. that way you'll get a good look at what's going on, might just be a loose fitting.

by the way, what are you using the heater for. it's hot outside

HAHA. Yeah, it is hot. This can wait until closer to winter, I guess. I just noticed it when I replaced my rad. Had to ask.
