After repeated unsuccessful postings here, I decided to post on another Volvo forum. I thank you all for the wealth of information I've found here. Hopefully all of the issues with the site can be worked out.
Thank you very much for the detailed pictures. I have a similar thing happening to mine and I am going to pull these panels off and see if this is leaking.
I'm hoping I won't have to do this, but it's nice to see HOW to.
I'm about to wade into an ABS replacement myself.
Now here's my question, hopefully someone can help.
I currently occasionally get a waft of the sweet smell, but it's not anything like you've shown in your pics. It's one of those things that's been on my mind for a while, but it's not a big enough issue to really worry about.
However, while I'm in DIY mode with my ABS unit I got to thinking about this.
What was the progression like to get to the point where you needed to fix it? Did it slowly build over time? How long did it take to get to the point where you needed to fix it right away?
I'm only planning on holding onto the car for the next two years or so, do you think I'd have to deal with it in then? It's a 99, so I know she's getting a little long in the tooth, but I'm trying to get a better top down view on what I should be expecting over the next few years to decide if I should bite the bullet and replace it with something now, or hold on.
I just started this project this evening.
Initially I believed it was the O ring connection, but after getting the pcs. all apart, alas the leak is from higher up beyond the O ring connection
HELP!
I followed the tips suggested in the accompanying article to the point where I am ready to remove the heater core.
I undid all the screws as was suggested, disconnected the 2 tubes that come down from the firewall.
I managed to dislodge it, but it is tight and I am afraid of breaking something inside.
Is there a proper or trick way to get it out and the new one in??
Thanks, I need to get this done, my wife is getting cranky about using my work truck.
is that it? that's easy as cracking open a fresh beer! I'm on it as soon I order the heater core, which will be next week!...thanks for saving me a headache and loss of cash to the dealer in labor.
Has anyone else had coolant pour into their cabin while disconnecting the tubes? And yes, I did drain the coolant before starting this, but its like the core stayed full of coolant and dumped onto the floor as soon as I started to pull the core away from the tubes.
Also, did everyone else follow the instructions from FCP groton and use 4 o-rings, 2 on each tube? I only found 1 on each tube when I pulled it apart, and it still had the original volvo core inside. I am assuming volvo only used 1 on each tube when it was originally installed. There was also some thin rubbery gunk around the tubes that looks like a sealant. Should I be using something to seal it up that is not mentioned here?
Just a note to other potential backyard Volvo mechanics looking to do this job... I encountered some additional steps to the writeup listed with pics. I had to take out my glove compartment to release the panel below it to get at some of the sarcophogus screws. The panel on the driver side only had a couple screws in it that were easy to find.
Thanks in advance for any insight on my findings above.
Use one o-ring per tube. No sealer. I use compressed air after disconnecting the lines to blow most of the coolant out of the heater core.
I pinch off the heater hoses and do not drain the entire system.

Tech, thanks for the input. When you say you blow compressed air through the core after disconnecting the lines, do you mean you disconnect the lines that run to the core from the other side of the firewall? Which ones? I have already completed the project, but this would be handy to know.
Also, should I not have drained the entire system? I drained from the bottom of the radiator, and then of course everything that came out of the core. Then when I filled the expansion tank, it took forever and a lot of gurgling to fill everything back up. When I started the car up afterwards, everything seemed fine. I used prestone green 50/50 with propylene glycol.
