heater core leak ? Need info ASAP

[jfbourgault]

I've notice a coolant smell in the ventilation of my car and i've also noticed that the coolant level is dropping( since 2 weeks, since the odors have appeared). I also have some sort of "foggy haze" in the winshield that takes forever to clear off when I restart the car after it's been sitting for an hour or so. <P>Now i'm almost 99% sure it's the heater core that's leaking some coolant in the system ( no wet carpet under the unit or anything). <P>My question are: <BR>1)As anyone ever had to replace that on their car? (it's 570$CDN for a new one and about 70$CDN for a used)<BR>2) Do I really need to remove the dash to do it? <BR>3) If not, does anoyone have a better way to do it???<BR>4) How long does it take<BR>5) Am I completely wrong about the heater core???<P>Thanx in advance folks!

Your symptoms are perfect for a bad heater core. I've never had to replace one in a MX-3 but they're a guaranteed PITA.
