Coolant Disappearing + Interior Coolant Smell

Coolant Disappearing + Interior Coolant Smell
I've recently discovered that my coolant slowly disappears. Each week to two weeks the coolant light comes on periodically, resulting in a coolant reservoir top off. The interior of the car also smells of coolant when the heat is on full blast. I'm unable to see if the smell still occurs on low heat due to a resistor problem (I think). I have a resistor ready to go, just waiting on some nice weather to install it. There are no visible leaks coming from the engine at all. I have done some research on possible causes and have come up on many ideas. Is it safe to say that I should start with replacing the heater core?

Most likely the heater core but don't assume that's what it is. You may have a small enough leak that the carpet isn't wet yet. Pull the access cover off and ck it out first. Easy to do...
If it is the heater core, this is fairly easy job to DIY; lot of good info out there. Recommend going with OEM core too.

If you haven't found it already here's a good heater core R+R thread:

Thanks to all of thise who have helped with this issue. I finallt got the core, coupling, and hoses in. I have yet to crank the heat, but hopefully the stench isn't there. The only problem I'm having is with the bottom heater hose; it's not clipping into the coupling. I have it in there as far as it goes in hope that it doesnt fall out or leak. I've tried "jellying" it up, but it still won't clip in. I'm going to keep checking it to see if it will budge.
This is definitely a job that I don't want to do again lol.

Your talking about where the hoses go into the coupler on the inside of the firewall?
If so.. try loosening the connection of those hoses on the bottom of the core.. this should give you enough play to clip them in. then tighten the core end up.
That part drove me crazy for 2 hours... I went to bed and the next morning "click", right in 30 seconds.. Sometimes you just need to walk away and take a break..

I'll also have to wait for a day I have off to get down there again. I only had time to loosen the hoses at the core and try, and get my new blower resistor in. I didn't want to have a mess of coolant an hour before work.
