Coolant Smell in A/C

Guys,

Title says it all. I've got a coolant smell in my A/C when I run the A/C. Ideas? Where would I start?

Heater Core most defiantly. Easy to replace in the Super Dutys just have to remove the glove box. I bought my truck in the summer months and when it started getting cold I tried the heat, and there was none. The previous owner bypassed the heater core, and I had to replace mine. I have done many cores in cavilers and grand ams so I was very reluctant to do it. But after searching the web I found that it was a two hour job tops.

Thanks, guys. I appreciate it. I'll give it a look. How can I test to tell if the heater core is any good? We had some cold nights that I had to run my defroster and I'm pretty sure the heater core had no idea how to handle that.

Coolant Smell in A/C

If you smell coolant, its bad. That's how you test it.

Coolant Smell in A/C

If it leaks bad enough, you'll get tons of condensation on the windows and the floor on the passenger side will be wet. Could even get steam from the vents.

Will it smell whether it on cold or hot?

Mine went out 2 months ago, I could smell a little coolant coming from the vents and then it got worse and the windows fogged up. Your windows get a film on them as well. I opened up the area it is located at and I could see a little antifreeze running down the fins on the heater core. It took a few hours to change simply because I broke one of the plastic locks on the hoses going to the heater core and I had a hard time locating new ones at the local parts stores.

My last heater core was on my 05 Taurus. Thefunny part is, it was t the core that went bad. The inlet tube broke off at the firewall. Had to partially pull the whole dash to do that one. After that escapade, I got no problem diggin into a truck heater core. Lol
