Hey I was wondering if I could get a few tips on this.... My heater smells real bad, but only when it's taking in FRESH AIR and is IDLING. So, my question is if anyone has had this problem and how did they fix it. It kinda smells like burning fluids, but that was because my radiator was leaking and I had that fixed. Right now I'm thinking that it could be that I need to flush out my radiator, but I haven't yet cause it's too cold right now in MN. Any thoughts on this would be helpful.

 

You probably have radiator juice on some hot parts under your hood. It burns and will stink for a while.

I had coolant all over my H22 after I put it in. I had a leak in a hose, got all over the back of the block, my car smelled like a chemical fire for a while but it went away.

 

HAHA ...LOL
