			There is foam insulation next to the tank.  My insulation was soaked from the coolant leak.  I pulled it away and let it dry before I put the floor and carpet back in.  You can see the foam in the left side of the picture after I pulled it away from the tank.
 There was a slight smell after the tank replacement, but it went away.  No clue about your smell.  Maybe you should just give it some time.
