Rubber smell...

just curious...when i shut the car off (after it has been running) for a brief moment it smells like i rubbery smell. i've read that it could be fan belt or something, but then it also said if it was that that it would make a noticable unusual noise. it sounds fine as it idles and accelerates, but then again there is a brief smell of rubber after i shut the car off. anyone know why?

when was the last time you changed your fan belts you may have two or one whichever check and see if they are loose if they give more than an inch tighten them and look at the belts carefully especially the edges
